improved kant twist clamp

inspired by https://www.thingiverse.com/thing:2833822

is it a remix if you just redesign from scratch?
I do that a lot

also, I use metal hardware instead of printed because there is no way to print strong bolts

use double jam nuts on any parts you want to move, including the jam nut block

Jam nut wrench works poorly,but it is hard to find jam nut wrenches. it worked well enough for me to assemble clamp twice. (maybe someone remix this with a keyhole to keep end flexing)

you need the following M8-1.25 hardware
(2) standard size nuts (knuckle and threaded reciever) https://www.amazon.com/gp/product/B012SZQE5O/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1

(10) half jam nuts https://www.amazon.com/gp/product/B009EFYYWC/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
