Every rechargeable thing deserves a charging stand. This one mounts to the wall, so you might call it a Wahl-mount charger.
This works fine as-is, but it would look better in white, and I kinda want to revise the part that mounts to the wall, so that the cord can tuck underneath it. So it might get updated between now and whenever that spool of white filament lands on my doorstep.
In the OpenScad file you'll see that I made the wall-mount portion 1% bigger, to ensure that the two parts could be assembled. In retrospect I'm not sure that was necessary, or a good idea. But it worked well enough so I didn't bother experimenting with different percentages (or no percentage).
The Wahl mount and the wall mount are printed separately, and held together with an inch-and-a-half #8 screw that comes up from the bottom. I put the pieces together, drilled a hole for the screw using a 7/64 drill bit, then pulled them apart and opened up the hole in the wall mount so that the screw passes through without grabbing.
Insert the charge cord in the Wahl mount, and check the orientation - do you want the lighted charge button to face outward, or do you want it to face the wall? Either way works.
Attach the wall mount with two #8 screws. There are countersunk holes in the mount. I used half-inch screws and no anchors, but I have feeling that I'll need drywall anchors for this to stay solid. We'll see.
Drop the Wahl mount in the wall mount.
Insert the screw to bind the two mounts together.
