Eureka - 1 pound plastic ant combat robot

thingiverse

Summary This is my first CAD designed bot. It is designed for the 1 lb plastic ant division and still very much a work in progress. Update: It seems like the smaller wedge works better than the larger one.

I drilled a hole in the top of one of the lids to have easy access to the switch. The angled sides of the wedge will need some kind of solvent reinforcement (even though the bot it made of PLA+ I tend to use ABS Cement). I think that is everything. Enjoy. PS. When I get my Nylon Setup going, I may try this in Nylon as well. But for now, here ya go. :-) Print Settings Printer brand: Creality Printer: Ender 3 Pro Rafts: No Supports: Yes Resolution: .2 Infill: 25 Filament brand: Duramic Filament material: PLA +
