- the shortest length when fully compacted, will be .4375 inches (or something close to that) (7/16inches)
- the apparatus will be 1/8” long (grey area in image)
- the diameter will be slightly wider than general pole diameter
- apparatus will have largest diameter
- then base pole will have smaller diameter
then extension pole will have smaller diameter
threaded area should have same diameter as extension pole
Wants:
Please refer to images, and refer to size from Description above
Ask for Sample:
Should I receive sample? I am not sure. This is my first request.
Software:
  1. I have to be able to 3D print it
Additional Information
I am adding a second prize, since there is not just one proposal that is more than adequate.

I am also extending the contest for another 10 days, mainly because I am free during the weekends to effectively be able to communicate wit the designers.

Thank you all for your great designs and input.

#26 Extension pole by Kenan Kalamujic
By turning the apparatus, preasure is applyed on the top of the jaws, which move down into the hole and the jaws move towards the extension pole and provide preasure that locks it in place. Its easy to assemble and to print.
The jaws should be printed out of strong flexible plastic as for other parts it can be PLA ABS or which ever one you want. I recommend that you also print the holder out Resin, becouse of the threads. this concept of holding work is also used in machining. Which was the Idea I based my design upon.

3D Printers use files called .stl files. The printer reads the .stl files which are like little triangles that make the shape of the object you will print. I've attached the .stl of the extendable mini pole so you can upload onto your 3D printer and print it out!
Hope you like it! If there are any changes you want me to make, I'll be happy to do so! Thanks :)

#6 Telescoping Pole by jabable
The two poles are the same length as per the design requirements. I would be willing to work with the designers to change dimensions and threads to whatever they want for more practical manufacturing. I am very familiar with additive and subtractive manufacturing. I have access to a wide variety of manufacturing equipment and could assist with prototyping and troubleshooting as well.

#10 Simple Extendable - Telescoping Mini Pole by MT Designs
As Per your comments, please find attached the Mini Pole Concept. The design contains a stopper such that when the pole reaches the 7/8" it stops at its maximum length. However, when retracted it needs to be a little longer than what you specified as you cannot double the length of the pole exactly without having a hole at the bottom of the larger diameter tube. If you have any questions let me know.
Thanks for the opportunity.
Best regards,
MT Designs

#12 Extendable/telescoping mini pole by Kenan Kalamujic
All parts have threads in them which allows you to accuratly extend the pole to the requiref hight. Also Apparatus perfomes like a second nut, so that when you extend the pole you just tighten the apparatus to keep it in place. Also you pole is a bit longer and it allows you to have more hight if needed. If you have any further questions please do message me. I will reply asap.
Best regards

#15 Extendable Mini Pole by Stella X
The current file is ready to print in plastic. For other materials file can be modified. There are tiny bumps on the domed pole which can be made bigger by inserting from the other end. Right now it can be inserted from the top. The apparatus is loosely attached, can be changed to screw on.
If .stp file is required I can upload. Thanks

#17 Extendable Mini Pole by Stella X
Ready for the printer. The domed pole has two bumpers and can be inserted into the slot in the middle pole. The threaded part and the middle pole is printed in one piece. The apparatus is movable and can be modified to add thread etc.
Step file or others are ready if needed for production. Thanks

#18 Simple extendable / telescoping mini pole by Kenan Kalamujic
This design uses three jaws that are tapered on one side and flat on the other, so that when tightened the taper jaws will contact with the taper in the holder providing friction on the extending pole. Meaning you can set it to any height and not worry about it slipping. I hope the explanation is simple for anyone to understand I provided stl file of all parts.

#21 Extendable Pole Model 1 by Vivek Revi
The design was made as per your idea. The dimensions are approximately correct as per your recommendation. Here the apparatus is the driving member with inner threads. But here, how the assembly of the apparatus to the base pole should be done after manufacturing needs to be thought. Considering this, I'll post a modified design soon.

#23 Extendable Pole Model 2 by Vivek Revi
Just thought of adding something, to prevent the pole from rotating inside while extending/retracting. So, Added a key and key-way inside the cylindrical part and at the end of pole respectively.

Regards. What is the purpose of the device? You need it to be graduable or two positions only.

What will be your 3D printing material? If the base pole diameter 1/8" (3.175mm) then it is too small to have inner pole.
Do you interested in some other manufacturing processes? Metal machining is definitely realistic.

Nevermind, ignore remark below except that statement regarding threads. You should be ok.

This won't work for 3d printing. You need a minimum of a.030" wall thickness to 3d print.
With the base pole being .125" in diameter, with a .030" wall thickness, the inner pole will only be .020" allowing for clearance.

The base pole need to be 3/16" minimum.

Threads can't be 3d printed, they need to be post process tapped.

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
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

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.
