What to sell?

by TheNR04

I know that this may sound like a stupid question. I have been doing research for products that consumers can buy most, but most of those are either apparel or electronics. Does anyone have any ideas for what to publish on my website to sell?

3d printing services

by krvelvet

Can anyone here recommend a 3d printing service? I would like to print thymark's Compost Shredder (https://www.thingiverse.com/thing:356580) but I don't currently have access to a printer. I've been looking into it a bit, but are there any online services that one of you have tried and recommend to me? My main wants are low cost, shipping, and PLA or ABS. No special materials (like metal etc.) needed. Also, this design has many separate parts in it. Would this be a problem? How should I file these so I get my order correct? Thank you to anyone who can recommend a good service!

Getting an object to lay flat on a selected surface

by RamKat

Any DesignSpark Mechanical guru's out there? How can I force DS Mechanical to export an stl file with a specific face of a complex object at the bottom? Rotating the object manually is not an option since it will not be accurate enough. Since I can select a surface and create a plane through it, how can I force DSM to use that as the plane that will end up on the build surface?

Help with math and designing...

by skitcher

I have 2 circles, one with a circumference of 325 and one with 160.2212. I need to figure out how to space an object evenly around both circles, while the spaces between the objects around the circumference of a circle are equal on both circles
if that makes any sense

OR

find s

s n = 160.2212
s
u = 325
n and u have to be whole numbers

OR

an object has to be space evenly around a circle with circumference of 325 and another circle with circumference of 160.2212. the distance between the objects when they are placed around both circles must be equal

Im 3d designing tank tracks and I need to figure out how to space the notches on the tread and the bumps on the wheel so they fit together.

For example:
One circle has a diameter of 15 and another 20. I can space it out every 5 because 5 multiplies into 15 and 20 evenly. but what about the other numbers??

pls help...

big update for Papa’s Best STL Viewer

by Krishty

Hi there!

Since last year, I have greatly improved my STL viewer. If you didn’t know: It’s a very fast viewer for Windows which opens any STL, no matter how large or how odd it may be. It allows you to browse folders full of STLs in no time with the left/right arrow keys:

https://www.thingiverse.com/thing:2787757

Did you miss Drag & Drop? Now it’s supported!
Prefer US/Imperial units over meters? Not a problem any more, just check the menu!
Have a very old or very weak computer? The viewer now runs even without a graphics card!
… plus many other improvements.

For all those who await OBJ support: Sorry that I didn’t finish it yet, but as you see, the project is anything but dead. Just be patient!

If you have questions or problems, don’t hesitate to ask me!

Looking for a new printer

by sen2two

I curently own 3 printers. Creality CR10. FlashForge Creator Pro and Dreamer.

I very much like all 3 printers. And they do the job intend them to do. Strictly PLA on the CR10 and mostly ABS on the FlashForge machines. Niether of these do well or are even capable of (without exstensive upgrades) to move into the more compliacted prints and material I would like to use.

The CR10 works very well with PLA. But noe much else
The FlashForge machines work well with ABS. They are dual extrusion, but that dosnt work well at all. It does OK, with PLA, but not as good as the CR10.

I need (not want) 1 major thing in my new printer. To be ale to print with Ultem. A secondary want (not need) would be quality dual extrusion for soluable filament.

Anyone know of a printer that will work well with Ultem out the box and may possibly have a dual extrusion?

Movement library - like Spotify for robots

by megamikey

I was a kid back in 80s when our RC trucks servo motor busted and I opened it to examine what was broken. Then I realized that this was an interesting piece that converts electricity to movement. And I thought back then that how would it fit in a robot arm and in what ways to move it. Then I learned to program with different programming languages, but using a 386 PC there was problems to program a serial port to send a steady PWM signal to the servo. I left the ideas to grow and learned to make electrical soldering boards in school.

As older I tried it again with a BeagleBoard, but the idea was not in it's prime back then and I left it. At the same time I thought about this new technology that Torsten Reil had developed, using AI network to control single joints of a biped movement. I wrote to Torsten and suggested to make an Open sourced platform from their technology back in 2006, but there was no answer then. Then I decided to start making my own testing platform, first the idea was to make a simple role playing game like older Elder Scrolls games and to create character movements with AI. That was a tougher job to create and the project got halted. And the character had some simple movements and weapons like spear. Here's an example https://code.google.com/archive/p/gaima/

From there I thought that what would it be like to combine the technology that's used in computer games to robotics. Not meaning that robotics would have same features as computer games but thinking the ways how animation moves characters in 3d space.

So the newest project came with these ideas and is resulted in a new movement library. It's a library where you can store movements and modify and share them. With different configurations you can play the same movement with servos or different kind of serial connected actuators. The movement data itself is licensed with LGPL and there's a premium controller in beta test that offers a movement storage and playback inside from the Raspberry Pi device.

You can attach movements to Thingiverse objects where you can show the models and the configuration of the servos. Here's an example thing to move.

Hope to hear feedback from you soon and what you think!
