This adapter, like my other designs, is printed in two pieces that get glued together to eliminate a lot of ugly support material from the print.  The tube fits tightly on the Meade 32 mm Super Plossl eyepiece.  It can easily be modified to fit other eyepieces for either microscopes, binoculars, or telescopes.The base piece fits tightly on the phone.I sliced in Cura with 25% infill, no brim, no  raft, 0.25mm layers, support material "everywhere".In this video, the rabbit pup was about 50m away: https://vimeo.com/130577129Images produced have pincushion distortion, easily corrected in Gimp.  The second photo was shot through the telescope- the stop sign is about 1/2 mile away.  The original image had some pincushion distortion so I corrected it and mirrored the image in Gimp.
