3D printing is a tool I use quiete often, eg. lensboards, lenscaps, spare parts,…

First I used Googles sketchup, but since it got online only, it lost me due to restrictions

Mysoftware as now is freecad, fusion 360 (free) , openscad (t seems difficult at first but is fun to use, especially as you can throw .stl files in the editor window and at once get a solid form to work on)

So usually I throw the .stl file in openscad, define the path as a module and can work on it.

Like so:

module linhoflb(scale){
    import("D:/Dropbox/linhof_board_blank.stl");
}
difference(){
        linhoflb(1);
        translate([265,175,0])
        cylinder(h=6,d1=50,d2=50);
}

And you get this:

I decided to print a few lensboards for my Graflex Speed Anniversary to use them with some old lenses.

And – being on my way, I printed a few waterhouse stops too.

( waterhouse stops  : hole size = focal lenght / aperture )

(to get the focal lenghtof the oldtimers : projekt a light source on a paper and measure the lens distance to the paper when picture is sharp – the further away the light source the better (sun ?

Formula : 1/f = 1/g + 1/b   focal lenght = 1/distance object + 1/distance projection ) .

I know, its just a approximate value but its enought…)


Everything working great.
