If you have to remove any 608 bearing from a tight spot, and you cannot simply push it through from the other side, this tool will help. It generates an even all round pull, and as long as its not too tight, the tool will do the job. (Remember its printed in PLA, so if your bearing is absolutely jammed in it may break the plastic)

There are 3 parts that can print on the same plate. I used the .2mm STRENGTH print profile, with auto tree supports (that only generate for one of the parts). If you use my profile, the tree supports are optimised for easier and cleaner removal.

The parts have some tight tolerances but print fine on my Bambu P1S. I have included the step and F360 files in case you want to adapt it. The F360 file is parameter driven for the main dimensions.

How to use it

1. Screw the pronged part into the hub so it looks like the pic below. Screw it gently all the way down.
2. Gently squeeze the tips of the prongs together and push into the hub of the bearing to be removed. See video below. The first time might be tough as the tolerances are tight, but it will go through - in subsequent uses it will get easier as the fine edges of the prongs wear off. Practice this on a bearing that is not the one you want to pull.
3. Carefully insert the pin through the hole in the pronged part (again it will be a tight fit as the edges smooth down, be careful as the pin is VERY DELICATE.
4. Once the pin is pushed home, the prongs are locked open and cannot close until the pin is removed. Gently unscrew the pronged mechanism from the hub. It will pull the bearing from its home.
5. Remove the pin.
6. Remove the bearing from the prongs and you are done!
