This dial extender allows you to easily change the shutter speed dial while it's trapped under the metering prism connection. I consider it a necessary component as it's very awkward if you don't have the Pentax ring (and it seems that is a missing component from many setups).

Print Settings

Printer:

M3D

Rafts:

Yes

Supports:

No

Resolution:

High

Infill:

Full


Notes:

Tumble Print 180% from how it appears in the file to avoid overhangs, I had to scale up to 102% to get a perfect fit but I imagine that depends on your printer. This file does make concessions (via a recessed channel on the underside) to avoid colliding with the battery check light.

Post-Printing =============

I did not have to do any finish work to get the print to mate reliably with the dial on my Pentax 67.

How I Designed This

Took measurements with digital calipers, Made outline in Adobe Illustrator (exported as SVG) and extruded and finished design with Autodesk's 123D Design on the computer (too complex for the mobile version).
