I had no problem printing with PLA and these settings
Infill: 30%
Support: Tree
Walls: 1.2mm
Brim: YES!!!
I rotated like this to get it to fit on the bed
I could only make it fit 6 Gridfinity squares without going off the bed, so there's a CM on each side to do whatever you want.
You will need longer screws to attach it to the printer
Thank you so much.
