Scanned or 3D printed mirror covers

I have great news on the cover project. I got my printer and have been playing around with printing the Rocinante as a means of getting to know how the printer works. Bit of a learning curve with that. I used a PLA Carbon Fiber filament and the 9 hour job finished this morning. I printed the right side cover and it came out better that I could have hoped. It fits directly onto the fairing, as is, with no mods or changes. The scan was detailed enough to accurately dimension the three mounting studs. Even the studs for the light subassembly screws are there. The mounting studs work for now but will probably need to be replaced with metal studs for permanent use. I'll try to post the .STL and .3MF files but they are pretty big. The carbon fiber finish is kind of cool by itself. I'm not sure how well the naked finish would handle long term sun and weather. I suppose a clear polyurethane topcoat may help. Fairing, sanding and proper automotive painting processes would be needed for color-matching but the base part came out very well.
wow, that looks great!
 
No Joy. Getting "...file too large for server..." error. The .3mf file is 14KB, .STL is 53KB. Maybe a DropBox thing?
 
Very nice work! And posting the files for all is very kind of you. Now to see how they print in more weather-hardy materials. I usually use ABS with good success. Only 9 hours to print? That's fast too! I've been working the model to reduce the supports and strengthen the attachment points bc printed pieces are never as strong as molded ones. But to simply have a part in hand is great. Ooh, wonder if the whole housing could be made into a turn signal...cheesy? Lol

Again, awesome work!
 
Glad to contribute. This is only the right side cover but using the mirror function gets you the left side. I'm fiddling around with the infill settings in Slicer to see about changing just the three mounting studs that interface to the fairing clips to 50%. The rest of the cover is the default 15%. The cover is very light but changing the infill on the studs may make that section stronger. I'm just a newbie with this 3D stuff and I know I'm just scratching the surface on what can be done. Lots of good YouTube How-To videos from Bambu Labs on how to modify the print files.
 
I've had good luck with glass filled PET, very strong and reasonably UV resistant. It'll definitely be after being painted...

Plus it's not too difficult to print with.

Just make that area solid or increase the wall number to add strength. Sparse infill doesn't offer a ton of strength no matter the settings.
 
Here is the finished product mounted. These covers will go straight onto the bike with only one modification. I had to drill out the holes for the light subassembly. They fit right into the mounting stanchions like they are factory. Even though the studs on the covers are not steel bolts, I think they will hold just fine. They didn't get chewed or damaged after taking them off and putting them on several times. These are much lighter than the factory covers. Even though they have hollow interior sections, they seem to be about a stiff and resistant to flexing than OEM.

When I picked up my bike, it was a salvaged title. The previous owner put 16K miles on it and slid it into a ditch, busting up some of the body work. The saddle bags, front fender, mirror cover(s) and front lower cowl/radiator cover were damaged. They even cracked the clutch cover, repaired with silicone which I replaced long ago. The front fender was a master class in bondo and metal reinforcement. I got a good one from e-bay, cleaned it up and put a carbon fiber wrap on it. The color match of the printed mirror covers is very close to the fender and they compliment each other nicely. I added some black and red pinstipes to the bike to help tie in the black body parts to the factory red. I'm very pleased with the results.

It looks great. Very well done!
 
I'd be happy to host these on my Github pages or somewhere else so it is widely accessible. I recently bought an ST1100, with no mirrors, and I'm desperate to get these files!

Hey guys, so I bought the model from the CULTs website. My job has a 3d printer which I can use. I printed it out with some ASA on my coworkers recommendations (the rationale being it will get quite hot outside in the summer). Don't mind the teal color, it was the only next-day shipping available flavor of ASA. I didn't do any additional cleaning of the print in any modeling software. The holes for the turn signal might need drilled out a little.

The print went pretty well. I was not able to bring my bike to work today as I have some plans this weekend out of town and I have too much luggage for the ST. I'll be sure to update when I get the chance, but here's the tentative photos:

Assuming that it fits and I don't need to do a reprint I plan on sanding it down and cleaning it up some more. Then I'll likely coat it with epoxy and possible a fiberglass fabric layer. Then prime & paint of course!
Here's some photos with the supports removed.

If anyone wants the 3D model send me a message and I'll send you a link to the google drive. I'm not super sure if someone can hold the copyright to a 3D scan of a part that Honda designed, or more importantly if I'll get in trouble. Alternatively, show them some love for scanning this unobtainium since it's only $25.
 
All this great work being done, and meanwhile the 3D scanner I bought FOR THIS PURPOSE still sits unused on my desk. I have tried to scan it, it just turned out to be a sucky scan and haven't had the time to REALLY deep-dive practice.

I have also bought a model and was working on modding it for printing. But I'm just glad someone's picking up the ball to move it forward.
 
A valid concern. Staying low-profile will help. Maybe flash the site with a MIB neuralyzer.

F'rinstance advertising on FB or eB might not be a good idea.
I'm considering making my own model that looks very similar (but not a scan) in solid works. I work with a bunch of engineers so I keep telling myself that I'll take the opportunity to learn solid works lol. In that case I could post it freely.

I also went ahead and bought myself some replacement turn signals as my bike is missing one and the others broken. My local parts store's website had them for a $59 ea/ but they're getting hard to find too. Could consider trying to make it fit another bikes then signals that look similar but are more available.

I stopped home after work before to try the fit and it was PERFECT. I left early so my coworker was nice enough to start the print so I should have a right mirror I get back on Monday.

I think the new plan is sandable primer instead of epoxy.

I'd love to help print these for others but I think there is enough demand that I couldn't help without hogging the 3d printer we use for actual work, but too little to justify the $1200 of buying a nice one myself.

Edit:
So unsurprisingly the turn signals are not in stock and my order was cancelled. So I may need to find some from a bike that is still in production and modify the STL or something to make it work, or pay way too much to find them online.

Okay so to be honest I didn't love the sandable filler spray paint. It kind of worked, but it felt like it would sand out of the pits. The first mirror I ended up painting, disliking, sanding and repainting and it seems like normal spray paint does a better job of filling the gaps, but it doesn't dry in 2 hours like the sandable filler.

The second mirror when it was mirrored (flipped) had a lot of pitting that wasn't on the first mirror. Going forward I would suggest a putty material like bondo. If you want the best look you would then need to work through different grits until its smooth. Wet sanding may help too, but I didn't want to wait for the plastic to dry before painting. Paint matching is a lot easier if your bike is black 😂

Overall they didn't turn out perfect but that's because I only have so much patience for painting and sanding and painting and sanding. But all things considered they turned out great! They look stock from a distance, and unless I point it out I doubt anyone will even notice.

I went ahead and attached some images from the process as well as the final result.

I was able to get a replacement turn signal on eBay but they are increasingly hard to find. If anyone can find a cheap placement turn signal that looks close enough we could modify the 3D model to fit the cheaper part.

Obviously you will need to drill and tap the screw holes in the print, I haven't done that yet but just using the screw on the turn signal assembly itself seems to be okay for now.

Hi all,

Love seeing these projects! I am planning to 3D print an engine guard cover for my 2009 St1300 that has a set of leg rest pads added to it. It works sort of like highway blades, but you put your calves on them instead.


Has anyone ever modeled one of the factory engine guard covers in CAD who is willing to share the files? I okay at CAD, but it would be a lot easier for me if I had the basic design to start with.

I did a mock up with scrap metal, foam and tape, and its SUPER comfortable (much more than foot pegs).

The printed version will just look like the factory cover but with a "wing" extension.
