Shelf Spool Holder V2 - Single or Dual with Screws

an Upgraded smoother version than my previous make.  This is designed to be used with shelves up to 30mm thick 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 MMU2/3 spools outside of my RepBox set. This makes it easier for small/quick one off prints.

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
