Summary

Remix to split this in half so you can print on a CR6 (it wouldn't fit at 45 degrees or vertically).
Added two 'tabs' that could be glued to make it more sturdy.

If I was to do it again I'd rework the overall design: I used countersunk screws to attach to the rail, but the dryer doesn't actually sit on the bottom because the recess for the circular protrusions of the dryer aren't quite big enough.. Only the power cable keeps it stable
