Multiple drill bit / punch / countersink / plug

I needed a block with various sizes of holes for holding different sizes of bits/objects.Couldn't find anything which was suitable so I created this. 210mm long, 80mm wide and 25mm tall, holes are 20mm.Holes are 4-10mm. If you want them tighter then lower “XY Hole compensation” - currently it's set to add an extra 0.5mm radius.
