Caution: Before going ahead with printing, check if by any chance the screws/bolts holding the bed rollers/wheels for the y-axis may hit the drawer case or not. Apparently, Creality has changed the size and orientation of these screws. A few users have mentioned having problems with those screws colliding with the case. If this is the case, diegoav9 has made a remix of the V2 drawer case where he made a slot for the bed roller screws to pass.

If you have any other design suggestions about how could this problem be resolved, leave it in the comments. I'll try to fix it. Meanwhile, the STEP file is available in the files section, if you want to change it yourself. Remember to add a remix on thingiverse.
Although 90% of the people who printed this did not have any problems with fitment but I strongly suggest you check the dimension of the case form the STEP file before printing it so that you might not end up wasting filament because of some design change that Creality make in future.
This is based on Littlefiver's Ender 3 Double Drawer, but now has been completely redone from scratch for Ender 3 Pro. This one will not fit in Ender 3.
There are pockets to insert magnets in the drawers and the case (as locks for drawers). The pockets are designed to accommodate round magnets of size 8x3mm. You can also use any smaller sized magnets in those pockets. But if you don't want to insert the magnets then its upto you. The drawers will fit perfectly either way.
I made the case 5 mm shorter to accommodate the LCD ribbon cable cover. I have printed Sparky277480's LCD ribbon cable cover for my printer.

You can print "LcdRibbonCoverA_V2.stl" for Ender 3 Pro since the other part "ribbonclipelbowshort_v1.stl" is not yet compatible with this drawer. But I am working on a remix of that one too, to be able to be installed with this drawer. Meanwhile you should only print "LcdRibbonCoverA_V2.stl" with this drawer to cover the LCD Cable.
If you are upto some handwork with this design then you can print both the parts and then clip them with the cutter pliers to fit with this Drawer.
You can also install the Ender 3 Cable Clips with this, instead of the LCD ribbon cable cover

Share your makes and remarks.
Update 12.04.2019: I have corrected the orientation of objects in STL files. Now you can print these with the same orientation as in the STL Files.
Update 05.05.2019: Based on the experience of inuit, it is recommended to scale down both drawers to 99.5% if you are not sure about the calibration of your printer.
Update 02.10.2019: I have added the STEP file for the assembly. Feel free to remix it guys. Do share your remixes here.
Update 17.06.2020: I have aligned the drawer pull knobs as requested by Roger5555. Now both drawer handles are aligned. If someone needs to reprint, bottom drawer is the one that has been changed. Top drawer is the same. Moreover, I have removed a lot of material from the Case after seeing that suggested in a remix.
The recommended files to be printed (if you printing it for the first time) are:
Drawers_Case_v2.stl
Bottom_Drawer_v2.stl
Top_Drawer.stl
