I designed this holder for my Braun shaver. It has a slot for the cleaning brush, a hole for the charging cable, and a way to store the excess cable for the charger inside.

I only printed the v2 model. The hole for v2 was slightly too small so I just sanded the plastic of the charger a bit. The v3 STL has a slightly bigger hole that is .15mm larger let me know how it goes if you print this. The hole is designed to be a tight fit so you can take the shaver on/off with ease. Fusion 360 file provided if you'd like to make adjustments.

I tapered the insides, so it should be able to print without support, but I added a support enforcer to the bottom of the slot for the brush. It's the green box in prusa slicer in one of the images that you can see.

Printed with a brim (not a raft) since the bottom of the print is mostly hollow.
