I redesigned the “BambuLab A1 Mini Plate Holder” by wszqmrg4vk.
I increased the width of the tree slots to 1.2 mm to easily accommodate the thicker Smooth PEI Plates.
I found that the original model was even too tight for the Textured PEI Plate, which isnt a problem anymore.
I added a voroni version just to try it.
The model is printable on the a1 mini when turned 45°.
If you want to change the plateholder yourself you cant use the f3d files i attached.
