I was frustrated with not being able to find the correct threaded insert parts for my beer tap handles. I know you can find brass ones, but why not print them?

I have included two models, the only difference is the exterior dimension, the internal threads are the same. The metric insert is 18mmx20mm and the imperial insert is 3/4"x3/4". Use Thingiview to flip the model and view the threads.

You can remix these inserts in your own tap handle designs for printing. They are designed with proper clearances for a filament printer for the 3/8"-16 thread commonly found on tap handles.

You can also drill a hole in the bottom of a non-printed handle you have made and use this as a thread insert.

I have even included a STEP file so you can import it and work within your CAD software to eliminate, add or modify anything you like.

Before you add this to your model, do a test print of just the insert to be sure it fits correctly. Then modify it if you need to and add it to your CAD model. This could prevent some wasted print time of a complete tap handle if your print settings differ too greatly from mine.

Enjoy!
