Adaptor to connect an OBD2 port to an ATI CANary
The zip file contains all the files required to make the PCB, just drop it on to a PCB manufacturing web site, choose the colour and pay the fee. Examples:

Both charge about $5 for 10 boards, and about twice that for shipping.
You will also need a case, there are 3D printing files in the CASE folder. The case is held together by 4 off M3 x 5mm x 8mm heat-set inserts and 4 off M3 x 16 countersunk screws
Additional components:

HD15 socket: Amphenol 10090926-P154VLF https://uk.rs-online.com/web/p/d-sub-connectors/7361510
SIP switch x 24: APEM SIP-08TV https://uk.rs-online.com/web/p/dip-sip-switches/8772384
You can probably get away with only 16 SIP switches to connect only the data lines.
Note that since making the one in the pictures I have rotated the right column of switches so that they all operate in the same direction and also rationalised the row order.
It is designed to connect directly to a CANary, but with an HD15 gender-changing coupling it can be used with the CANary HD15 to 4 x Dsub cables too.
Bail screws are an unsolved problem. Maybe the case could be modified to incorporate a clip to hold the HD15 together.
