The file 'Mini Breadboard Tank Robot 3D Printer Model' is (stl) file type, size is 191.9KB.
This is a small treaded robot which holds 2 miniature breadboards on top, is powered by standard N20 motors, and has ample room for a 3S battery inside. The tank tracks (#43903) and wheels (#13971) are standard LEGO, meaning the entire robot is very simple to make.
To see the assembly, I have a second one listed in the makes below.
Required materials:
(4) M2x20mm screw
(2) M2X12mm screw
(4) M2x8mm screw
(4) M2x6mm screw
(2) N20 motor (I recommend 600rpm 12v)
