2 way threaded bolt

1 bolt with 2 threads that work in opposite directions.
This way the nut with the right- and left hand thread wil screw on.

This design may look a little more traditional than the usual ones u may find on this platform. This is due to the low "pitch" of the thread.
The bolt is designed with a tolerance off 1mm (1/2mm allround). With this big of a tolerance It's possible to succesful print the file on a less accurate printer. This also gives you the option to scale down the model.

In a couple of days i will up date the post with better pictures and maybe a video.

Dimensions of the Bolt
Diameter: 36mm
Threadlength: 120mm
Total length: 140mm

I have printed this file with the least amount of filament. The settings were:
Infill: 15%
layer height: 0.2mm
Perimmiters (walls): 2
Top and bottom solid layers: 3
