TOP COVER for Quick and Easy ER20 Collet Rack

I Printed the Quick and Easy ER20 Collet Rack by IcanCwhatUsay and decided to add a cover on top to prevent dust. It sits nicely on top of the original holder.

There are 2 versions of the cover:

+ A fully closed (ROOF.stl)
-or-
+ An open version for adding acrilic glass (NO_ROOF.stl). I also carved the ⌀ sizes into the glass ;)

I also included the unedited original file from IcanCwhatUsay.
