This is a remix of "Ender 3 V3 KE/SE parts by tumad":

I didn't like some aspects of the boxes:

1. With the original design, they could rotate outwards and then fall off the gantry. Now they feature the gantry clips from cheesmac's design. You best attach them to one side and then give it a firm push until the other side snaps into place. Once it sits, it stays.

2. The left hand box printed with a hole, where the cable guide should attach. I used the other half of cheesmac's clip to fix it. While I was at it, I also added a mirrored version of hapedevee's tool holder.

3. The right hand box interfered with SMASH3Dcwb's camera mount. I made that one flatter, so it still fits below the mount. If the gantry is in its lowest position, you can still open the lid.

4. I also added a mirrored version of the lid, as some users asked for it in the comments of the original thing.

SMASH3Dcwb's camera mount and turbox_3's screw were added for your convenience. As my Nebula cam is still waiting in the warehouse for me to order it, I used a phone clamp as placeholder. Should I also buy the input shaper, I might edit the camera mount at a later point. I can't promise or give you a timeframe, though.
