Multiple Spool Holder, Quick Change

thingiverse

I designed a rapid-change spool holder system without rollers. This one holds 2 spools in each segment, which can be easily lifted up and swapped with new ones. To create multiple spool racks, simply place segments side by side to get 2, 4, 6, or more. Each spool has a built-in filament guide. The lift-out axle is a 10mm x 90mm aluminum rod, but you can use any material that supports the weight of a spool. This system works with or without a spool adapter. The print time was 8 hours. When comparing this to multiple quick-change roller systems, you'll find that it's easier to build, less expensive (no bearings required), just as fast for spool changes, and runs smoother and more dependably.
