This is a Ricoh WG-M1 Action Camera 72mm Filter Adapter made with Tinkercad and can edited on online at https://www.tinkercad.com/things/13HOMtO6AWE The idea of this is provide a way to attach 72mm filters in front of the Ricoh WG-M1 Action Camera. The reason for such a large filter diameter is to reduce the possibility of vignetting in frame.
Keep in mind the closer the camera lens is to the filter the, less vignetting which will occur so would suggesting sanding as needed the inside ring to archive the desired results.

While 0.2 is workable, the inter-threads improve by printing at 0.1 so you experimenting we would suggest 0.2 however for the finial working version we then kick it up to 0.1 for improved resolution of the inter filter threads.
