3D Printed bobbin or the Chinese Leather Shoe Patcher Sewing Machine or CLSP as its called.

 

This bobbin design uses a 3 notch top simplify the design with a 0.10mm boolean added as tolerance as a 100% accurate design will not print.

 

1st two are initial print on machine warm up and the setup may not have been the best so rough. they were the 100% accurate design and did not fit.

 

The Right side one in the back is the new V3 Notch next to the V1 split design. V3 is 0.9mm lower and I don't know why on the other hand the sides have some stiffness to them Vs the 0.2mm the V1 printed out at. The 0.10mm removed at the meeting edges was enough that they fit nicely at 0.20mm layer height. I just have to fix the capacity problem for thread and preferable figure out why they are printing short.

 

The bobbin works now I have gone at the needles and timing and testing with the 0.1mm type monofilament plastic line it came with. The tension must be off as the lower thread is pulling up through the holes. More polishing of the machine is probably required.
