Description
A tool for pulling bearings from various housings, such as motorbike bearings.
Instructions
1. Break off support structure at entrance to nut trap hole
2. Slip nut into nut trap.
3. Insert 8mm threaded rod (about 600mm should do) into the bottom
4. Twist threaded rod through the nut and into the teeth at the end until tight
5. Insert the teeth into the inside of your bearing
6. Tighten the threaded rod till its very tight (But dont break the teeth!)
7. Pull upwards like crazy (Or better yet, put a nut on your threaded rod and a block of wood with an 10mm hole in it and then use it as a hammer to bang upwards onto the nut.
Its parametric, but currently configured to do the bearings on my dirt bike.

Did this end up being strong enough for the job? Did it break? What did you print it with ABS?
I printed it with PLA - it didnt break with my bearings, but i guess some bearings are probably quite wedged in there... as always let common sense be your guide
