Amiga 1200 40mm Fan Internal Holder

I added a scandoubler to my Amiga 1200 which, as usual, sits over the Lisa (and Alice) chips. After the machine was one for a long-ish period of time, I saw graphical glitching and drop outs. It turned out the Lisa chip was getting a bit to warm and I notice blowing air over the chip that the glitching stopped as it cooled off.

I decided to add a small fan into the case but I REALLY hate mods that damage the case. This is designed to take a 40mm computer fan (I used a Noktua as it is reasonably quiet) and fits into the case grill on the underside. From the outside you can't see it at all. I connected the fan by spicing into the FDD power cable and pulled out the 12V to run the fan.

Print instructions

I printed with PETG although PLA should be fine as there shouldn't be enough heat to cause it to deform.
