3D print the same bench dog pin and bench dog housing I used in my youtube video.
 
Included in the digital 3D print files are:
 
24mm Bench dog hole housing
24mm Bench dog
 
Included are the .STL files that you can import into your preferred slicer program to print your own!
 
This file is suited specifically for the following Hafele push door catch mechanism available from Bunnings.
 
The lip of the housing sits 3mm below the surface of the bench.

Suitable to be printed using most standard filaments, including PLA/PETG.  I do suggest that if strength is your concern, increase the internal fill % as necessary.
