Arm v2

thingiverse

These STL files are modified components based on the original Enable RIT prosthetic arm design. The RIT arm is being gradually phased out, and these files are intended for temporary use until new designs are developed and approved. They are meant for users who are already skilled in fitting and using the original RIT arm, although this version has not been endorsed or certified by the Enable organization. This redesigned version features a more streamlined aesthetic with a lower bulk profile and a total weight of just 303 grams when fully assembled. The design incorporates a whippletree adaptive grip mechanism along with a palm incorporating knuckle curvature and thumb relocation to enhance gripping capabilities. The elastics are divided into separate knuckle and finger sections for adjustable finger closure rates. Proper use of these items requires careful implementation of sizing methods, which may necessitate consultation with a medical professional. By downloading these files, users assume all responsibility for correct fit and use. A PDF document in the Thing files section provides print settings and some assembly instructions. Native SolidWorks 2013 files are available here: http://www.thingiverse.com/thing:1156821, while STEP files can be found here: http://www.thingiverse.com/thing:1156799 Printer Settings Printer Brand: MakerGear Printer: M2 Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0.250mm Infill: 35% Notes: All files should be printed in an upright position, with the exception of proxes, fingers, and pins. The only part requiring support is the palm beneath the thumb. Many large parts benefit from printing with a 10-perimeter brim featuring no offset or raft. This decision depends entirely on individual experience with printers and slicing software. A comprehensive document containing my settings and instructions will soon be linked here.
