Hey! This thing is still a Work in Progress. Files, instructions, and other stuff might change!

hello, looking at your robotic arm, I thought you might like this project, "magic lamp completely made of pla from 3D printers capable of making objects by hanging them with white light who wants can make it by downloading the plastic from

and asking for instructions to info@q3d.it or wait for it to come out in the tiger shops in this case you can book on the site at the price of $ 99 "


Hello! I'm not really sure about printed teeth, but I've got nice experience milling it. Works perfect in my plywood sentry gun project. Can you share drawing files for arms and base teeth? I'll make milled inserts for them. Seems that this will do it quite well)

Done. Took some time, as I had to find the source data first :D. I's uploaded in thing files. Good luck.

Sure it will work much better. It will take few days, but I will upload them among thing files.

Great project! Do you plan to upload a video of the arm in action?

Thank you for suggestion. Next time we will make some ;)

Edit: After we will print the arm again as it melted in car when was hot outside ...

Do you have a plan to make an automatic tool changer?

Yes, and the original plan was even more bold :D, but I am not sure how much we will be able to manage in the end and how much we would like to release under GPL. So sorry, no promises. Right now we are focused on get it moving, printing and manipulating stuff using common parts in reprap community so everyone can enjoy and develop their own applications.

Nice project! For the micro-controller and motor shield maybe could try 'Geeetech Rumba ATmega2560 Controller board' :-)

Thank You for the suggestion. Just recently got my hands on Arduino Mega with RAMPS 1.4. It should be similar setup concerning the computing power. I hope it will suffice.

Neat setup. Most arms on here are crude servo driven ones.

Looks very printable too. I'll have to give it a shot sometime.

Thank You.
Well, everything have its advantages as servos are much cheaper and easier to drive. But I'm more concerned about precision.
The prototype is almost done. Later this week I'll check the mobility, revise the BoQ and if everything will be OK, I'll remove the the work in progress tag for printed parts. You'll be welcome to print it. Although the development will not end up. Next plan is to make the same arm of laser cuted aluminium.

It took one month instead of a week, but it is assembled. It is far from ideal as it was made on two printers and each have a deviation of 2mm of 200mm. Unfortunately one is printing smaller and one bigger :D. As a result the teeth are not matching the belt, so after recalibration I will have to print some parts again to check if the models are prepared correctly. Now is time to set it in motion. BoQ will be revised with the next revision of printed parts.

WoW. Very nice idea. Did you have any printed prototype of this?

Thank you. I have only few parts from version 1.0, mostly with some mistakes that were corrected in 1.1. New version is printed now but it will take some time.
