Larger Gripper for blocks

thingiverse

This is modified gripper better suited to pick up blocks for FTC Freight Frenzy. Early reference grippers have fingers that curl into ball which did not work as well as this version for blocks. This is sized to fit Creality Ender 3 Pro Bed to corners, Use Ninjaflex for gripper. I used PLA+ for other parts.. This is designed to be used with a motor mount and spool to spin wire cables. Note adjustment screws on spool allow adjusting tension on each finger separately, similar to adjust guitar strings. Designed for FTC legal servo. Stainless steel cable is used and standard cable crimp sleeves. I used AHANDMAKER 304 Stainless Steel Wire Cable with aluminum crimp sleeve from Amazon. Crimps are used at each end of cable for each finger. Screws are adjust and match tension on all four fingers of gripper which was difficult to do with original reference design. Crimps hold tension better than screws of original reference design. Note spool has Gobilda servo horn designed in, so this needs a Gobilda servo or one with similar 25 tooth spline.
