Wanted a drawer like the one made by Jayjay87, but with these features:

-dont block airflow coming from the left as much -dont let the drawer hit the screw from the tightener -leave space for the cable to the hardware interface behind, then up, without showing a hole -have indentations with sloped sides at the side/top/bottom of the inside of the drawer to reduce friction -have a rail at the top of the drawerholder to stop the drawer going out all the way unless you tilt it, and a matching indentation in the drawer -have a hole where you can stick your finger in, or put a knob of some sort in

note: does not fit on Ender 3 Pro

note: the girders are very tight. You need a hammer and a block of wood to gently tap them in/out.

If you want to make less tight girders: the source file is included, just delete the girders in the holder file and import them back in with shift-f1 in blender.
