case for DC-DC boost converter without fan

thingiverse

I hacked together a customized version of a similar box with fan to meet my specific needs. I used to juice up my portable 36V e-bike battery in a public library, requesting a super quiet charger - the original charger with fan was just too loud. By the way, I'm using an adaptor converter so that I can charge my battery using my dell laptop charger (65W). It's been thoroughly tested and I'm extremely happy with the results.
