12mm U Groove Bearing - mold ... mold

This ist a mold for a 12mm linear guide u-groove bearing.
Fill the printed mold with silicone and you get a silicone mold for the bearings.
You can use the printed thing to stabilize the silicone mold as shown on the pictures.

It is not really necessary to use a release agent, but it makes it easier to take things apart.

The inner bearing is a 10x26x8 mm

I use an adapter for 5mm screws
