This is a double set of drawers for the ender 3 pro. Its designed to used the front space after doing Teaching Techs all in one case https://www.thingiverse.com/thing:3688967 The Right side will fit with the factory case but there are lots of other designs for that. I've included the step file for anyone that wants to change the dividers in the drawers etc. The left and right drawers are the same and either of the uploaded will work. It has a recess for a 6mmx2mm magnet in the back for retention.
I added the Left and Right Case for the Standard Ender 3. There is a gap of 10.2mm between the y axis rail.
The top drawers are different between the pro and non pro versions To clear pan head screws on the Yrail. You may have to replace the cap head ones on the belt tensioner.
PROTIP!! I highly recommend pausing the print after the pockets for the magnets are printed and install them at that point with a drop of CA glue. It is possible after the print but its difficult.
Supports are needed for the handles. Its a minor amount of print material. Its a tight fit in the extruded rails and that's what I wanted. It may take some persuasion depending on your printer.
