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
1 M10 threaded bar x 200 mm
7 M10 nuts
2 M10 washers
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
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.
A quick test on my bathroom scales showed clamping force over 35kg
Materials and methods
PLA mostly at 20% infill, arms at 60% infill
