DJI Mini3 Pro "Snug Box"

Following the suggestions of user [Wichiman](https://www.thingiverse.com/wichiman/designs) on Hardcase for the "DJI Mini 3 Pro" by dagerber, I'm making a remix of that thing.

My modifications include [the references to original design in brackets]:

- +0.5mm inner space in all X- and Y-directions [was very tight]
- Less ovelap of bottom and top: 5mm [10mm]
- Chamfered transition in top part to overlap portion. No supports needed. [supports needed]
- Embossed DJI logo added. 0.2mm deep so use max 0.2 layers at least until 0.2 mm height [no logo]
- More nimble locking mechanism [a bit overkill IMHO]
- obj-format for nicer, non-segmented arcs [STL]

Have already printed two of these: One for me and the other for my friend.
