Adaptor Ring for A1 Mini Spool

iAfter printing a number of other reusable spools I came accross the A1 Mini Spool (https://makerworld.com/models/787956) and was impressed that it not only prints well, but fits back into the original refill box for storage. We have limited storage space for a growing filament collection, so this was a huge bonus. It works fine on my AMS lite, but my partner found it didn't roll as smoothly as it could in his [other brand equivalent of] AMS due to the flat sides, so came up with this solution. An adaptor rings is required for each side of the spool. They snap on easily, holding firmly to allow smoother rolling in a multi material system without risk of falling off. Each adaptor ring requires less than 20grams of filament and prints in a little more than 30 minutes.ng a number of other reusable spools I came accross the A1 Mini Spool (<a target="_blank" rel="noopener noreferrer ugc" href
