3D Model 02: 3D-Printable Bevel Worm Drive Model

Add this nice-looking, educational, and fun working model of the bevel gear drive to your 3D-printed collection of things with the .STL files freely available from the link below.

You will also need 8 metric Phillips flat head screws M3x12 and 2 metric nuts M3 to put the model together. Those can be bought cheaply on eBay.

• We recommend that the two halves of the pinion shaft be printed with a raft for better coupling. The raft and remaining residue should be removed with sand paper.
• If printed properly, the crankhandle's grip should rotate freely around the handle.
