Summary

Moved to South Korea, they don't like putting nails or screws into walls here and my daughter has a lot of canvases we need to hang. ;) We haven't unpacked the Ender 3 Pro yet, so I haven't had a chance to try this print out to see if it works. I'll update again once we do.

After the first printing I realized the little up arms weren't necessary. In fact it works better without them.
