Hesine M505-B Fan intake/outake enclosure

thingiverse

I found the heat on the board was getting to be too intense, so I added two fan duct systems - one to draw in cool air and another to exhaust hot air from the main board - to circulate air around the wires and prevent overheating on the board. I had a fire on the board which was fixed, but it could have been user error - that's what I'm about 90% sure of. To address this issue, I designed an attachment for my enclosure that gives the fan enough space so it's not too close to the 3D printer and not too far away that it has to work hard. The last picture is of a high-temp alarm board which has a temperature sensor that works great. I'm planning to use this board on other projects in the future because it's been working well on my current project for over a year and has logged more than 22 days of total print time. In the future, I'll likely make some changes to this design by adding mounts for screw holes and an insert mount between the material. On the bottom piece, I simply inserted the main board and marked the holes before drilling them out - it worked great. However, I would definitely include screw holes in the next version, as well as possibly a better enclosure.
