printed well on a1 mini. can't comment on how well it works as the mounting brackets are too thick and do not fit under my scope. not a design issue but mentioning it so anyone else printing maybe reads this and double checks before printing for themselves. if the designer is making upgrades, it maybe nice to have the outer wall of the catcher be a latching door so you dont have to remove the catcher to empty the bin or even a half latch to give easy access to an extended charging bolt.

Printed awesome on A1 Mini
