Suppose even the best design's need to go through the whole process before there done.
And at least go did something about it, I'm good with spanner but completely usless with computers, the whole design would live in my head forever! You've thought it through and actually made it !

nice one.
Ha very true!
Another short update, after actually fitting the fascia I had printed, and putting my pioneer head unit into place - I realised I had a fundamental flaw in the design. This is mainly due to fact that the Double Din unit can NOT match the angle of the trim area. As you may have read in a previous post, I had added a curve to the fascia but due to printer limitations in terms of quality of the print, I then removed the curve and kept the "flat" face.
After trying a fit with the cage in place AND the head unit itself, I realised the cage walls needed to be at an angle
Also, due to printer constraints and the way in which FDM printing occurs, there was very little strength where the edges of the cage met the front of the fascia. After trying numerous print orientations and settings to increase the strength and some discussion in a 3D Printing group, I decided to print the walls separately and use JB Plastic Weld Epoxy to affix the wall/edges to the fascia front.
There was also the fact of working out a venting system ... this is still very much a work in progress, but the current stage looks like this:
This too will be in sections that would need to be epoxy'd together... and I would also use some silicone at the join lines to help make it air tight.
As always, this is still a WIP - but I believe my fascia is almost complete
In my case, there was 2 options, have the bottom flush at the front, and the top protruding - and then fashion some kind of top cover, OR as in the pic, have the top flush, and the bottom is set back and I will at some point fashion something to cover the gaps left (please note, that in the pic you can see it is merely propped up in place, it would infact sit a little further back and "beyond" the fascia a fraction). The stereo is too large to match the angle of the fascia... I am currently printing off my venting design thus far.. I will update again once it's finished printing and I can get an idea of the next step.
