Oral-B Dual Toothbrush holder - All models

Oral-B Dual toothbrush and charger base holder

This is a wall mountable dual holder for all possible Oral-B iO, Vitality, Genius, Smart and Pro electric toothbrush chargers and brushes. You can choose the right variation for you from six different options, depending on your toothbrush models. Simply select the correct build plate. The holder can be mounted on a wall with 2 screws but works just as well set on a table. You can also easily detach the mount from the wall if you need to take the chargers with you on a trip. The charger wires can be lead neatly from the back either straight down or to the sides. No supports needed. 

A quick rundown on Oral-B brushes and Chargers:

To my knowledge there are 4 types of charger bases in production at the moment. They may have different type numbers depending on the region and production time but at least for me they are as follows: type 3757, two types of 3768 and type 3786. You can check which charger you have from its bottom.

• Type 3757 is an induction charger base with a pin in the middle to hold the brush handle in place. Here is a list of toothbrush models that can use this charger base:
  iO 2- 6, Vitality, Genius, Smart, Pro
• 
   
• Type 3768 is a flat magnetic charger base that comes in two different shapes; one is perfectly round and the other is oval. Toothbrush handle stays in position by magnetic force and it comes with the newer iO models. Both of these bases work similarly and on the same types of brushes. Here is a list of brushes that can use this charger base:
  iO 7 - 10 (but is also compatible with some of the older iO models that have the pin hole)
• 
   

• Type 3786 is flat magnetic charging base with a built in screen. It is rounded and as far as i can tell uses the same body as the round type 3768 charger. It comes with the newest iO 10 toothbrush but should be compatible with all of the older iO models as well. I have not tested the measurements of this charging base and i cannot be certain if it fits on the same slot as the round type 3768 charger. If someone wants to test this be sure to give me feedback, but at the  moment i can not claim that this type fits in this holder.

Models

So now we can get to the model at hand! Based on the different charger bases i have made SIX variations of holders that can fit three types on charger bases. All toohbrush handles that use these bases should fit into the holder. You can choose the right model for your specific need and discard the rest.

Model A / Plate 1: Type 3768 (oval) / Type 3757

Model B / Plate 2: Type 3768 (oval) / Type 3768 (oval)

Model C / Plate 3: Type 3757 / Type 3757

Model D / Plate 4: Type 3768 (round) / Type 3757

Model E / Plate 5: Type 3768 (round) / Type 3768 (oval)

Model F / Plate 6: Type 3768 (round) / Type 3768 (round)

The brush handle holes are spacious enough for easy access, but the slots for the charger bases are optimized for tight fit. Be sure to slow down printing speed on overhangs to reduce sagging on the front/upper parts of the charger slots to ensure they fit nicely.
