Focbox baseplate drill jig
Description
This is a jig to help drill accurate holes to match the focbox mounting holes. The drill hoes are 4mm. I used a 5/32" drill bit. Focbox baseplate has holes threaded for M3. I bought M3 countersink screws on amazon. Most of the ones that come in a kit have a 90 degree countersink, so I also purchased some generic 90 degree countersink bits. The triangles are at the reference edges -- the focbox baseplate will line up with those edges. There's a row of holes to help with calibration. 3, 3.5, 4, 4.5mm. You should be able to drill out at least 2 aluminum plates before the holes are too wallowed out. STEP files included if you need to make adjustments.
