I designed a nikon to orion telescope adaptor in the sprit of the perseid meteor shower.
The latest version is working great. It press-fits over the eyepiece and now has an extended shaft for better focusing. This design is rugged, stable, & the adapter locks into place with a satisfying click.
Also attached is a Rhino version of the file of you want access to a nurbs based version of the CAD.
Fixes in the latest revision:
-Widened barrel to press fit over the telescope eyepiece
-Extended barrel for proper focusing
-Cutout on the edge to help align the adapter to the body
-Chamfer replaces the support material
.15 layer height recommended
