Kant twist clamp

Vitamins

If using threaded pins

5 M5 x 16 1 M5 x 12 ( or 6 M5 x 12) 3 M5 x 45 1 M5 x 35 4 M5 nylock

If using through pins

5 M5 x 45 2 M5 x 35 7 M5 nylock

Also

1 M10 threaded bar x 200 mm 7 M10 nuts 2 M10 washers

Instructions

Print the parts in the orientation shown. Most parts at standard settings, the arms I print at 60% infill.

• Clean up and ensure the pivots rotate cleanly in the sockets • Make sure any threaded parts work well • Fix one end of the M10 threaded bar to the short pivot using 4 M10 nuts and the two washers making sure it can spin freely • Put a M10 nut into the long pivot (if not using the threaded option) and wind the long pivot along about half way • Attach the handle spinner to the handle making sure the spinner can spin freely • Attach the handle to the other end of the threaded bar using two M10 nuts • Now assemble the short arm (apart from the through pin) using the short jaw, M5 x 35, nylock and M5 x 16, M5 x 12 if using the threaded pin. Making sure the short pivot can rotate freely. • Lastly assembly the long arm around the short arm using the long jaw, M5 x 45, mylock, and M5 x 20 • Enjoy

Notes

I did do a version using M8 threaded bar but the movement was too slow. Printed in PLA which means the jaws are slippy, I may try gluing a bit of rubber to one side to help grip things.

Also, banana for scale, but it's a big banana. Also I would make the stls in the right orientation if I knew how in Fusion 360.

Yes, I don't have M5 x 35 in stock, and I don't want to cut down an M5 x 45, they're on order.

Quick test on my bathroom scales showed clamping force over 35kg
