Mechanical Gifs Catalog

Each of the models below is available as a high-quality, laser-cut acrylic model in either kit or fully assembled form. All models come attractively packaged with everything needed to finish the model (even a screwdriver). No special model-assembly skills are needed: the models just screw together in typically 15-20 minutes.

Electric Motor Add-on

Electric Motor Add-on


This add-on allows you to add an electric motor to the Differential, Two-Speed Transmission, Two-Speed Transaxle, or Radial Engine Car kits. It includes a pre-assembled battery holder and motor, mounting bracket, coupler, and all the necessary nuts and bolts to attach the motor and battery holder to one of the compatible kits. 

The motor is quiet and safe: if you jam your finger into the gears of one of the models while it is running, the model just stops, without hurting your finger or the model.

Batteries are included!
