Holga Sunny Aperture Replacement Arm and Custom Bokeh

cults3d

What good is the "sunny" switch on a Holga? It's about to get a whole lot better! Inspired by scherbi's "Holga Repair and Aperture Modificaiton" instructable this is a replacement aperture arm for the sunny/cloudy switch on the Holga. Follow the instructable to step 6, at which point replace the original arm with your newly printed part. To make the part, print the corresponding base and crown files for whichever version you choose, and glue them back to back. There are three versions included. 1_The blank version is for you to drill the hole yourself, which is probably the cleanest and most accurate approach. 2_The Sunny version is a simple round hole, which is just under 1/8" which leaves you a little room to deburr the edge for a 1/8" hole. The idea was to create a Sunny 16 option, but I'm not sure if it accurately rates as f16. 3_The Heart Shaped Bokeh is sort of an untested experiment. Have fun! I've included the orginal FreeCAD file so you can remix and add your own new bokeh shapes!
