This is a little UV resin curing box that I designed, which uses a UV flashlight/torch as its light source. The box is small enough that it can be printed on an Ender 3.
Its designed for a light with a width of 36mm, which sits in a mount at the top of the box. Cover the inside of the box with a reflective material. The door is held on using a large rubber band.
Obviously your flashlight needs to be strong enough to cure the resin. I haven't tested mine yet, as I made this in preparation for my Anycubic Photon.
All of my models are now free!
I've not had much luck trying to sell them, and I can't be bothered anyway. I'd rather have them accessible to the community rather than making a few bucks. If you enjoy my work, buy me a cup of coffee with that donate button!
