This is a remix of user Universal Camera Phone/Microscope Adapter by ggoss.
- Accommodates 5mm hex bolts (5x25mm x3 & 5x50mm x2);
- Includes permanently friction-welded hex bolt retainer caps;
- Channels for applying hot glue which, when cool, acts as rubbery grips (eyepiece & phone grips) and;
- Larger frame to accommodate larger smartphones (including Wiko Pulp Fab).
We've included the SketchUp 2015 file for those wishing to edit it using SketchUp.

The entire model shown is printed at 30% infill but the rails should probably be printed at at least 50% or more.
This requires a few extra steps.
- The tolerances are tight, and some sanding/filing might be needed to get the hex bolts and nuts to fit;
- The nuts need to be friction-welded into the knobs (or super-glued);
- The retaining covers need to be friction-welded (or super-glued) over the hex bolts when in place and;
- Apply hot glue into the channels ensuring it fills them completely. When cooled, the hot glue will act as rubbery grips, held in place by the shape of the channels.
Note on Friction Welding
Friction welding involves using a short length of 3D printing filament (PLA) placed in a small collet of a rotary tool set on its lowest speed. Use safety glasses and be mindful that no one else is around because pieces will inevitably fly. Put slight pressure on the spinning filament at the joint you are trying to weld and keep it there until the friction melds the filament then slowly create a "bead" across the joint.
It takes some practice but once you get the hang of it, it is stronger than glue, usually as good as if it were printed (sometimes stronger).
