Hydroalcoholic dispenser (liquid dispenser)

thingiverse

Using 10 mm rubber tube, one spring and six 3D-printed parts, a functional liquid dispenser is now in development. Any water bottle can be repurposed as the tank for this dispenser by adding a hole to the top of the bottle to allow air to enter. A hole must be drilled into the bottle cap, which is then glued onto one of the printed parts. The spring's location will need to be adjusted according to its strength. The assembly utilizes M5 and M3 screws.
