Here we have a wall mount for the Nitecore D4 Battery Charger. The mount gets attached with two 3.5 mm screws (length is up to you), and the charger perfectly snaps in. You need to drill two vertically aligned holes into your wall with a distance of 41 mm (no worries if the distance is slightly off, the screw holes in the mount have been designed with tolerance in mind).
There is a flat version and a tilted version with 10° angle, which in my opinion is more convenient for inserting/removing the batteries and reading the display. The tilted version also has cut-outs for the power cord, in case you want to route the cord downwards.
The SketchUp file includes a quite accurate model of the Nitecore D4 enclosure, which I created for reference.
There is quite a bit of work in this, so if you print & like it, I'd be thankful for a small donation in EUR or USD: https://PayPal.Me/wookbert (or simply use the Tip Button on on the right). Thanks a lot!
As you can see from the attached screenshot that wall mount is standing upright in the print layout. Because of this orientation related to the layers the clamps can't break off. You neither need supports, brims nor a raft to print the mount (given that your filament tacks well enough to the build plate). If you are printing without raft, you might however experience a slight elephant's foot (lowest layers of the print flaring out), which might prevent the mount to properly snap to the charger. Thus minor corrections with a utility knife or file might be required.
I've printed the 10° tilted version on a CEL Robox in ABS with Normal resolution (0.2 mm layer height using the 0.3 mm nozzle) and 13% infill on 3h26min.
