Car relay mounting adapter and car relay dummy for high-power mini 12V / 24V car/truck relays.
Relay dummy has plug matrix B2 (see manufacturer datasheet for details).
Why
The cheapest relay I was able to get didn't have a mounting flap. Also needed a dummy for fit tests. Didn't use it in a car, though.
Design Details
Made for 35x35mm car / truck relays that come without a mounting adapter. I think, these are ISO 7588-1 compatible.
Mini relay with ISO 8092-1 blade connectors but please don't connect voltage to it.
Due to low melting temperature of PLA probably not good to be used in an actual car.
Several versions are available:
With holes:
Mounting flap 0 deg
Mounting flap 90 deg
Without mounting flap
Without holes:
Mounting flap 0 deg
Mounting flap 90 deg
Without mounting flap
Mounting adapter STL available in
M3 bore hole (2.6mm)
M4 bore hole (3.4mm)
M5 bore hole (4.3mm)
M6 bore hole (5.2mm)
3.5mm hole
4.5mm hole
5.5mm hole
6.8mm hole
At a later date, I might try to offer a parameterizeable version.

Print Instructions
Print in displayed print orientation for better strength.
Adjust infill density to personal preference. 100% infill for mounting adapter recommended.
Different color than black might be good to make sure that the dummy relay is removed before operation of whereever this is used.
Please consider using a different material for printing if PLA isn't suitable for automotive use. Fire hazard from wrong material possible.
Assembly Instructions
Print and snap relay into place.
Materials Needed
nothing (screws according to car manual if installation in car is needed).
Tap needed if thread required.
