This custom laser-cut chassis is designed to work with a pair of GM7 Gearmotors and our laser-cut wheels. The cutting work consists of two 3.0" x 2.4" acrylic plates that sandwich the two gearmotors. Cross-shaped cutouts on both plates accommodate plastic tabs on the gearmotors to lock them into place securely. The bottom plate has a large hole for press-fitting a plastic ball caster, and the top plate has a rectangular hole for holding a battery pack. Various small holes for holding the plates together and attaching a printed circuit board are included.
The drawings for the two plates are shown below, followed by a cost breakdown.
