And to cover the top of the printer - One of those boxes that holds paper is the perfect size in all 3 dimensions. These boxes are from office supply companies like stapes and are sitting around near photocopy machines at work. Tape it to the top of the UM2 and there will be a nice gap in the back for the bowden to move around. With a front door and a top, and with the bed at 100C to 110C you will get an air temp of around 40C which means your ABS will shrink half as much as normal during the printing phase (and then shrink the second half after printing is done. This is now similar to PLA.
PLA shrinks about .3% from glass temp to room temp (60C to 20C). ABS shrinks about .6% from glass temp to room temp (100C to 20C).
