Kodak Aero Ektar 77mm Filter Holder Substrate

thingiverse

This is a substrate you can use to create a filter holder for a Kodak Aero Ektar 7in F2.8 lens. You will need to separately purchase an 82mm-to-77mm stepdown ring and apply it onto the substrate with a strong adhesive. You can check out this video for instructions: https://www.youtube.com/watch?v=keRIPLAEUYI&feature=youtu.be I designed this years ago and have had it on Shapeways as a commercial product, but I've more than recuperated for the time, effort, and money that went into the design so I'm now releasing it as CC. Feel free to modify it for your own use & distribution; just attribute the design to me, and do not use it for commercial sales. The short hood of the AE tends to come in slightly different designs so the area of the stopper might be where you would especially want to modify to suit your needs. Also, the circular holes are a design choice I made to minimize material cost, especially since Shapeways is quite expensive. With home 3D printers so good and filaments so cheap these days, you also may want to fill in the holes; they just introduce an additional level of pain in the printing process :P With that said, this design is printing well using PLA with my newly acquired QIDI X-Plus.
