Contest Ended, Winner(s) have been selected.
Description:
The device has to be no more than 2.5" in diameter - it needs to fit in a cup. It will be 3D printed, and then plastic mold manufactured.
The device needs to support 100g of weight, not tip over, and stay afloat.
Specifically, the 100g weight will be no larger with a 2" diameter, and can be as small as .25" in diameter. I envision 3 adjustable, horizontal poles that are attached in the inside walls of the device, that can move vertically up/down, depending on the weight of the seed, and in/out, depending on the size of the seed.
Lastly, there needs to be a hole that is no smaller than .5 inches, at the bottom of the device so water can get through.
Ideally, I would like to see buoyancy / fluid simulations of this in action, to ensure it meets the above criteria. Any other questions, please let me know.
Wants:
I would like the model in STL or OBJ format.
Software:
- Any program.
Additional Information
I did not make this clear, per my initial description. I would need a .5" diameter hole at the bottom to float device, not only for the water to get through, but also for the roots of the seed to get through, while it continues to sprout. Please see added attachments.Additionally, the way that I envisioned the seed would stay at the appropriate level, is by having 3 adjustable horizontal poles in the inside wall of the device. Please see image attached, and also see my other project here on cadcrowd: Simple extendable / telescoping mini pole, for a reference of these horizontal poles.
I have received many great designs. I am extending this project for one more week to reply to a few more designers before I make my decision. Thank you all very much for your talent and effort on this. It is very much appreciated.

#48 Float adjust with thread - by Adriano Ordoz Barissa
by Adriano Ordoz Barissa
In this model I designed two pieces of easy molding where a nozzle system is not necessary in the mold for extraction, acting by forced extraction.
The parts function as a drill chuck, where by tightening the green part on the yellow float it lowers in relation to the water level and decreases the diameter of the hole.
I think this could be a good solution for the project.

#36 Sprouter Final 7.0
by Chamal Jayasinghe
The rotatable middle part can be used to adjust the height and the sliding parts can be used to adjust based on the size of the seed. To keep the seed tighten to the device a small rubber band can be used.
The design is complete and if face any issues regarding STLs please contact , Sorry and quite tired.....

#8 Sprouter and Seed Assembly
by Devondesigner
Moulded plastic floating sprouter body with self skinning foam injected under rim to give buoyancy.
The seed is held in place to prevent tipping over, by three moulded arms on living hinges as part of the sprouter body. These features are in place of the adjustable telescopic posts you describe. This should be easier to produce, as well as being a lot cheaper.
If you have any questions please get in touch.

by Stella X
Have taken into consideration buoyancy so made it hollow and not easy to tip over. Depending on the weights of seeds the bottom of the hole can be adjusted so the right amount of buoyancy can be achieved. The clean hole for the seed makes it easier to untangle when ready to be planted. For multiple sized seeds a net could be added. Have added handles for options to use poles to adjust levels in water. Adjustable poles ready if needed.
This is 3D print ready. Though for use a waterproof materials needs to be applied.

#51 Adjustable Floating Sprouter
by Alfath L.I
This model have 2 adjustable height surface, so you can freely adjust the height like you wanted. Around the tube, i put a part which will be filled with air in order to maintain stability of the tube and also act as buoyant reserve for this object. I put 4 parts in STL format. It is a really simple assembly, so i hope that you can figure it out by yourself.
If you're interested in my idea model of adjustable sprouter, but wanted something to be changed you can contact me by email. I hope you check out my model and tell me if you're interested in printing it.
and also thank you for the fun contest.

#35 The Germinator V1
by Michael Jonquiere
Designed with FDA compliant materials and important CoM considerations for stable buoyancy. This single part is designed to self-align in the tank, and automatically adapt for different weights of substrate. Parts stack well for storage and importantly the are DFM - very economical piece part price and tooling costs make this design future proof and reliable.

#30 Adjustable Floating Seed Sprouter
by sldraftingdesign
Here is my take on the design that you requested. Some of the design specs:
1) Ø2.5" Overall with Ø0.50" hole in the middle
2) 0.3000" tall with .050" wall thickness.
3) Uses a stackable Peg system that includes a retainer peg, adder peg, and topper peg with extensions to hold the seed at the desired height.
4) Pegs have (4) notches slots to go in the adjust in and out to meed the size of the seed.
5) Holes in bottom to allow water though.
6) Proper Draft angles and wall thickness for injection molding. Also 3D printable. I can provide all STL files if chosen.
Out of all the visible designs, this is the only one that is adjustable per your requirements.

