I was in the sofa the other day and I couldn’t reach the TV remote control, and as I have a broken leg it was very boring to get up, take the crutches and pick it up. So I decided to make an extra hand for my crutches.
Step 1: Print the Parts
Design in a CAD software your model.
Some things to take into account:
-The diameter of your crutches. Use a semi cilinder in the base for better adjustment.
-Big radius pliers, in order to pick up large products but allow the top part to go inside the other for pick small ones.
-Three holes: one for the axle, and two for the spring and cable. Try to put it as far as you could for higher torque.
By the way, I attach the .stl files.
Step 2: Fix It to the Crutches and Final Details
Use an old bike inner tube for better grip.
Use a screw as an axle.
For keep the pliers open you can use a spring or an elastic band.
For pull down the pliers use a nylon cable.
Step 3: It Works!
8166 made it!
