I wanted to design a sheet holder that matched the style of the printer. It can hold 4 sheets and locates them using the rear tab. This way the print easily fits on the bed.

Print in a material of your choosing. I’d just recommend 3 walls for sufficient strength.

Designed for the X1 Series and P Series. Not sure if it's compatibe with the A1 mini but the sheets should fit. I don't have one yet to test.
