Highscoresaves.com Scramble multi-game PCB spacers

This is a set of custom PCB spacers designed for Highscoresave.com's Scramble multi-game adapter kit, it contains 3 30mm spacers, a custom corner spacer and a shim to hold one of the smaller boards in place.

For those unfamiliar with it it the design doesn't allow for the usual support spacer in one corner of the normal two-board stack because one of the kit's PCBs protrudes and doesn't have a hole to pass a screw through, so I designed a 30mm high spacer which basically wraps around it. Ano
