One of the key recommendations of the World Health Organization is regular hand washing and disinfection.

In the shop, in transport, at work you can disinfect your hands with a bottle of antiseptic, but it is not always possible to get it out of your pocket or bag quickly. And there is always a risk that viruses will remain on the vial or the clothes that store the vial. As for the stationary hand sanitizer dispenser - they are not installed everywhere and you need to look for them.

Our hand sanitizer dispenser is designed to disinfect hands as quickly and conveniently as possible, so that a person can disinfect their hands after each touch of potentially virus-contaminated surfaces, thus reducing the chances of virus transfer and infection.

The latest version of the disinfector is available on our website, you can read about previous versions at instructables.com

In the new version 1.1 we changed the location and volume of the container with antiseptic, as well as changed the design of the clamp, using instead of aluminum clamp, a plastic insert in the bracelet made on a 3d printer. 


 Instruction ver. 1.1:

We're going to need materials:

Binder clip, size - 19mm(0.75 inch) 1pc. and binder clip, size - 32mm(1.25 inches) 1pc.


Silicone thick-walled tube


Xiaomi mi band 2 Strap Belt Silicone(In this case FitMaster2)


Bracelet insert printed on a 3d printer (3d model download)


Silicone Air Tubing for Aquarium, length 1 meter, diameter (internal 4mm./ external 6mm.)


2 Connectors, connect standard Air Tubing for Aquarium


Antiseptic tank - empty Doy-pack packaging


Several important parameters of the Doy-pack you are using: 

- Doy-pack volume in the area of 0.5 liters (in the range of 0.3 - 0.6 liters).

- lateral arrangement of pour spouts (to reduce tube bend)

- Quality spouts (without turning the cap after closing), spouts can be of several types (sizes), it is worth choosing with an internal diameter of 10mm or more.

- Due to the aggressiveness of alcohols, it is desirable to use Doy-pack for household chemistry, in which chemically active products are packaged: shampoo, soap, washing powder, etc. As a rule, their inner layer in contact with the filler is made of high density polyethylene, which guarantees the resistance of packaging to alcohol (in the disinfectant solution).

We're gonna need some tools:

Assembly of the tank:

We're rounding up the sharp corners of the Doy-pack. With the help of a puncher, drill or soldering iron we make two holes in the bottom part of the pack (in the area of soldered layers of the Doy-pack) for fixing the shoulder belt.
