    Looking good! Really nice parts, well done!

    Do you use PLA filament?

    Thank you Zenta.

    Everything except for two parts is printed in ABS. People kept telling me I was crazy and I definitely had some frustrating moments along the way. But it panned out. My recommendation would be to prototype with PLA first and then move on to ABS for a final part. I do have a printer (Spiderbot) with a PEI material bed, heated chamber (60 degrees) and a heated build plate (100+ degrees) so that really helps with printing in ABS.

    The other two parts are a material called NGEN from a company called Colorfab (link). It's pretty good material but much more shiny then ABS and they didn't have all the colors I wanted. Prints easy though. See the link for a comparison data sheet with PLA and ABS.

    Some better photo's attached. This is it for now, I have already started on a new project with a robotic arm and some vision to challenge myself more from a software angle.

    Definitely impressive design and dedication to get it all printed, but I can't help thinking "holy crap, that is a cool peg-board tool holder in the background" and now I want to make one for my desk.

    Hey Tician, thanks.

    To help you along with that peg-board. Here is some background information. I have several stainless steel desks which come from a kitchen manufacturer (cheapest I could find). The pegboard itself is from plexiglass and laser cut to my specifications.

    First I made a 3D Design. Actually this was just one small part of my whole study room design.

    Then I requested some quotes from manufacturers and made a set of drawings for both the glass and the stainless steel frame. I have them in .pdf if you'd like.

    I added two short blue LED strips on each side and used some simple 3D printed blocks to put the wiring under while the plate rests on top, they are powered by some 9V supplies and connectors from ebay. I checked the optimal blue light setting with my lab power supply. 9V was better then 12V.

    Then I made the 3D designs for the inserts and 3D printed them. The ideas/inspiration came from Thingiverse mostly: http://www.thingiverse.com/search/pa...=peg+board&sa=

    Some final results:

    It is not terrible sturdy if you push it hard from the side, but for basic tools it can hold everything just fine.

    Let me know if you'd like the 3D designs for the peg board items. I have everything in a Fusion360 project and I can invite you to it so you can check/edit/download the files.

    Was just going to use a big scrap of ~0.25" acrylic in the basement: mill a grid of round holes, maybe frost the surface to erase the existing scratches, bolt to some vertical tubing, and maybe add some neopixels. My desk is not too much younger than I am and is made from three round steel tubes bent into "C"-shapes then bolted together with a 24"x36" MDF main deck and a 10"x36" MDF upper deck. The upper deck is only 8" above the main deck which really limits usable space and has been visibly deformed for years, so just going to remove it and reuse its mounting holes for attaching long-term storage/display shelving with the acrylic pegboard as the front cover/door.

    I second that about the coolness of your tool holder, looks awesome!

    When it comes to your printed parts, do I understand it correctly that they are also the actual brackets, not only shell outside the bioloid brackets? ABS should be strong enough, but you don't have problem with flex of the material?

    That is correct, the designed and printed parts completely replace the original bioloid brackets. The have the same function (hole placement, bearings, nuts/bolts etc), they just look a lot better doing it.

    The really nice thing is that the total weight of the robot only increased 100 gram, going from ~2 Kg to ~2.1 Kg. This is mainly because the torso area on the original Bioloid contains a lot of extra unneeded material, which I do not have. The 3D printed parts can furthermore be printed hallow, saving weight. Some stress analysis was done on the more tricky parts like the knees, just to be sure it could hold it up and not break.
