This is the rotated version of my secondary spool holder for the A1 Mini. I nedeed the space on the right for a filament dryer. To avoid collision with the cable chain and the printed model, i had to move it to the left, which required some kind of safe filament path. So I added a filament guide. It can rotate and moves with the z-axis. You should stick a piece of ptfe tube in it to reduce fricton. The spool is facing to the front, which should make it easier to change the filament.
There are 3 parts, put it together as seen in the pictures. You will need 2 original sized screws.
