Modular Filament rack with low profile casters
Works really well for maximizing storage capacity in limited space.
This model is based on
Filament Spool Rack - Stackable - Gluelessby ihateu3
Glue-less dovetail joints on the original design is a great feature.
Added features:

Casters are secured by #8x¾"length Teks screws or equivalent #8 ¾" length self tapping screws.
Redesigned upper frame to add extra tier with less material.
End caps are optional for finished look.
As the original design suggests, use 1/2 " EMT electrical conduit for bars.
I cut them for 28.5" which make a rack hold 10 SUNLU filaments per tier.
The one described in above holds 30 spools.
You can add extra tier to go taller, cut EMT conduit longer to make them wider or both.
If the space is extremely limited, you can make them single tier and narrow also.
You can adjust size of filament rack to whatever suit your need.
