sparkmaker ext fan mount

My stock 50*50*10 fan die on me.. so come out with an idea to make a external fan mount .. it work well enough ...

it just a clip on design.. one may want to use some blue tack to seal the gap or edit the stp file, as it not design to fit 100%.. too lazy to make it 100% fit.. this will accept any 50mm*50mm* xxmm DC fan..

got the idea from https://www.thingiverse.com/thing:2797214
