Tời quay tay cho dây 6mm

i needed a simple hand cranked winch for pulling on some ropes for moving the shading net over the veggies garden. No reduction gears needed as it can easily lift a 20kg weight.

It has a simple latch using gravity, 3 mounting holes to what ever support ( wall for me)

I used what ever screws I had on hand, 

2ea M5x20 hex screw cap for the handle and the latch

3ea M5 threaded rod 90mm

3ea M3 threaded rod 55mm

1ea M5x60 for the lever, or use a piece of M5 threaded rod

9cm piece of 24mmOD broomstick wood for the main axle

some M5 washers for a smooth movement of the handle and latch.

Prints without supports but needs assembly.

The rope goes through the middle section  6mm hole and locks in place when tension is applied.

This is my 1st try at something this complex………but it seems to work.

I guess i could make one for an other OD wood rod if needed

Printed in ABS CF11, 3-4 walls, 3 top + bottom, 20% adaptive cubic.

0.2 for most parts; 0.15 for the 3 small M3 threaded parts

In the split parts STL they are all correctly oriented

As for tolerances, there is a 0.05mm or 0.1mm gap for the parts needing assembly.

The holes might need some reaming with a 5 mm bit if the tolerances are too tight 

EDIT 1 : the piece of broomstick used as a shaft needs to be drilled once the larger drum part (with the teeth) has been properly positioned.

The axle needs to be recessed by 3mm from the bottom of the mounting plate. I added a picture for reference

EDIT 2: the 3 small triangular parts are threaded M3, it makes it less painful to push the threaded rod in to lock the assembly. Friction and tension are enough to hold everything in place.
