Another update: Big gloves exist on eBay. So easy peacy lemon squeezy. As soon as I've moved into the new apartment with the garage, I should have this glove box done in no time. Right now checking with Leon and Pavel whether there's an alternative to the UV LED matrix which isn't frigging expensive. I'm not willing nor am I able to pay 4150 USD for a chip in a prototype, especially because of the fact that I know that the first few attempts of making a PCB might go up in flames.

Hi So I'm a bit further in the planning phase, and it's now a fact that you can build a pretty good inexpensive closed loop system with a very low budget.
For blowing the air up from the bottom and in order to suck it in at the top, I'll order a box of those cheap CPU chasis fans here: https://www.cclonline.com/product/277876/N51QT/Chassis-Case-Fans/Maplin-80mm -Black-Chassis-Fan-with-3Pin-4Pin-Male-Female-Connector/CLR1965/ The air duct can be done with... well... an air duct... https://www.ebay.ie/itm/Aluminium-Flexible-Hose-Alloy-Air-Duct-Tube-Flexi-Pi pe/254900078406 The perforated aluminum sheets are cheap as hell as well... https://hardware-warehouse.co.uk/Round-Perforated-Anodised-Aluminium-Sheet-1 mm-1m-500mm-1mm So are the HEPA filters: https://www.ebay.ie/itm/AREBOS-Hepa-Filter-Staubsauger-Geeignet-fur-Industri estaubsauger-1800W/184489133876
The only difficult part, which isn't cheap and easy available for sourcing is the globes for the glove box, so I'll probably have to find a way in order to make that myself somehow...

Hi So I'm right now tinkering together the GloveBox in FreeCAD. Attached is a little preview. Material wise we're much cheaper than the alternatives found on global supply[1], since I'm using standard aluminum profiles, acrylic glas and other off the shelf materials like perforated aluminum sheets[2], and for the air filtration I will use an inexpensive pump with HEPA filter from eBay[3].
