This is a tool tray will slide under printer but will catch and stop at the edge of the printer. to keep it from getting lost under the printer. it has 2 options. a hole for a handle and a solid front to add a custom handle. i found and printed a door handle to match my printer. but i left that part up to you. 

this is my first print i made for my needs but i did try to make it as universal as i could .
