eSun spool adapter for A1

I created this adapter for eSun spool reels to use with the original spool holder on the A1. I noticed that eSun spools, being made of cardboard, are heavier and create quite a bit of friction on the original holder, causing strain during printing. This adapter allows the spool to rotate more smoothly during printing. It is designed for the A1; I found many models for the A1 Mini, but none of this type for the A1. The A1 Mini versions are not suitable because they cause the spool to hit the filament guide tube. I hope you find it useful.
