Hello BR, Sorry for the late reply, been on vacation. Also thank you for the compliment on JBox
The physical overall size of the box is 59 inches tall 36 wide by 22 inches deep. I think if a build a another one I would cut the depth to 20 inches deep. This would then give you some spare wood veneer to work with as it was, I only had 4 square inches left out of a 4 foot by 8 foot veneer sheet. No room for errors.
As for the tubing I used, I ordered 1" I.D. ,1-1/4" O.D. inch Semi-clear High-pressure/Vacuum Polyethylene ( Part number 50375k59) from Mcmaster-Carr. If you are planning on constructing a JBox please post pics. Love to see others. Also happy to share arduine programing code for led tubs when you get that far, although I'm not a professional programing by trade. Its only a hobbie for me. Also, I have some rough looking circuit diagrams I used and could try to post here if you need them.
