Spindleholder for the MPCNC (mostly printed CNC)

I had a lot of problems with spindleholder downloadet from Thingiverse. I never found the right holder for me. The moste of them wasn't rigid enough for my MPCNC. So I deciedet to design and print my own spindleholder wich are specific for my needs.

Maybe some of you have the same problems and can use these files to solve them.
