About this 3D model
You will need : 16x 10mmx10mm magnets 6x arms 6x arm bases 2x heads (happy and angry) 2x middles 2x bottoms 9x pins Newer version of Hiro's bot , entirely redraw from scratch, here are the changes : Switch from 9x5 magnets to 10x10 magnets (parametric model, so I can easily rebuild stl files for different sizes of magnet) Improved connectors Added both happy and angry faces, you will need black, white, yellow and red filaments I printed and tested it with PETG, it works great I provide the 3mf file with all parts to print, variable layer height I added a drop of glue on every magnets to prevent them to make noise when shaking, and also on splitted parts to assemble it permanently Tips : Assembling the bodies parts can be tricky with the magnets, use masking tape to hold them during assembly, and remove it at the end before to close it.
