This week I have been printing a ton on my UNIZ Slash SLA printer, and if you aren’t familiar with SLA you need to cure the part in a “UV oven” post printing. While many folks just use a fingernail polish curing box, those provide small quantities of UV light, and the slash does not work at the traditional 405nm wavelength but rather 395nm. So I decided to build my own high-power curing box. Starting with a virgin pain can, I obtained a 30W 30VDC 395nm LED panel with lens and integral cooling (this thing gets insanely hot). I was going to drill the lid and then use a hole punch to cut though for the lens, and then said “Hey, I have a Glowforge!”. I decided 
maple would be good, since the resin ends up dripping on everything and this way with the finish it would be easier to clean. I used wood rather than acrylic since I wanted it to be opaque at UV to protect me (this is super bright). So it turns out a paint can lid is 6.25 inches in diameter and the little rim underneath is 0.25" thick. So a couple of circles later and some CA glue. And we are curing! And amazingly the UV light shines pretty well through the plywood!
Eventually I will put a small battery powered turntable on the bottom with a mirror and I have 395nm LED strips to wrap around the inside of the can.
This isn’t suspicious looking at all…
