Bionaire 611D reusable filter housing

Reusable filter housing meant to replace the now hard to find Bionaire 611D filter. There's a full, and split versions available, as the filter is too big for efficient printing on small printers like the Ender 3. However, if you have a large enough printer I recommend not faffing with the separate pieces.
Additional note for those printing in pieces, I recommend adding a bit of reinforcement to the glue joint with the superglue and baking soda method to give the model extra strength.

There is an optional hole on one side of the body for a small pulltab to aid removal, you can use any 2cm strip of material for this, I used an old lanyard.

For filter material, you can find generic pleated HEPA filter sheets on Aliexpress and Amazon, which can easily be cut to size. Activated carbon sheets and similarly be found online or at your local home improvement store. 

I used 3 layers of Hepa filter, as I didn't require deodorising, these were secured using small pieces of double sided tape to the inside of the body.
