Ender 3 V1 box case

Remixed original to fit Ender 3 V1 (not Pro!) (https://www.thingiverse.com/thing:3416444)

Changes:

* Length shortened by 5mm
* Top box support extended 10mm left to fit Ender 3 V1
* Top box height reduced by ~5mm to allow bed rollers move

You can use bottom box from original thing with minor correction (reduce length by 5mm)
You can't use old top box enitely, too many changes. Important: empty space on top left corner of box is necessary.
