To make: print one knuckle and 3 claws. Place glue on the sliding portion of the claws and slide each into the area on the knuckle. If your 3d printer's printing surface is not very large you can print one of "1st claw" and one of "2nd Claw" to make a single claw (fitting the claw halves together may require sanding as well as fitting the claws to the knuckle), if you want it to resemble X-23's claws I've made a thing to slide into the center slot. Once your done you can finally kill some bad guys! (Works for both hands however the finger holes are sized for my hand so it may not fit you). This is my first formal creation thank you for those who are interested! If you have made one please show me I'd love to see it :)
