All I've done is split the model with a dovetail cut to fit the A1 mini plate. The Sy's peglock are custom resized to fit my Australian metric pegboard the peg diameter is 5.6mm.

To generate custom peg sizes use this onshape model and adjust the configuration panel as needed.

Printed with PLA printer settings are as saved in the profile.
