I haven't used my resin printer for 9 months because I was getting fed up with everything warping after I printed it.
They were fine when printed but either went dusty grey, warped, or both after a few days so disillusioned I gave up.
I haven't really needed it during that time but now I do so decided to start over. New resin, and I was going to buy a cure wash machine when I saw a DIY article from Kathy Millat and decided to give that a go. I can't bring myself to cut up a perfectly good really useful box so bought a second hand slightly larger one from the charity shop. I will let you know how I get on.

As an alternative suggestion to the really useful box I've seen a metal biscuit tin used as a UV box that has the advantage of having a reflective inner surface to bounce an UV rays back onto the model (seem to recall it was on NGRM-Online).
Nice idea but 'er indoors is very protective of biscuit tins now that they are such a scarce resource in the house.
However I had a bit of luck. The local charity shop was selling a container of wooden "Brio" clone track for £5, so win win. I got the container, grandsons got the extra track. No idea where we will keep it though, they have enough to get from back door to front door now with a passing loop. Unfortunately they get bored before I have finished it and just try running Hotwheels cars on it.
One day I will convert a r/c car to run on it and give it a Loco body!
