Screwspacer 20mm

Used it for https://www.printables.com/de/model/355849-prusa-lack-enclosure-extended-bottom-corners

I had some screws, that were ab bit to long, so I designed this distancer, which simply can be inserted in the hole, before putting in the screw.

In the second picture you can see that my screw was to long.
