Air exchange valve for face masks

in 3D Printing Design held by honeysucklemay
Contest Ended, The buyer is selecting the winner(s).
Description:
We are looking for someone who has the ingenuity and gumption to help us design the next best face mask. The challenge if you choose to accept it is to design a fully functioning air exchange valve that can be implemented and used to enhance our current triple-layered cloth masks.

The requirements are:
1. The valve should be to be securely attached to a cloth fabric mask in such a way that it can either be sewn or glued to the fabric.
2. The valve should be designed in such a way that the end-user can choose to easily add a fabric filter inside of it, thus allowing the mask to still function as a means of protection for others.
3. The valve should be able to be printed quickly for production and still maintain a cost-effective value of filament material.
4. Filament material used in the design should withstand regular washing either by a handwashing method or by use of a washing machine on a delicate cycle.
5. Filament material should be resistant to attracting or maintaining contaminants that the sole purpose of the mask is to provide a barrier to.
6. The design should be scalable so that the final print size can be easily changed with minimal knowledge or steps so valves can be printed for each mask type and size.
7. The design should be appealing to most consumers and not detract from the overall design or appeal of the facemask.

Extra points will be given to those that also incorporate these "wish list" requests -

1) Final print requires very minimal if any clean up once removed from printer bed.
2) The valve design is easily adaptable to more than one shape (i.e. valve can be a circle or a square, or maybe even heart-shaped)
3) The valve can be securely attached to the mask but also removable so that end consumers can swap out the valve between multiple masks.
4)Filament material comes in more than 10 colors.
5)Lowest cost for production

And finally, if it was a perfect world and we could ask you to design anything (and yes if you actually include these in your design you get extra extra bonus points and most likely we'd declare you the winner immediately) we'd love for you to flex your creative muscle and incorporate these crazy ideas/design elements into your valve design.

1. We think it would be so uber-cool if the valve also could change the sound of your voice - maybe it made you sound like Darth Vader or daffy duck. Okay, Darth Vader is cooler - so let's see who can make us say "Luke I'm your father" then!

2. As you and we can imagine sewing a plastic valve to cloth is going to be a challenge on its own. So we wonder is there some gadgets that could also be created that would make it easy for us to use a standard sewing machine to attached easily? maybe a new sewing foot that holds the valve in place and allows the sewing needle to sew?? We don't know for sure and would love to see what you might create to solve this issue.

Another idea for attachment is using fabric or a fabric-safe glue. We've been researching different ways that current valves are attached to the commercial disposable masks. Most we've found are either glued or overlap the mask material but we are not 100% confident that using a standard fabric glue will hold up to the regular washing that our cloth masks experience. So if your final design/print of the valve incorporated a new way to attach it to our cloth masks in a manner that would not require us to use glue or a sewing machine to attach it to the cloth mask in an easy and simple manner and also did not puncture the fabric or create a gap between the fabric area and the valve.

Finally, we know everyone that enters will have to spend hours racking their brain to create something wonderful and innovative for us. A $100 prize doesn't quite seem like enough. So in addition we want to offer the winner the opportunity to consider themselves as our partner in crime (well not crime but design) and continue to reap the rewards as their awesome work helps us create a better end product. Therefore, we will offer the winner a bit of the $$ pie for each mask we sell that has their valve in it. The final contract will be negotiated once new mask line is ready for launch.
Wants:
Submittals will be judged on the following:

1. The Final design/product print meets all 7 of the main requirements.
2. The time of a single print is less than 10 minutes for 1 valve or 1 hour for 10 valves.
3. The size of the valve is relative to the size of our masks. We currently offer masks in a Small, Medium, and Large size. To see what our masks look like go to www.etsy.com/shop/honeysucklemay. simply view a mask offered to see pictures and access further details about the mask design and dimensions.
You can request a single piece of fabric or a set of paper templates cut to the final mask sizes for your reference. All requests should be sent to info@honeysucklemay. One request per designer will be honored as feasible.
Don't Wants:
1. A valve that is more than 1/3 size of the size or front area of the mask.
2. Requests for free facemasks.
3. Tons of sales pitches
4. Submittals that don't meet requirements and just clog up the review process - this is not fair to anyone.
5. Demands and/or attempts to pressure us to make a quick decision
6. Flaky and unprofessional designers who drop the ball too much and aren't passionate about their work.
Ask for Sample:
We'd love to see and touch a sample! We are open to accepting a sample to be mailed to us. Unfortunately, we won't be able to pay for the shipping cost though. But if you believe in your design and think us touching and seeing it first hand will give you an edge (we can be swayed this way just a bit - you know if you are in the top 5 it could mean the difference between winning and that second place participation pat on the back). We would also consider any requests for you to do a live video presentation too :)
Software:
  1. Open Source

