The prosthetic arm was 3D designed and printed. It consists of three main parts:

• First Part: Forearm
  • Covers the majority of the forearm
  • A customized opening on the top to avoid discomfort and pressure on user’s lump
  • Two attachment mechanisms to allow for multifunctonality of the prosthetic

• Second part: Upper arm
  • Inner padding (silipos gel dots) to add comfort and grip to the prosthetic  
  • Weight and force distribution from forearm
    to upper arm

• Attachment between Upper arm/ Forearm: 
  • Preserves comfort, facilitates weight distribution, and helps reducing strain on shoulders
  • Elastic straps and circular strap attachments, elbow motion dependent
  • Adjusters used to easily change fitting
  • Bottom straps to add grip and help with weight and force distribution

 

• Third Part – Attachments :
  • Bow Holder Attachment:
    • Screwed onto the forearm part for stability and strength
    • Adjustable bow attachment part that accommodates different bows
    • Two screws to control the rotation of the bow and lock it to the desired angle
    • Tilting mechanism to have the hairs of the bow in complete contact with violin’s strings
      
  • Bike Handlebar Attachment:
    • Wrist joint motion for a flexible control of the bike’s handlebar
    • Shock absorbance to minimize possible injuries
    • Velcro on the inside for grip with the bike’s handlebar
