I printed the robot at 150% scale to make it sized for my 2 year old son, but this was a lot of filament. However, all attached models are sized to match the the Modular Toy Robot Arm that I remixed this from.
Print and Assembly Recommendations:
- All parts with gears must be printed laying all the gears flat.
- Gears may fuse a little, but will break free with a bit of force. If need be, a razor blade can be used to break apart layer gaps for print in place pieces.
- I needed a razor for test prints at 100% scaling, I did not for any printed at 150%
- Robot Body gears had to be printed separately from the the robot body cube and glued. I glued 5 of them with superglue and 1 of them with hot glue. This is to ensure I can remove one of the gears to retrieve anything that falls inside if needed.
- Since supports are needed to print the robot cube body the best gear to hot glue is the one on the bottom, the supports will leave a rough surface that the glue will adhere to better.
- Joiners are not glued
- Print the joiners with ‘Fuzzy Skin’. It will give them better friction against the parts and hold them together better so they don't have to be glued.
- Any female joint that prints with the joint at 90° to the joint may need to have the layer lines sanded so there isn't too much friction and the joiners get stuck.
- Print the Hips upside down
- Swirls Plates have alternatives
- There is both a ‘single swirl plate’ and ‘swirl plates’ with the latter containing 3 plates so you can print them in one print.
- The following pieces need supports (all others do not, just rotate them).
- Body Cube - It was either supports or make it solid and use alot more plastic
- Hips - same as Body Cube
- Swirlbase - minimal supports if you print it face down
- foot_R and foot_L - a gap had to be added to ensure that a razor blade could fit and help free the gears after printing (if needed). Put supports on the gap, nowhere else.
If there is any confusion about assembly, just add a comment and I'll update the instructions to clarify.
If you like what I am doing, just send a friendly comment. Knowing people find my stuff useful and/or fun is enough, I do not require coffee or donations.
