I wanted a quick change spool holder system that was not a roller so I designed this one. Each segment holds 2 spools which are simply lifted up and out and replaced with another. Place segments side by side to create 2, 4 6, or more spool racks. It also has a buit in filament guide for each spool.

The lift out axle is a 10mm x 90mm aluminum rod but you could use anything that will support the weight of a spool.

It can be used with or without a spool adapter.

Print time was 8 hours.

When you compare this to a multiple quick change roller system you'll find that this is easier to build, less costly (no bearings), is just as quick to change spools, and is smoother running and more dependable.
