A motorized rotating toy that combines three types of cat toys

Assembled dimensions: approximately 192×192×290 mm

• The “butterfly” on top rotates
• The “fish” in the middle moves up and down
• The “bug” pops out from the bottom

Due to friction between plastic parts—especially around the “fish”—the noise level can be quite high. Please assess your cat’s reaction accordingly.

The following components are required for non-3D-printed assembly:

• N20 gear motor (recommended: 6 V, 100 RPM or lower; the example shown at 150 RPM is slightly too fast). Please note to test the motor’s rotation direction before assembly: when aligned with the shaft, it should rotate clockwise! If not, reverse the polarity.
• Type-C female connector test board (I’ve also uploaded the STEP file for the model base; if you use a different power connector, feel free to modify the file yourself)
• M2×6 screws: 4 pieces
• 608 bearings: 2 pieces
• 6806 bearing: 1 piece
• For the pop-out section at the bottom, you’ll need some small fabric strips (I used ear loops from disposable masks)

Assembly instructions are as follows:
