Hello!
I created this top mounted Tool/Parts Tray for my MB Micro Filament Spool Shelf System
This tray is a direct add on. It fits right on top of the shelf and provides a large capacity to hold accessors such as dessicant containers, snips, deburring tool, silica beads and tons more!
The original Filament spool shelf system can be downloaded at https://makerworld.com/en/models/126061#profileId-136209
UPDATE: Several People have requested washers. I have included 8 files. Four sizes of round washers from 2-5mm and the same for polygon shaped washers
