Assistive Music Device

thingiverse

Hello! For my senior project, I designed devices to assist people in playing musical instruments. As seen in the attached pictures, the device has a modular base that allows it to be paired with interchangeable drumstick, xylophone mallet, or guitar pick holders. The device straps onto the user's forearm, ultimately assisting those with limited grasping ability in their hands to experience the power of playing a musical instrument. General Info: Extra Materials: * M5 Screws: 2 x 12 mm screws for base/plate connection * 1 x 12 mm screw for drumstick and xylophone mallet holders as set screws * 1 x 16 mm screw for guitar pick holder as set screw * M5-0.8 Hex Nuts: 2 per base/plate, 1 per holder * Velcro: 0.75 in. or 19.05 mm wide straps (2 per device) There are three sizes of the device available from the files above, determined by the width of the middle of the user's forearm laid on a flat surface. Small Plate for Prosthetic (Small Size): up to 4.32 cm or 1.7 in. Plate for Prosthetic with Fillet (Medium Size): up to 6.35 cm or 2.5 in. Large Plate for Prosthetic (Large Size): up to 7.62 cm or 3 in. All designs include a fillet; these names correspond to the given files. There are also three types of drumstick holders, with standard size charts available for most brand name sticks. You can measure your drumstick's diameter to find the best holder for you. New 0.59 inch Drumstick Holder (1.5 cm in diameter): fits sizes 5A and 7A New 0.63 inch Drumstick Holder (1.6 cm in diameter): fits sizes 1A, 3A, 5B New 0.68 inch Drumstick Holder (1.7 cm in diameter): fits sizes 2B, Rock The Xylophone Mallet Holder will hold any mallet with a diameter under 0.5 inches or 1.27 centimeters. The Guitar Pick Holder will hold most standard guitar picks. Total Time for Completion: Drumstick and Xylophone Mallet Holders: around 1.5 hours Guitar Pick Holder: around 1.5 hours Small Plate for Prosthetic: around 2 hours Plate for Prosthetic with Fillet: around 3 hours Large Plate for Prosthetic: around 4 hours Printers are not uniform across brands and models, so the heights and percentages may vary during your print. The goal is to have the hex nut encased by the print, so use your best judgment as to when to place it in the design. Post-Printing: For Drumstick, Xylophone Mallet, or Guitar Pick Holder designs, snap off and file down the "fins" that act as supports on one side of the model.
