Shelf Spool Holder - Single or Dual with Screws

This part is modified from an existing file found online. I have converted it to be used with thicker shelves (up to 30mm) and added an option for screws for easy removal and installation. I can modify this file easily so please leave comments if this is desired.
I created this version for my MMU2 spools outside of my RepBox set. This makes it easier for small/quick one off prints.

Print instructions

PLEASE use ABS or PETG for more strength. ABS is recommended.
If you want to use PETG I recommend adding 3 or more perimeters.

Must use supports on the Shelf bridge
