Hard Carrying Case for NOCO GBX75 Battery Booster

Hard case for NOCO GBX75 battery booster, including optional company name on top for 2 color print.

Adapted from Nibb31's Frog Box (thanks for providing the Fusion 360 files), with the latches from Rambelaya's remix. 

The lid features the NOCO name, the bottom is shaped to hold the booster, plus a compartment for the charging cables. 

The size of the booster makes it impossible to print this on a smaller printer, such as Mk4 or Core ONE. Dimensions are 290 x 194 x 43 mm. You'll need a large volume printer such as the Prusa XL. 

Fusion f3d file included (I didn't sanitize Nibb31's original approach, which was a bit “rough”). 

BOM

8x M3x20mm hex bolts or screws.

Printing

Print 1 copy each of lid and bottom, 2 hinges, 2 latch arms, and 2 latch cams.

To survive in a truck or car, use PETG, ASA, or PC-CF to print the model. I used PETG for the actual case and ASA for the hinges and latching mechanism. I printed it on an XL with textured sheet, 0.25mm structural profile, 4 perimeters, 15% cubic infill.  See 3mf files.

The lid.stl file can be printed as is, or you can use Split to Parts in Prusaslicer to break out the company name and print it in a different color. See lid.3mf file for details.

BTW, the font seems to be Universe Black. Which of course wouldn't extrude in Fusion so I fixed it in Inkscape.

Assembly

Use 4 M3x20 bolts to secure the hinges in the back. Use the other bolts to secure the latch components in the front, with the larger side of the cam facing outward. See video in the original Frog Box post https://www.thingiverse.com/thing:4094861 for details. No nuts required.
