Z stabilizer i3 plus

This is a remix of the design of Aldiprinter https://www.thingiverse.com/thing:2625032.
I added a 22 mm, 7 mm high bearing to it. This bearing has a tight fit!
You have to disassemble the top part of the printer!
You can use 12 mm or 16 mm bolts.

Update; The previous version won´t work.
So here the new version.
