Sermoon D1 z-axis sync without tape

I remixed the sermoon d1 z axis synchro files from svalen for better look and i want to use the mounting holes in the back. I also want to use a longer closed loop belt.

Needed Parts:
- 3x 20T-GT2 pulleys
- 1x GT2x6 810 mm - 852mm closed loop belt
- some screws and nuts

You have to loosen the screw in the GT2 Pulley that is hold by the pusher part so it can move on the screw with a bit of grease freely.
