Benchmark Bot

Move over boat, there is a new benchmark in town.

This robot is not only a fun print-in-place figure but it is also a very useful calibration tool.

The robot is designed with 17 functional joints with different orientations, couplings, and tolerances. The tolerances range from 0.2 - 0.5mm and allow you to test the minimum clearances your printer can produce and still achieve print-in-place movement.

Each limb is labeled with the tolerances of their joints and all other joints have a 0.3mm tolerance. It might take a little (just a little) bit of force to break them free any more and you risk breaking the robot.

It only uses 20g of filament and is small enough to fit on a Prusa mini or even a Voron V0.

Print Settings:

No support!
No brim!

The point of the Benchmark Bot is to find the best parameters to make it function, therefore it is difficult to recommend any settings.

That being said, I used the following parameters:
0.4mm nozzle, 0.2mm layer height, PLA, 3 walls, 4 top/bottom layers, 10% infill.
