I designed this chamber to be able to hold more/larger resin prints for curing.  The lid is designed to hold a 20W LED UV light I purchased off Amazon, with the light's rough dimensions being 3.5" x 4.5".  It is meant to be lined with a reflective material of some sort, such as Aluminum HVAC Tape.  The two braces are meant to be glued in place to support the print better, although they may not be necessary.  In the pictures I had not yet finished lining it with the tape.
