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);
}
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.
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.
No, it like the lens cover on compact cameras that opens when the lens comes out as the camera is turned on.
On my camcorder it jumps open when you turn on the camera either by opening the screen, pulling out the viewfinder or pressing the “on” button but I think on RS’s it is a manual affair separate from the camera - sort of a lens hood arrangement.
