Anyone want models made?

Requests?

MaskedRetriever 20 Mar 2009 19:16

When I first saw Thingiverse, I wanted to contribute models but also didn't want to flood the site with stuff nobody was going to print, especially if I wasn't going to print them myself because a lot of the time there'd be no guarantee I was even giving the community something that *could* be printed. So I sat on my hands.

But then, while browsing this quite young forum, I saw someone looking for an isocahedron model, and this was easy, likely to work, and had an existing user wanting to print it. So I did it, and thus the .stl dice pack was made.

Question: anyone else have a need for some modeling to print parts? I want to try to model a gear box at some point, but it'd be best if I had a known model motor as a target…

It's going to be a challenge designing anything until we have some numbers on print resolution and grid step-size precision (especially gears), but a useful starting point would be to have some of the larger Lego/MegaBloks (both small and 'Duplo' size) building blocks as to try.

How about for starters some duplo-scale square blocks with the alphabet and digits embossed in the sides - vertical and horizontal orientation, capital and miniscule case. Stack a word and use it as an ink/paint stamp. Messy but fun. :-)

Unless I've missed something, the print res is 0.5mm with a step-size precision "somewhere near" that. My test at the moment has been to run stuff through skeinforge.py from the RepRap guys to check for printability and scale.

Building toys. I'll look into that :3

…and of course the whole reason 'Lego-compatible' came to mind was as a 'known model motor' target, i.e. Techniks/Mindstorms.

Ah, I see. I'm hoping to make a gearbox that works with as dirt-cheap a motor as possible, say in the $2 range. That way, for maybe a dollar worth of plastic and two dollars worth of motors, users can have the equivalent of a maybe ten dollar gearbox. Little mechanical gizmos like this have great potential for amplifying the value of 3D printing and getting it closer to that "wealth without money" tagline.

Of course, interfaces to mindstorms components also fit in to that picture pretty nicely ^^

In its activities (educational, scientific, artistic, technological) people daily uses existing and creates a new model for the outside world. They can form an impression about the processes and objects that are inaccessible for direct perception (very small or very large, very slow or very fast, very far, and so on)

I request a vacuum tool head.

John Meacham made an experimental vacuum tool head in May of 2008, but was never heard from again. He talked about his work in founding post of the "very rough prototype pick place head type thingy" thread at:

Gene Hacker later designed a vacuum tool head, but it was never made:

It would be great if you designed a vacuum tool head which could be fitted on the extruder holder and had no overhangs. Don't worry about being able to rotate the head, for the first version just being able to pick a component up and deposit it somewhere else is good enough. Indeed, for the very first version you don't even have to worry about being able to turn the vacuum off, a pick up demonstration would be good enough.

That's a complex request which may involve some non-printable materials, but its value is obvious, so I'll give some thought to it…

I think a neat model would be a printable buckyball :) might be a little on the simple side but something to test out the makerbot with.

I think my first project when i get mine will be to make some sort of contraption to auto feed the ABS from the roll that you can print out and either attach to the makerbot or set beside it or something. Simple but will give me something to learn with.

Actually a hollow buckyball turned out to be harder to model than I was expecting! For one thing, a sixty-vertex semiregular polyhedron isn't in my list of "script spit-outable" objects (sadface!) and my strut-generating script doesn't like it when I give it non-triangular faces.

Soooo I compromised and did this:

Thingiverse, incidentally, is where you will find maaaaany nice things to try printing out early one ^^

that is sweet; definitely going to print one out next month :)

I would like 10 layers of flexible plastic the ends would extend a little further.
Any non conductive material that is flexible and can be printed to is fine maby some kind of silicon.
On the 8 inside layers each would have 8 traces of conductive material like those plastic like strips in calculators with hinges.
The ends would stick out so it makes a 64 conductive pad grid.
8x8 the other end would hook to a electrical connector of some sort.
Powdered silver & silver cloride would be ideal.
This is for a electrical measurement device like EMG or EEG.

http://www.thingiverse.com/thing:417 got me thinking of an idea

I dont know if you are up to it but how about a version suitable to be printed by the makerbot? maybe even make it cylinder.

I would guess you would need to make it in 2 parts that slip together.

I only have 2 rolls of solder myself. here are the dimensions:
54mm OD 19mm ID 56mm Length
55mm OD 25mm ID 19mm Length
