A jig to create joints between wooden panel and especially chipboard

This version is designed for 18mm thick panels and for the hardware I have; that was the reason of my remix, the RuL3R original one is very good but not for hardware I found on local market).
This type of joint involves a pawl that is screwed into an 8mm hole and to which the gudgeon pin is in turn screwed. The connector housing, on the other hand, is 12mm in diameter so I provided a 15mm hole since it is a common size of forstner or dovetail drill bit.
The smaller hole is for making a mark with a maximum 4mm diameter bit and then enlarging with the 8mm bit using the depth stops of the side holes.

I printed it in PETG but it should be fine for more or less any material

Usage / Instructions

1. Take the piece where the edge and face work needs to be done (wood piece A) and make the hole for the gudgeon pin and the one for the pin with the 8mm bit
2. On piece A, use the 15mm bit to make the hole for the connector housing 
3. On the piece with the face only being machined (wood piece B), taking the right positioning, make the two lateral holes with a diameter of 8mm
4. On piece B for the central hole you must first make the mark with a maximum 4mm bit and then make the hole with an 8mm bit, perhaps moving the template and using one of the lateral holes so as to optimize the use of stops of depth
