3 Jaw Lathe Chuck
Have us print this for you
PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
****UPDATE****
Durwin Pye has sorted out the Scad file so it is now brilliant, Thanks,
I have added it to the list of files -not for the faint of heart-
After printing some other designs and finding they did not work for me, I decided to have a go myself, So here it is, Please beware, I have made allowances for my own printer so I take no resonsibility if it doesnt work for you.
Also, to state the obvious, this is a plastic chuck, it has its limits!.
101mm diameter, 59mm thick plus 25mm jaw height.

for the hard work
****UPDATE****
I have printed and tested (sort of) different jaw materials And added photos
ABS,......................Best grip
Flexi at 85% infill ..2nd -being flexible they grab well
PLA ......................3rd, ok but tend to over tighten, which could break the scroll
NYLON..................3rd equal

I have not included the Scad file at the moment, as it is a real mess,

Thanks to Durwin Pye for cleaning the scad.
