Camera lens customizable filter adapter

thingiverse

This is a generic filter adapter written in SCAD usin the threads library. The thread sizes can be easily modified modified in the scad file. Most common dimensions (49,52,55,58,62,67,72,77,82 mm) are generated as STL.3D Printing is a bit tricky, as supports are needed. Supporting bridges might also help. Layer height should be small (0.1mm) due to the very fine thread pitch. I achieved better results with printing upside down (rotated). I have tried to add an extra thin ring, which could lead to a better printability (those are the *_extraring STL files), so I am looking forward to a feedback whether this actually helped or not.The *_extraring STL files are designed to be printed only upside down (need to be rotated in the slicer!).
