Replacement peg for the cheap Wilkinson's branded plug-in timers. I think it's a generic product re-branded.

Link to the timer (for reference purposes, I do not endorse)... http://www.wilko.com/extension-leads/wilko-mechanical-segment-timer/invt/0343076

The one I printed has been tested and works well.

I deeply suggest that you use the suggested print settings.

Apologies for the state of the SCAD file, I may update it at some point to look a little less of a disaster!
