Note: The Ender 3 Pro or Ender 3 Plus have a different frame which is not compatible with this model.

Please Read Update 2021: I have not been on Thingivers very much over the last few years. This model is by far my post popular upload, with hundreds of Downloads every day. This drawer design and the various remixes of the same dimensions get downloaded well over a thousand times a day. Unfortunately, there is a very, very small precentage of users who's Ender 3 are not assembled properly, from the manufacturer, which causes fitment issues. This is not a design change by Creality, as some suggest, since the 3 Pro, 3 Plus, CR-10, CR-20 etc are all the same. If your Ender 3 Bed Rollers are not installed with the Nylock nuts on top (See the image with the wrench I added above or Google search any Ender 3 Eccentric Nut Bed Video), you will need to correct this, before installing this drawer. This should be a straight forward process of removing the Bed Heater and Bolts, then reinstalling them in the correct orientation.

This started as a remix of Jayprints Drawer, but now has been completely redone from scratch. I thought it was strange to have one odd shaped drawer, so I split it into two drawers.

I made the case 5 mm shorter, I am including a 5 mm "Spacer" remixed from Tonysix00's Rail insert to leave space for the display cable. Slide it on the Y axis before sliding the main case on, but you may not need it, though.

Update Jan 23, 2019: After some comments and some reflection, I totally remade this drawer from scratch. The new files are not a remix from Jayprints stl, but still based on his design. It should print faster and has slightly bigger drawers. Note that I have not printed the whole thing myself yet. I also removed the jog in the back corner, as my setup doesn't need this. If you want to print the LCD cable clips (which are red in the last image) , see this Thing https://www.thingiverse.com/thing:2960375. The new files are not interchangeable with the old files, due to minor dimensional changes.

Update Feb 10, 2019: As requested, there are now two more versions of the bottom drawer. Version 2 has two small divided sections. Version 3 is a blank drawer, that has no dividers at all. These only fit the New Case.stl. I am also removing the old version of the Drawers, to avoid confusion.

Update Nov 17, 2020: As requested, I uploaded the exported files for the blank Top and Bottom Drawers. (.f3d and .smt)
