A printable connector to turn basic wood/metal/plastic dowels into filament spool racks. I intended them to hold spools in place on an existing shelf or inside cube storage (like the kind at Ikea).
PLEASE NOTE:
- The middle rods are not included; these are meant to be used with existing dowels.
- These aren't very sturdy on their own - they work best when “converting” an existing shelf to a filament storage shelf.
The goal was low filament usage in a fairly specific use case.
These can potentially work freestanding, but for that, I'll honestly recommend other more sturdy models that are available on MakerWorld and other 3D model sites.
In my example (see photos), I used ½" (~12.7mm) wooden dowels from a hardware store. They were cut just a few mm shorter than the inside width of an Ikea Kallax cube shelf, then these prints turned each cube into 2 rows of filament storage. Combined with wooden dowels and wedged into an existing enclosed space, they work well and use very little filament.
For a longer distance, a ½" dowel would bend in the middle so the raw files also contain numerous variations to support larger dowels.
Pieces
The included print profile is a “complete set" of 4 bases and 2 legs. The profile only includes the 13mm bases, which can accommodate ½" dowels (or anything less than 13mm).
How To
Two bases can be paired with two dowels to make a rack. The dowels simply drop into place, then the weight of any filament spools will push the dowels down and apart, “locking” them in.
Legs can be added to make a rack taller.
Legs can only be installed one way, and there are arrows on the back to help line things up:
Stability
These aren't meant to be the strongest racks available, but there are a couple options for adding stability.
Print Settings
These can use the built-in 0.20mm Standard profile in Bambu Studio, but increase to 3 walls.
I'm open to feedback, but may not be able to make significant changes to this one.
Feel free to remix.
