These are a pair of storage boxes designed to store the additional small parts that come with the DJI (Mavic) Mini 2 Fly More Combo.

The Prop Box fits under the charging hub in the Fly More case, and holds:
1 x Prop Screwdriver provided by DJI with the Mini 2
2 x Unused USB<>Phone cables (Lightning, USB-C, Micro USB) provided by DJI with the Mini 2
3 x Spare Prop Pairs, with screws, provided with the Fly More Combo
2 Controller sticks provided by DJI with the Fly More pack
2 x Spare MicroSD

Charger Box fits under the controller, and is designed to hold:
1 x UK USB Charger supplied with the Mini 2
1 x USB to USB-C cable provided with the Mini 2 and the Fly More pack

The boxes purposely has a lip around the top of the open areas, this helps keep the USB cables and other items in place in the box.

The Prop Box lid is TPU, and is designed to be a reasonably tight fit, relying on TPU's flexibility to hold it firmly in place. The charger box has no lid.

V3 and V4 of Box 1 mostly only differ in the the depth of the lid, with V4 being a deeper lid, which works better if printed on a resin printer.

The Charger box is for the UK charger. There is an EU version made from dimensions provided in the comments, and photos from a European member's print.

Resolution and Infill will be down to preference - it doesn't matter. Prints equally well on SLA as well as traditional FDM printers.
