Graflex Speed Graphic Barrel Lens Board
thingiverse
Download and open the .scad in OpenSCAD to customize. You'll need the BOSL2 library and I don't think Thingiverse customizer supports that. BSOL2 makes rounding the corners much easier and sizes more predictable. I was having issues with the sizes coming out wonky after rounding the corners on my own. OpenSCAD is weird like that and I'm no expert in it. More info on the BOSL2 library here: https://github.com/revarbat/BOSL2 User editable parameters * lensDiameter Outside diameter of lens barrel to be held by the board 3 Inch max. Larger than that and it will be larger than the board. * lensFrontSupport Length of the tube protruding out of the front of the lensboard. * lensRearSupport Length of the tube protruding out of the rear of the lensboard. * renderSmoothness Controls how smooth the curves are. 100 is usually sufficient for the STL render for a 3d printer but feel free to crank it.
