Description

The Ford Sierra has non standard rear speaker mounting holes, so I made a little bracket to be able to properly mount an aftermarket speaker, in this case, an Alpine SPG-10C2. I have attached the Solidworks file as well should anyone need to change measurements! Printing: The model is pretty straight forward to print, there is a face that is entirely flat. Works with any infill over 20%. In my case, I used cubic 20% in Cura. It took about 2h on my not so fast printer for each part. Note: It is best to print a normal version and a mirrored one, although it works either way! Hope this is useful!
