Assistive Hand Pump for Dispenser Bottles
Setup & instructions
The Assistive Hand Pump for Dispenser Bottles is an assistive device designed to decrease joint fatigue for persons that have arthritic hands. The device decreases fatigue by creating a larger platform for the user to press on. The larger platform allows for both a lower amount of force needed, and a more comfortable position to apply pressure.
Bill of Materials
1 x 3D printed sanitizer mount
1 x 3D printed sanitizer base
Print the assistive hand pump mount on its side (as saved in the STL) at 0.2mm layer height, 20% infill, and with supports in PLA.
Print the assistive hand pump base flat side down at 0.2mm layer height, 20% infill, and no supports in PLA.
To attach the device to the bottle, the end user places the handle of the device over the pump. With the device attached to the pump, the end-user will now have a larger area to press down on, and a more comfortable position with which to press the pump.
With both pieces printed, press fit the two 3D printed parts together in the orientation shown.
This design was created by Yeonjin, Yujeong, and Daeun from Branksome Hall Asia as part of the Make:Able Challenge.
