Sunlu spool adapter for smart materials 3D refill

Based on the awesome model of @design element, but specified for my needs as I've been using quite a few rolls of refill from Smartmaterials3D and I had a bunch of Sunlu spools laying around. Mechanism just twists and locks with both parts of the spool. Works good with the AMS. Should be made out of PETG if you're thinking about drying the spools eventually. Fit to the smartmaterials refill roll should be tight enough to prevent them roll around inside the spool.
