This thing consists of sets of storage boxes for the DJI Mavic 3's Fly More Combo bag.

There are 2 sets of things needed, depending on whether or not you want to store your controller at the top (RC-N1 only), or in a bottom pocket (only option for RC Pro)

Option 1 - Controller stored at top of bag

These are light grey (PLA) and black (TPU) in the photos.

Parts needed:
Mavic_3_Prop_Box_Tray_Lid. (TPU)
Mavic_3_Prop_Box. (PLA)
Mavic_3_Prop_Box_Tray. (PLA)
Mavic_3_Charge_Box. (PLA)

The Charger Box is designed to fit the lower compartment in the Fly More bag, just behind the batteries, and holds the Charging Hub, the Power Supply (only tested against the UK version, but others look similar sized), and the USB-A to USB-C Cable.

The Prop Box is designed to fit the upper compartment, along with the transmitter, and holds the 8 spare props, the 4 ND filters in their case, and the Tray that holds the extra transmitter cables, MicroSD cards, spare control sticks and any other small accessories.

Although not the more efficient use of space, they are designed this way so the charger box has all the parts you probably don't want to lug about on a walk, and can easily be removed and left at home or in the car, reducing the weight. The Prop Box and tray holds all the parts you probably do wish to take with you.

All 8 props are a tight fit in the prop box, and the have to be installed alternating which end the prop tips are, so they sit as flat as possible. Also, pay attention to which way up you put them in, due to extra thickness at the pivot points.

The tray lid is printed in TPU, and designed to be a slight stretch fit, relying on the nature of TPU to maintain a good tight fit that will not accidentally come off. All other parts are PLA.

Option 2 - Controller stored at bottom of bag, behind batteries

These are dark blue (PLA) and white (TPU) in the photos.

Parts needed:
Mavic 3 Top Box (PLA)
Mavic 3 Top Box Charge Box Separator (PLA)
Mavic 3 Top Box Charger Insert (PLA)
Mavic 3 Top Box Car Charger Insert (PLA)
Mavic 3 Top Box Charge Box Lid (TPU), 1 per Charger Insert
Mavic 3 Top Box Trinket Insert (PLA)
Mavic 3 Top Box Trinket Insert Lid (TPU)

All things are designed to fit the upper compartment.

The Top Box holds the 8 spare props at the bottom, and these are covered by the Top Box Charge Box Separator. On top of the separator goes the trinket box (which holds spare SD cards, spare RC sticks, tweezers, lens cloth etc) and one of the Charge boxes, either the one designed to take the UK mains charger and charging hub or the one designed to take the DJI Car Charger and a charging hub. The 4 ND filters in their case slot in the side of the Top Box.

The Charge boxes are designed so you can take whichever charger you will be using, along with the charging hub, or not to take any charging equipment at all by removing the Charge Box from the Top Box. You probably always want to take everything else in the Top Box - spare props, trinket box contents and ND filters.

As is often the case with my designs, the lids are printed in TPU, and designed to be a slight stretch fit, relying on the nature of TPU to maintain a good tight fit that will not accidentally come off. All other parts are PLA.

All Options

I printed the all parts using the standard, supplied "Standard" Cura profile, and used Cura's generic PLA and TPU95 material profiles. These can of course be varied, to create the best compromise between weight and strength to suit you.