#1 Face Mask Valve with Threaded Connection by bintangf
The valve uses thread to connect the parts. One part placed on the inner side, the other part that has three threaded 1/6 circle will get through the fabric with three holes. The part on the inside will be turned and creates strong assembly, without any glue or sewing. Additional filter can also be attached without glue, before you assembly it, put the filter inside, the outside part will be connected with the middle part and push the filter, making it stays in place and avoiding leakage.
For the Darth Vader sound, for now I haven't found any ways to do that without making it larger (but you want it to be small, not exceeding 1/3 of the mask) because the electrical component for it is maybe about the same size as the valve itself, adding that and a power supply (battery), I estimate it will be two or three times the size, but I'm still searching for it.
The model also does not require any support or cleaning, but I have not checked the printing speed yet. I'll develop these two later.
The model is not final, especially the looks, I think I can add more looks to it. I'm submitting this early to show you the concept, and let me know if you like it or have any opinion. I will continue develop this for the next two weeks.
Thank you
Bintang

hey, you mentioned about open source software but everyone don't use those software. what if i upload solid work file with step file also stl file (thus you can print it immediately for checking it ).Also i will make changes as per your need 'if' you like my design and it gets selected.And please make this contest blind.
Fri, 08 May 2020 21:06:27 +0000
Hi. This is a great idea, but for me, this is bit on the edge of my expertise, so maybe you can help me with a bit more information. You refer to a valve, and in my engineering world, this controls the flow of fluid, but I am unsure if that is what you are trying achieve here.
For example, is the valve supposed to allow air to pass through when the person breathes in, but not, when the person breathes out?
Or, is it meant to allow a free flow in, and a restricted flow out?
Or maybe something else??
Many thanks

Rob

2 ring designs for 3D printing/lost wax casting
looking to get the first 2 rings of my design recreated in CAD so i can get them 3D printed to be used in lost wax casting, the final products will be made of brass. RING 1: rectangle face with approx 28mm X 24mm with bart simpson engraving, in 2 sizes US10 (dia 19.84mm) and US8 (dia 18.19mm) RING 2: square face approx 14mm X 14mm with spider web engraving, in US6 (dia 16.51mm) and US8 (dia 18.99mm) each ring will need to have a sprue for casting, please see pictures provided. please see design sketches for rough idea of how they should look. i have included photos of other rings with a similar finish/engraving looking for someone that has some experience with 3D printing for casting but not essential, i also have more designs really to go for use on the same rings so would like to do more after these. this is the first time i have posted on anything like this so any feedback would be greatly appreciated. any software that can generate STL/STEP/IGES files should be ok price not set in stone either

Trim Scissors Necklace Pendant - Tritium Vials - Shapeways 3D Print
Hey Cad Crowd! Got another project for the personal jewelry collection I'd like done. Trim Scissors as a necklace pendant. Trim Scissors? Yes, Trim Scissors. I work in the Colorado Cannabis industry and a sign of good times to come is trim scissors. Nothing more satisfying than sitting down at a table and manicuring your hard work after busting backside for several months. So I'd like to make a scale version that will work as a necklace pendant with some Tritium vials in the handle portion for additional cool factor.
CAD Design for Four Simple 3D Mathematical Functions
Hi there, I am planning to do some 3D project that needs to be printed by a 3D printer. In order to do so, I need to first have a CAD file of my 3D objects/figures, and I have no clue how to do the CAD design by myself. So, this is why I am reaching out to you. Speaking of the project that I have in mind and now actually ready on papers, I would say that I need someone who is able to design the CAD files of four 3-dimentional mathematical functions (very simple 3D planes/surfaces which are supposed to be placed in a cubic framework which is 10*10*10cm^3 in size) with some certain specifications (colors, thicknesses, etc.) that I have already decided about and everything in form of a 2D version is on papers right now. To be honest, although my project is pretty straightforward, I want it to be done very carefully and professionally. I just need someone who is expert enough and patient enough to make a nice professional CAD file for me. I have roughly one week to get this project done, and everything with that should be done by Friday 23rd. However, the sooner, the better! I will await your replies. Best, Ali
Coin Face
I need a cool looking "coin", 52mm diameter, 4-5mm high, but hollow (because it's half the coin really, I have the other half done), with a 1mm edge all around, hollow cavity 50mm inside the edge and 2 mm high, leaving 2mm for the face which can be embossed like a real coin. It needs to be printable on a hobby printer with .4mm nozzle
