This stand will support a TOPTON n100 firewall to allow you to place a standard 80mm PC fan underneath for cooling. I specifically made it with these AC Infinity fans in mind since they have silicone rubber feet and external USB power but you can use any suitable fan you want.
TOPTON has several microPC models and the specs vary somewhat so if it looks like the photo, it'll probably fit. There are two designs, both for a firewall measuring 126mm x 134mm.
The v1 model can be printed with no supports and has no index pins. It uses a lip to keep the firewall in place.
The v2-v4 models will index into holes in the bottom of the case. The sides are flush with the sides of the firewall. You will need supports for the index pin outcroppings but you probably won't need them for the angled slots or the hexagons. The Voronai Edition will probably need many supports. I like the design, but it'll be a challenging print.
There should be adequate clearance on all designs so that you don't have to remove the rubber feet from the bottom of the firewall, and the slots are wide enough to pass the fan's USB power connector
You should be able to print in either PLA or PETG with 10%-20% infill. I recommend PETG as my TOPTON runs at 44C-64C (depending on whether the fan is on) and PLA might start to sag over time from the heat.
