Digging claws: Heavy duty hybrid

thingiverse

I created a more rugged design, with survival shelter building in mind. You could also be the change you seek in the world, by building an underground Ho Chi Minh trail, as a combat engineer? Who knows brohs? These digging claws are designed to accept "tooth" inserts, like on a hydraulic excavator shovel. The included "tooth" object can be printed with extreme durability filaments (or even cast from metal, when used as a mold negative). The claws should be printed from cheap PLA or ABS, and the inserts are then attached with a high strength epoxy glue. If you need maximum claw strength (for some maximum effort undertaking), the object can be rotated 45 degrees, onto the flat chiseled back. You will need to enable supports, but by printing the part laying down, you get better strength. Default object size: 22mm diameter at opening 20mm diameter at 15mm deep 14mm diameter near the finger tip I used calipers to loosely measure the width of my fingers with biking gloves on. Then I created "hole" objects in TinkerCAD, sized to the width of my fingers, and I scaled the claws up (and down) for each of my fingers.. by scaling until the opening loosely matched the width of the "hole" object. The "tooth" will also need to be scaled the exact same amount. Printing five at once, takes 10-12 hours (at 0.3mm), even at a slow 40mm/s print speed. To scale a set and print quickly, In Cura, duplicate the claw or teeth (ctrl+M) four times, and then scale dupes in 10% steps. For example: Sm: Thumb: 110%, Index: 100%, Middle: 90%, Ring: 80%, Pinkie: 70%. Med: Thumb: 120%, Index: 110%, Middle: 100%, Ring: 90%, Pinkie: 80%. Lg: Thumb: 130%, Index: 120%, Middle: 110%, Ring: 100%, Pinkie: 90%. These will also work if you want to be "Edward Chiselhands" for Halloween?
