YARAF (Yet Another Robot Action Figure)
thingiverse
A couple of years ago I discovered the source model for this creation: https://www.thingiverse.com/thing:1695590. The arm joints would not function properly at 1:1 scale on my kit printers, so I imported it into Meshmixer and TinkerCAD to create a YARAF that can be printed by ordinary people without needing an extremely expensive printer. I printed these robots (shown in the picture) using three different brands of PETG on three different machines. Two of them were sub-$300 delta kits (Folgertech Kossel 2020 and HE3D K200), and a large bed Cartesian that I custom built from a Step file created by a friend. They all printed successfully, but the joints snapped loose just fine. I declared it a success and am publishing it now. PETG is not easy to print tight-tolerance print-in-place articulated models, so if you use PLA with a .4mm nozzle and .2mm print settings, you should have no trouble at all.
