Building Ronja Led Holder

We are going to drill 4 metal strips. These strips will be assembled together using 2 M3 bolts, 10 M3 nuts, 1 M6 bolt and 1 M6 nut.

There are two possibilities how to drill out the box. First one is using a calibrated printer, printing out a template and gluing the template on a tin. The second one is measuring everything by hand.
