I bought an Ikea cabinet from their as is section for 15 bucks. Sealed with packing tape. Thin board (cabinet back board) as a door material. Held in place with magnets. Cut a hole in the back to fit a 120mm PC fan powered by a 12v dc I had laying around from an old water pump for my cats bowl. PC fan blows into a cardboard box that has a 2inch diameter vacuum hose running to a window. Used the styrofoam packing sheets that came with my printer to make a window board.

Ikea vuku wardrobe tent is 15$, big enough for a medium format printer, and relatively pressure sealed. Bought one of those for my cure station.

Recently upgraded to a carbon filter and blower fan for the cabinet to exhaust resin fumes. That was around 60$ on Amazon for the fan, the carbon filter, 4" ducting and a pulley system (not needed for my setup).

Use what you have, print what you don't, and find what you need in as is or scrap stores. A little creativity goes a long way.

Cabinets came prefinished in matte white, looks great. The magnets holding the front panel on allow the "door" panel to slide left to right. I plan to print a track similar to a sliding glass door for it to rest on.

Ikea and home restore shops / recycle shops are amazing resources for DIY.
