Highscoresaves.com Scramble multi-game PCB spacers

thingiverse

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. Another more potentially serious problem is the small board installed in the socket for chip 6E has a nasty habit of coming loose from its socket due to the low number of pins and narrow profile, so I created a shim which when placed on top of it holds it in place with pressure from the board above. I used pieces cut from a 6-32 threaded rod for the screws and two small screws for the corner spacer, 6E's shim simply rests in place and can't move as long as the top board is in place with the 30mm spacers. At some point I'm probably going to go back and refine the corner spacer a little better to allow more room to adjust it in place. Update Jan 21 2019 - Fixed a few annoying little gaps and overhangs in the 6E shim and modified post. They weren't anything that was going to effect the fit and probably wouldn't show up in most prints anyway, but I figured why leave them? I'm thinking that I'm going to design some feet to fit the threaded rod I used (smallest available at the hardware store) since the regular ones use a smaller thread, should be easy enough to create once I've got a pattern for the appropriate sized nuts. Update June 1st 2019 - Added some feet that use nuts for the same 6-32 threaded rod. Hardly elegant but they're functional. At some point I'll probably refine them a little, the shaft for one seems a little oversized.
