FILAMENT BUNKER - SPOOLHOLDER - (Tested)

The main advantages of this spool holder:

• The base parts can be connected with screws, making it infinitely expandable. You only need to alternate connecting base A and B.
• A silica gel container is included to keep your filament bunker dry. 
• There are two types of rollers: one that supports bearings and one that doesn’t (personally, I use the model without bearings, but WD-40 is needed if you don’t use bearings). The bearing slot is designed for bearings with an inner diameter of 10mm, an outer diameter of 22mm, and a width of 6mm. 
• Additionally, this spool holder is designed to be very sturdy.
