A simple adapter for aligning the lens of a Nikon Coolpix P330 with a Leitz Wetzlar Periplan NF 10x eyepiece for taking pictures through a microscope (photomicrography). You slip the adapter onto the lens turret of the P330, and then press it flat against the eyepiece.
I include the .f3d file so that you can open it in Fusion 360 and make changes if necessary.This adapter can likely be adjusted to fit any eyepiece/camera setup as long as the camera has an extendable lens turret.
Some support is needed for the eyepiece side of the adapter. I recommend enabling a layer of "dense support" at the top of the support stack to help the bottom face come out flat and neat.
