Watercooled Peltier-Cloudchamber

I built myself a watercooled Peltier-based Cloud chamber, because I had an AIO Watercooler for a PC laying around.
In my case it is an Enermax III Liqmax RGB with a 240mm Radiator. The radiator is screwed in with 2x M3.5 screws along the support beams, it holds up very well and does not shake or anything.
Obviously you will need some stuff from the hardware store, in my case a M4 threaded rod that I cut to the right length, corresponding washers and nuts. The hole pattern I used to correctly align the 3D-printed parts with the waterblock was the AM4 standard.

The soldered "electronic" part is all internal in the space under the pump-block. I used pin-strips to connect the fans and pump to 12V (as I did not want to cut the cables of the AIO. This also would enable me to use it again in a PC build if I ever wanted.).
Main power for the Peltiers (3 stacked, a "TEC-12709" that is getting 12V, and 2x "TEC-12706" that are recieving 5V and 3.3V) comes from 3x4mm Banana-Sockets and leave
