Previously I made a stealth scraper holder mount for my A1 Mini and decided to utilize the screw holes on the A1's Z Axis towers to do the same for my A1. The scraper mount is identical and also utilizes optional magnets to further secure the scraper from any movement, however this design also includes an additional bracket to be screwed to the tower first in order to slide the scraper holder in place. I used 3M x 6mm screws to mount the bracket, but length just needs to be long enough to thread in. Be sure to use a flat head screw in the top one so its flush with the plastic and the caddy can slide over it. Bottom doesn't matter as I just used a button head there.
Very simple print, no supports. Just print, attach the bracket and slide the holder in place.
3M x (at least) 6mm screws
Ø6x3 magnets - 2pcs (optional)
