I lost it during cleaning the paint gun.

Bought a second paint gun to finish the job and recognized why the first one didn't take color anymore, the washer was missing!

No way to buy a replacement! So i made this tiny openscad file to print my own.

https://www.printables.com/model/934438-paint-gun-venturi-washer

dia_outside = 33.2;

dia_inside = 21.2;

wallsize = 1.2;

dia_holes = 3.0;

thickness = 1.1;

holes = 20;

height = 2.8;

$fn=120;

union(){

`difference(){` `cylinder(d = dia_inside + wallsize*2, h = height);` `cylinder(d = dia_inside, h = height );` `}` `difference(){` `cylinder(d = dia_outside, h = thickness);` `cylinder(d = dia_inside, h = thickness);` `d = dia_inside/2 + (dia_outside/2 - dia_inside/2 + wallsize)/2;` `for(a = [0: 360/holes : 360-360/holes])` `rotate(a)` `translate([d,0,0])` `cylinder(d = dia_holes, h = thickness);` `}` 

}

I designed and printed this support leg bracket, which then doubles as a carrier for the leg, for my little trailer. This saves having a bulky jockey wheel and has repurposed a metal wardrobe hanger bar that I had knocking about. When stowed the clip at the rear holds if securely in place, to prevent road vibration wriggling it free, and when in use the metal bar/leg sits butted against the metal trailer draw bar, so theres no plastic to fail. Tolerences are really tight to ensure a snug fit.

Printed in PETG at the moment, but I will see how it lasts and if it's worth reprinting the foot in TPU and the body in a CF mix.

Overall really pleased with the design and functionality of the piece, but open to input or suggestions if anyone has any.

Needed a solution so I designed this. Warped a bit, but still works perfectly. Love it when concept to design to print is not an iterative process.
