3d Solutech PLA 1.75mm
I printed with a brim, supports, and extra perimeters in black 3d solutech 1.75 PLA on my Prusa I3 Mk3s.
Use a deburring tool to remove the brim.
Attach screw and magnet
Piece is sized correctly for the screw, but should be careful inserting screw because of layer orientation.
I used Fusion 360 in about 20 minutes.
