Qube 500 Filament Dryer & Spool Holder

Idea I have been toying with for a while and this seems to be the perfect application to test.

Aim is to use waste heat from the PC to dry out old filament, would need some experimenting to get the temperatures right but most mid range PCs doing light to medium work loads should put out around 60deg top air temp. 

If you have a a i9 and 4090, then could be used for higher spec filament, again some one will be able to get a YouTube video out of this….

The housing is designed to line up with 2x 120mm exhaust fans, with the top cover holding a generic Amazon temp/humidity gauge.

Everything can be printed without supports, but I would suggest using a higher grade material for this for to avoid deforming if your temps creep too high, you will need to monitor temperatures carefully when drying filament.

The body is a big print (240x205x130), as it needs to hold a wide variety of spools.

I've updated the design slightly, to save on material and reposition spool holder as it was hanging low. I did some quick testing, looks like it is dropping around 10% humidity at 37.4C. 

It would be interesting to get the temperature higher, the cooling set up in my PC has multiple exhaust locations, if this was the only exit, I would expect higher temps. 

I made all the parts out of PETG, so I shouldn't need to worry about temperatures getting too high.

Any feedback welcome to help refine it.

Thanks!
