u/Weary_ExtrudedPickle

This is my DIY sex machine. The main body is built from 2020 V-slot aluminum extrusions, V-slot wheels, and small L-brackets. The motor is an old Nissan wiper motor, while all the other parts were designed and 3D printed by me. The base plate is 3D printed and filled with resin to create a smooth surface for suction cup bases. It can also hold ties for larger toys. The base plate is secured with a drilled pin to prevent it from spinning. The motor runs on an old laptop 19V power supply paired with a generic Amazon motor controller.

It works extremely well — the motor never struggles, even under heavy pushing loads. The only thing left to figure out is how to keep the machine in one spot, as its strength causes it to push itself backwards.
