I made this little tool holder that fits in the bottom front left of the printer. It mounts on the inside and the drawer slides in. The knob and the drawer itself go together with the standard nut and bolt that you used for assembly. the first time i printed this, it was off by a few mm so i adjusted the files and uploaded them so they should be good in terms of size. i did not reprint mine i just cut a bit off the top so i didnt test it but i am sure it correct! if you need anything along with these files let me know

Printed it with abs and .2 layers 50% infill I think. Took forever to print! note the edges will warp if you dont have a solution for that, and it may cause the dimensions to be off in the end for an imperfect fit.
