1Measure the dimensions of the arm.
Measure the circumference of the arm at two points between which the prosthetic arm socket has to be attached.
2Cut the Thermoplastic Material.
Mark and then cut the Thermoplastic material as per the earlier measured dimensions.
3Heat the Thermoplastic Material.
Use a heat gun to heat the sized Thermoplastic material until it is malleable enough to apply.
4Moulding the Thermoplastic.
A. Firstly prepare the arm on which the prosthetic by putting insulating material on the hand.
B. Then slowly apply the heated plastic on to the arm.
5Attach the 3D printed wrist part.
A. 3D print the downloadable file available in the files section this project.
B. Mould the Thermoplastic over the slitted part of the wrist.
Let the Prosthetic Arm cool down to Harden up and keep its shape.
Not everyone's arm is the same and so for that very reason we may need to adjust the form of the prosthetic to fit it perfectly.
8Add the Straps.
Add the Velcro straps according to the Prosthetic arm and the arm of the end user.
