This is a fixed version of the Dog Hole drilling jig which sacrifices flexibility to eliminate any movement between the jig and the dogs used to position it. Not printed or tested: I created this remix at the request of a printables user who was having trouble with the original model.
This version still requires a 20mm dog hole drill bushing, such as: Dog Hole Bushings - Lee Valley Tools
EDIT: There are now four models: a corner jig (for the first hole), an edge jig (for subsequent holes in the first row) and a “full” jig, with three full pegs for drilling additional holes once the first row is complete. The fourth model is a more flexible version that can be used at a corner or on and edge. I've included STEP files.
Easy changes can also be made with Onshape - here's the original document: https://cad.onshape.com/documents/1e4708b0adfe5a8bbcc5399f/w/bf2e15f9a7bdafdead8f305c/e/39adee13ccfd5e39bcf402b5?renderMode=0&uiState=674614ef54da1336707c0446
