3D Printing Projects 202011 – Smart Phone to eyepiece adapters

TPM Technologies Smart Phone to eyepiece adapters. Test fit on binoculars.

Buddy Bob wanted some smart phone adapters for a telescope. Searched on Thingiverse and found many to choose from. Here is a couple of the choices selected.  

 

TPM Technologies Test fit for smart phone.

Some parts were remixed. Thumbnut and Thumbscrew pieces were fit for 4mm Hex head screws. These were applied to the phone locking mechanism. A more traditional thumbscrew knob was used for the eyepiece clamp. The original eyepiece diameter was 1.35 inch and was redesigned for a 1.25 inch diameter using SolidWorks.  The phone clamps on the open ocular unit were modified to be even with the smart phone surface using TinkerCAD.

Parts were printed in ABS on Killer class (FlashForge Creator Pro) and Makerbot Replicator  and in PLA on Ender 3’s.
