So I work as the Tech Director at a public school (USA) and we are 1:1 with Chromebooks for grades 3-12. This is great except that only 6-12 take theirs home which means that 3 grades of classrooms have to have a way to charge and store their Chromebooks. We started with carts, slotted organizers, I think one teacher even used a dish rack but they all had the same issue, busted plugs and damage to the device (usually the keyboard) from students hastily jamming them into place.
Now I find myself with this high precision laser, a bunch of draft board from a canceled project, and a set of calipers. Since I couldn’t FIND a solution, I MADE one. Well several actually cause each is specific to the model of the device.

Here you can see how the plug sits in the lowest plates… sort of.
Each docking station is comprised of layers of Thick Draftboard and topped with a single layer of
clear acrylic (not pictured). Size tolerances are tight enough that it just barely squeezes the device so it always hits the plug in the bottom straight on to prevent damage.
All cables are ired at the back and pressure locked in place to prevent damage from yanking, moving, etc.
The top layer of draftboard is etched with student names so that the same student gets the same device everytime (in theory).
Held together with 2 sets of screws the top layers can be removed by the classroom teacher without risking rewiring the entire kit.
Additional layers of thickness provide additional support in lower (rougher) grades.
Since the entire thing is the solid material the weight does a fair job of preventing slip, but rubber feet can be added to the underside for more grip.
Made for Lenovo N21, N23, HP 11 G6 EE, and Asus C302C (files in the laser designs section)
