Gripper Design Iterations[edit]
Updated Version 1[edit]
Made ribs thinner at their ends so that they would bend more easily. Added triangular cuts along the inner surface to allow the material to flex. Problems: The triangular cut closest to the tip caused the inner surface of the grippers to tear.
Updated Version 2[edit]
Moved slots to only align with the three thickest ribs, reducing potential for tears. Created an angled profile where the tips of the grippers are narrower than the base. Problems: Screw holes were too large for screws to be inserted from below, tears persisted in some cases.
Updated Version 3[edit]
Decreased hole size to allow for better threading. Problems: Tears persisted, insufficient clearance for hex key to actually tighten the screws from above (necessary for use with slide rail).
Updated Version 4[edit]
Decreased profile of rib material to make screw installation process easier, decreased cross section of individual ribs to allow them to bend more. Problems: Too flimsy in general, and particularly at tips.
Updated Version 5[edit]
Restored rib material and eliminated one triangular cut to solve tearing issue, attempted to print entirely without supports. Problems: Poor print quality due to lack of supports.
Updated Version 6[edit]
Used solid tip and fewer ribs in the other section. Assembly with screws remained awkward.
Updated Version 7[edit]
Switched cuts to the inside wall and eliminated redundant rib.
Updated Version 8[edit]
Tapered inside wall and extended it to the now restored rib.
