Only burned myself 15 times while soldering and assembling the final modified TL902. It does seem to work pretty well. It manages to get over 220F and the potentiometer enables you to select a different max temperature. I used polyamide tape to secure everything in place on the inside. However the side brackets are beginning to melt at those higher temperatures, so attempts will be made to cast from a high temp polyurethane resin instead. See video.
Drew, etched, and soldered the electrical modification board for the thermistor resistance. Was able to do it in less than 30 minutes while streaming, which is pretty quick. 
Rebuilt the laminator using the new side brackets and, although they were not perfect (in reality the lower pin on the motor side bracket needs to be adjusted slightly, though it works as is), and resoldered all the connections after threading the wires through the printed pieces. The motion system works perfectly as intended. See video of it in action. 
Updated design for left-hand bracket per fitment test of previous iteration. Prints should complete overnight. There is no need to actually bond these two together, as they will be clamped together in the assembly. Likely won't need to print/source new gears, as the existing ones seem to mesh fine with the greater separation distance. 
Incorporated design iterations in 43001-002 and divided into an upper/lower half to facilitate printing. 
"Fixed" the printer problem from last night by leaving the lid open. The right-hand bracket does seem to fit all the components perfectly, though the top pegs can be thickened, though they currently match the original part. Designed and printed left-hand bracket piece, without stepper motor standoffs. 
Revised right-hand roller support bracket to improve fitment and modeled left-hand bracket. Left-hand bracket needs mounting holes as well as standoffs to mate with the motor bracket. Had printer issues related to the thermistor while trying to print. I think it's some connectivity problem and am working to fix. 
Began teardown of TL902 thermal laminator for thickness mod and temperature mod. Located potentiometer and JST connector for temperature mod, and began redesign and print of one side of the internal bracket that spaces the rollers apart.
