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].
Cheers -lev
