There are 3 files:
- an STL with a 5mm countersunk hole
- an STL with a 5mm simple hole
- a STEP file where you can the hole size that suits your needs.
Printed in PLA using a 0.2 layer height, but most likely any setting will do.
For reference - inner dimensions are 55.3x42 mm.
The author marked this model as their own original creation.
