Yeah, I'm going to get carried away with things that don't necessarily need to be changed/updated but hopefully it will be my path to better projects. Now I don't even recall what the original horns looked like but long ago I replaced them with Hella units and using the OE brackets the inner horn basically rubbed up against that horizontal support. I kept the length on these the same but rotated the horn end 45deg resolving the rubbing. You can see how much better the left side bracket printed upright turned out vs the other printed horizontally. I thought I might not have sufficient cross section (vertically) for good adhesion on the print surface, but turned out not to be an issue. Right side one is also too long and thinner. I also see how the two free tabs on the horizontal support would really get them out of the way and pointed forward. May have a look at that too.
Cool. Will those be strong enough to hold the horns during the road vibrations and pothole hits, etc or are they brittle? I don't know anything about 3D printing, but should get my son into it so he can make me stuff.

I believe they are strong enough. Straight PLA is brittle. This
Has good toughness and flexibility. If you twang the horn it will vibrate but it is it damps out quickly. Probably could make it a bit thicker too.

What material are you printing in? In my experience, nylon filament has great material properties and is chemical resistant. Can be difficult to print with though. Just gotta dry it out first and print real slow. I go about 10mm/s with it. Takes forever but that parts are strong as any injection molded equivalent.
@AngelP : Can I ask what your printer is that is delivering those parts? That's some really nice, smooth parts that you're getting. I'm not really up on the state of the art so maybe all the new printers are giving this level of results but these parts, and the others you've shown recently, look amazing.

Definitely Nylon is at next level compared to tough PLA but as I'm just getting started on this haven't invested in the higher end filament. Is 10mm/sec really the recommended speed?
That is really really slow .

Thanks, its the Anycubic Vyper. I spend ages deciding on a printer but these days any decent entry level printer is probably comparable in print quality providing the filament isn't crap.
