Flying Clamp for Tennis Stringing

This is a flying clamp for tennis stringing.
It was actually tested with my stringing machine.

You have to print 2 center_parts, 2 side_parts, 1 lever_parts for one flying clamp.
Use 60% or more for fill when printing for the strength of the parts.

You need additional parts following,

1) a M6 eye-bolt (L=60mm) *You can buy it from Ali-express*
2) 4 D5 x L3mm neodymium magnets *You can also buy it from Ali-express*
3) 2 M5 bolts (L=30mm and 35 mm)
4) 2 M5 nuts and a M6 nut (lock nuts recommended)
5) Some sand paper (#200 -600)
6) 4 small tapping screws (L=10 to 12)

a pair of neodymium magnets is used for the substitution of a spring.
Place magnets into the D5-holes so that they repel.

Cut out 4 pieces of sand paper using the guide printed and paste them to the parts for string slippage prevention.

You may need some leutor works depends on the accuracy of your 3D printing.
