Use up all your empty Sunlu reusable filament spools and organize your 3D printing area by printing this easy rotating hardware rack. Can easily be expanded to accept more spools. 
 

-Spring needs to be split to objects if using STL.

-Assembly of the base only requires 1 M4 heat set insert (6mm height should work, just make sure insert doesn't protrude into hole), a M4 bolt (10mm length should work), a piece of ¾" (ID) PVC (length is up to user). 

SOME RUBBER PADS ON THE BOTTOM OF THE BASE MAY BE NEEDED TO STOP BASE FROM ROTATING.

            -Heat set insert should be installed into base (just make sure insert doesn't protrude into hole)

-Super glue for the rest

            -Glue bottom to bin once spring clip is inserted (DO NOT GLUE SPRING CLIP AND ARMS TO EACH OTHER OR TO THE BIN)

            -Glue can be used on bushing when inserting into spool

            -Glue rail into spool to ensure alignment.

 
-Washers should be used in between each tier to stop other tiers from spinning.

-Offsets will depend on your printer, tight fit needed for Bushing/Bearing.

3MF comes with an Angled Bin, will upload at a later time.

PRINT QUANTITIES FOR FULL ASSEMBLY OF 1 TIER
1 - Base

1 - Rail

2 - Bearings

1 - Washer
8 - Bins

8 - Bin Bottoms

8 - Springs (split into objects to print arms apart)

The amount of dividers is up to you.
