CTC cooling fan bracket
thingiverse
I fixed my printer because it kept failing on a sweltering day and the fan inside wasn't blowing enough air to keep it cool when running. You can repurpose the 2 bolts and nuts from the old fan. To install the new fan, you'll need to drill two holes in the wooden bed. Just be careful not to damage the circuit board when drilling the holes and make sure the power is off. It may hum a bit, but that depends on the fan you choose. https://www.ebay.com/itm/50mm-5cm-DC-12V-0-12A-Blower-Turbine-Centrifugal-Cooling-Fan-High-Performance/222324886362?hash=item33c3988b5a:g:L~8AAOSwHJVbRBS5