#43 Floating Seed Sprouter Flower
by Decker
Here is a leaf or floating flower design to support the growth of a seed. I have placed a fixture that has fingers on it . This fixture will probably have to either come in various sizes to support smaller seeds or be manufactured like a comb with small bristles to hold the seed in place. Anyway, its a concept good luck in your product development. Feel free to give me a ring and ask for any product manufacturing advice. I have a very good background in product development and am always open to offering up free advice.

Discussion
Looking forward to seeing the winning design!
Hello there Stavro,
You mentioned in your description that the seed size could vary from ~2" to ~0.25", and that you would like the height of the seed support adjustable. I would assume that this is because there is some ideal water level for a seed to sprout (i.e. 1/4 submerged or 1/2 submerged?). Could you provide some info on where you would like the water line to sit? I would like to see if I can make a passive design (i.e. one piece with no moving parts) to accommodate the range of seed sizes and weights.
Also I would suggest that asking for fluid simulations is probably unnecessary. Some static calculations should certainly suffice to show that the design will be stable and support the required weight.
Cheers
Aaron

Buyer, can we get some "star" feedback or anything from you regarding our designs?
Submitted! Thanks for the fun contest!
People that don't show their design typically are copying someone elses.
Can you please kindly further describe below
" I envision 3 adjustable, horizontal poles that are attached in the inside walls of the device, that can move vertically up/down, depending on the weight of the seed, and in/out, depending on the size of the seed. "

flower pot
A plywood flowerpot using the capabilities of CNC. Many people enjoy container gardening, but the price and wintertime storage concerns mean they use a pot that is too small. I want a plywood pot that snaps together. 4 sides, a bottom, and a lip around the top. Design should be scaleable from 1 o 15 gallon. I am thinking interlocking edges and wedges to hold on a double thickness lip and bottom. Alternatively, whole thing could be held together with wedges. Open to all ideas. Bottom should be recessed from actual bottom so it can sit on a stand. stand included in design. Construction would be of 1/4 inch luann (doorskin) plywood. Comes in a 4 by 8 foot sheet. Pot would be cut out on a shopbot type machine.
wallet clip for keys/key fob/cash&CC/ headphones
As seen in the sketchup images, this rectangular clip functions as a wallet and clips onto the opening of a front pants pocket (an example is shown in photo's). I need YOUR help in finding an ergonomic & functional solution to securing a car key FOB to the clip as well as sourcing pro CAD files that can be sent to a CNC machining facility.
Hearing Aid Sport Accessory
Hi
I have a small product that I need designed and built in Solidworks (2014). The product is a sports accessory for a hearing aid that is roughly around 35mm x 45 mm in size. The product will be a silicone mould that slips onto the hearing aid and hooks around the ear, similar to how sports headphones have hooks around the ear to stop them falling it out when running. I have a 3D model of the hearing aid that I can provide you with (available in the following formats: .3DS, .OBJ, .WRL) that can be used as a reference. I haven’t worked out precise measurements, which is what I will need the designer to work out. I have a budget of around 160 USD for this particular project and the deadline would be 10th March 17. If it goes well I will also seek additional work, as I need more models creating. I have attached some rough sketches of the concept.
Please let me know if you have any questions,
Many thanks,
Jay
Knee-based Travel Mug Holder - New Product Design / Prototype
Commuters on buses and trains don't have cup holders, and so they are left with the balancing act of holding their travel mug in one hand, while trying read the paper or work on their laptops with their other hand. This sucks, causes spills, and is super uncomfortable. Commuters need something that's compact and foldable that can then open and attach comfortably to their knee (or another body part?) that will securely hold travel mugs of different sizes.
Replicate Macbook Pro Cover
We are looking for someone to help us replicate a shell case for a MacBook Pro in a CAD format drawing that will function and fit the desired measurements. Our goal is to be able to take this design to a manufacturer for building. This case will include two parts: a top and a bottom. These parts need to be able to be built separately.
Please see attached PDF for measurements
This design should also be flexible enough to be adjustable so we can fit both the 15” and the 13” models. These models will be first produced in a CNC environment so the file must work within those constraints.
The design should not include the bottom leg pads.
The case we are looking to replicate is http://www.amazon.com/Speck-Products-SeeThru-Raspberry-SPK-A1498/dp/B00937DOEK
We have most of the measurements but a second look would help.
Wants: someone who either has a mac or can get their hands on one to see the coverture on the top and bottom case. Something that will actually can be produced.
Main focus is on the 15" model case.
Extra: additional Money can be earned if also completing the older version of the macbook pro case. also included in the PDF. 2012 version. $50.
