Bevel Gear Box

This is a simple bevel gear box. Because no one's application for these gears are exactly the same, I've included all of the design files for both Fusion 360, and STEP. Remix to your delight.

If you're looking to learn how to make your own bevel gears, I recommend this video:

The video is not for beginner 3D modelers, but it at least teaches the principles.

Print instructions

At the scale of the design, I printed with 0.3mm layers in PLA and it was just fine.

You're going to need to print the gears with supports. (Flat side down on the bed.) In the design of the gear assemblies, you'll find a body that is intended to be used with a slicer to block supports where they're not needed. If you're using Fusion 360, you'll find it to be the last body extruded in the design history and it is labeled "Support Blocker". To be clear, you're not intended to print this part. You're intended to use the part as a support modifier when you are slicing the part prior to printing. See the last photo of the set included here.

You'll need a couple roller bearings like these to complete the design:
