I took the original model, and modified it for my own needs. I moved the charger to the middle, so that the toothbrushes sit further apart, and to give it a more balanced look. I also added more drainage holes in the bottom of each storage location for better drainage/less chance of mould.
The charger is a firm press fit, so it stays in place. Toothbrushes easily slot in and out without any force, but are still securely held in place.
For cable storage, I just cable tied the power cable underneath the holder, so it's practically out of sight. I stuck the holder to the wall using good quality double sided tape. (make sure to clean the surfaces with isopropyl alcohol first!)
I also added 4 toothbrush version on request. I haven't printed this myself, but it should print just the same as the 2 toothbrush version.
The author remixed this model.
I've modified the layout/order of toothbrushes and charger, added more drainage holes, and added a 4 toothbrush version.
