Z-Axis mod for bluer

After searching for Z-Mods, I didn't find a good one for my TwoTrees Bluer. I've designed this one with the dimensions of my printer and standard bearings (easy to find in France).

This design is using 2x M4x40 screws (either with T-nuts or standards nuts) and Skateboard or rollerskates bearings.

I've added a Ø3 hole in case you need to lock the bearing inside the part, but the adjustment should be enough.

Note that my print is not finished on the picture (my printer bugged in printing and the upper part of the print was 2mm aside...), but as the part was functional, I didn't print it again...

Hope you'll enjoy my first share (I've started 3D Printing 3 days ago...)
