I love my filament storage rack from Brownbear. However, it looked unfinished to me since it is an extendable, stackable system. I designed a matching element to be used as the top layer. The top element is tested and in use with v2 of the rack system. According to the description of the original creation, it should be compatible with both v1 as well.

I wanted additional stability for my Filament Rack from Brownbear. I made these pole end caps to be able to use the full length of my 90cm poles.(Edited)

Filament Swatches are a must. I remixed the ones from RVA Labs for a cleaner design to my liking.
