I designed this drilling jig to assemble my BESTA cabinet doors on a METOD cupboard.
Align the end of the jig with the end of your cabinet (your cabinet door ends here). There is a triangular cutout to mark the middle of the hinge, so it's easy to measure the required distance to the next hinge (and according hole pattern position). The holes are designed to use threaded inserts (M4) to maximize the durability of the drill guides.
