adjustable width and length/height spool holder

With this remix you can lower your spool as much as you want.

This is useful if you want it to fit into a box with a height that is slightly bigger than your spool height.

Requires at least two m3 screws with a length of about 5mm to prevent the holder being driven apart due to spool weight. You can use two additional screws for the width but i found it not necessary after trying out

You need 2x pt1 and 2x pt2 and also four bearings from the original design
