I recently bought a new camera bag for my camera, camcorder and accessories. Nothing wrong with it. I paid $23.95 (£12) for it on special on Amazon.
I put the camcorder in the bag lens down and worried that if an object from another compartment got underneath the lens it might damage the opening mechanism. So decided to make a lens cap on my 3D Printer that fits over the lens hood.
The code was very simple::
//Lens cap for camcorder
// Variables
capexd=71.7; //external diameter of lens
thk=2; //thickness
hyt=5; //cap height
//End variables
$fn=100;
difference(){
translate([0,0,0]) cylinder(h=hyt+thk,d=capexd+(thk*2));
translate([0,0,thk]) cylinder(h=hyt+thk,d=capexd);
}
The result looked OK:
It took me a few test prints to get the size exactly right. I wanted it to slip on easily but not fall off. A 0.2mm adjustment made all the difference.
They only took a few minutes each to print.
The final result was quite pleasing.
Well, I was pleased anyway. It fits nicely and protects the lens mechanism. I could spray paint it black I suppose but being yellow means I can find it! and it is only used while the camcorder is in the camera bag.
