Take your pick (in order of me making them, I really like that you can see the improvement of the plans and of my skill):
The newest dxf is attached. It has some instructions and comments in German, but not too many. The bottom two drawings are the pencil case, the top left is for the inlay/engraving and the left two boxes for the mirrored drawings if doing an inlay to have a border for the clearing paths.
For the pencil cases I nearly exclusively use a 6mm 2-flute, just for the magnet holes I switch because I am a) lazy and b) it’s so much quicker.
The boxes above were made with a 3.175mm 1-flute because I didn’t want to swap the endmills for the two magnet holes. This is connected to the ER collets being pretty snug in the collet and I didn’t want to be bothered taking them out… I ordered another collet so I can easily swap between my most (and so far only) used sizes…
