minifix jig

I was making a case for may Prusa i3 clone and choose MDF to make it. In order to put it together i used this jig to make it easier to match the holes for the minifix eccentrics and it worked quite good for a dozen of holes ( probably not gonna last much but i didn't see any wear). Printed from ABS, probably gonna work with PETG and PLA as long as not overheated during drilling.
Some other tools are needed of course:
