Please see the updates and notes detailed at the bottom. Print in place long reach grabber, Uses compliant mechanisms and functions right off the build plate. Print WITHOUT supports. Designed with clearances of 0.35mm, if your printer can print moving parts with a clearance of 0.30 you should have no issues. Be mindful of your first layer, if it's too squished it'll fuse the shaft to it's keyway. Once printed, I recommend pushing the plunger forwards, not backwards, to break in the movement some before pulling backwards. I've been using PLA and been fairly durable using cheap eSun brand filament. Tho I suspect that different blends of PLA from different manufacturers will have differing flexibility. Your mileage may vary. I was inspired by this design: https://www.thingiverse.com/thing:4633366 Made some changes for my design as I wanted it to feel more robust. Thicker shaft with a keyway design so that the whole shaft is better contained within the tool. Bigger thumb and finger holes. Updated: added another gripper type, revgripper_a, meant for grabbing small screws. Update 8/1: Added 2mm to the top so that when printing with layer heights >0.20mm it'll have more than one layer adding to it's strength. Thanks to: suf101 Update 8/14: Added revgrippers_b.stl This is what I would suggest trying to print first. Redesigned a good bit of it. Tolerances have been increased to 0.40mm. Thickened the 'spring' bit that the jaws mate too. Adjust the 'stop' so that it can't be hyperextended. Increased the angle that controls the jaws. Added a slight chamfer to the edges to help diminish the effects of elephant's foot a tiny bit. But your first layer is crucial to printing this successfully.
