Summary I had a few Hexbug Nano toys, but the feet wore out and fell off. The toy became useless, so I designed a replacement set of feet that attach to the bottom of the HexBug. My daughter is enjoy them all over again. Required: Remove all the nano bug feet Note: I recommend printing with a semiflex material. Print the model flat on the bed with feet in the air. Note: There is (2) different models, both are the same except of the the feet. Round vs Flat. Print Settings Printer Brand: Prusa Printer: i3 MK2S Rafts: Doesn't Matter Supports: No Resolution: 0.10 Infill: 100% Notes: Material: TPU/SemiFlex Filament How I Designed This Fusion 360
