It should be loose so you can slide film in/out.

- Light proof lid, can fill tank in ~8 seconds, empties in ~6 seconds.
- Uses TPU seals, print in soft TPU for good seal (tried with 95A TPU, does not work)
- Uses 2x M3 threaded brass inserts and 2x M3 40mm bolts for the latches
Might be better to use silicone for seal.
