Liquid Cooling Water Block
thingiverse
A simple direct-contact water block, with 1/4" hose barbs, originally designed for "60w" thermoelectric coolers. This device puts the water in direct contact with the object to be cooled, so don't use it for CPUs or really anything valuable. Requires a seal - I designed the gland to fit a 218 silicone O-ring (McMaster-Carr #1283N91); it seals really well that way. However, you could just cut a seal out of neoprene or something, or use gasket maker to seal it up. FreeCAD design's included.
