Tools – 3D Printer

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){

And you get this:

OpenSCAD – The Programmers Solid 3D CAD Modeller

FreeCAD: Your own 3D parametric modeler

Leica film cutter

Minox fim holder scanner

Minox film cutter (35mm to 9mm

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.
