This is just a spring washer, but it solved a problem I had since installing the CORE One+ spool holder: I couldn't get a suitable O-Ring at my local hardware stores and a search on Printables came back with only TPU variants that required flexible filament of specific hardness to work properly. This model, however, works with materials you already have on hand if you have printed the upgrade itself.
Instructions
Print with 4 perimeters in PETG (PLA will quickly loose it's tension).
When your print is finished, free the ring from the build plate, but put it back on. Crank the heat up to roughly 100°C (212°F) and get the removable part of the Spool Holder ready.
When the target temperature is reached, carefully put the ring on the mandrel (Spool Holder), pinch it with your index finger and thumb approximately 2 mm above it's resting position. Push with index finger and thumb of the other hand—offset by half a turn—to form the spring.
If you are not happy with the result, simply put the spring washer back onto the heated bed to reset it's shape.
