Bond it or Screw it to Dashboard?

k1n3k · Friday at 3:47 PM

So I'm working on some stuff I want to 3d print. I am trying to decide if its worth trying to bond it to the dashboard with some sort of adhesive that can later be removed for a damage free installation, OR if I should say screw it and well, screw it.

What material is the dash made from and does anyone have any experience trying top glue stuff to it? I'm at a point where this is going to determine some key aspects of the design. Bonding is preferred id the adhesive can be later removed. Ideally this can be fully reversed without damage to the dashboard.

In the end, I anticipate designing a switch pod, gauge pod, and pair of speaker pods that will go on the corner(s) of the dash.

Any chance you could share the file? I don't own a printer but this spot would be great for a phone mount.

Which one? There are two in that screenshot. The actual part that I test printed and the 3d scan of the dashboard. A ram ball mount design is a good idea, I'll add that to the list.

You could stick it forever and then add some inserts onto it for an easy access to whatever you want to install and take off as many times as you want. Just make that the base.

I'd do whatever option is easiest to replace. Every single thing I've had 3d printed has broken at some point.

uhhh the second photo? they both looked the same to me

perhaps make the top surface smooth enough for a suction mount if that's at all possible for a 3d printer.

I stuck a small instrument to the same spot in my Jeep using double-sided 3M / Scotch Extreme Mounting Tape. If you have a lot of flat surface under your 3D printed platform for the tape, it will probably do the trick (solid bottom, not grid or honeycomb).

Watch out for "3M" or "Scotch" tape on Amazon, almost everything I found was Chinese junk with real 3M logos plastered all over it. I bought mine at Home Depot for more money, just to get the real thing.

Nano tape works. I've used it to stick all sorts of things, it stays put for as long as you need it to, then when you want you can remove it with no damage to the surface and no residue although it takes a lot to remove so the 3D printed items may break apart when pulling them off. It's also a bit on the thick side at maybe 3/32"

The suction cup mount is just not doable as the prints are porous and rough, but a ram ball is. I like this idea enough I ordered the parts to prototype it. I'll share the files when they're done.

Not a bad idea. I've got some M3 and M4 heat set inserts, I'll play with that. I Was thinking about a dovetail, but a universal mount that can just be printed and stuff bolted to is a pretty solid way to go.

rog.

Could try adding a flex seal type tape (super sticky) to the surface and then put the suction mount down on top.

This is what I was thinking.

That way the mount is held to the 3d printed bracket with some M3 or M4 screws with some brass inserts in the 3d print. It would be super solid, depending on how the print is mounted. I think the weak link at that point would be the print-to-dash interface.

I would just stick the above to the dash using 3M tape. No need for the printed platform.

We'll see if we can manage to not invoke the name of Zorba here, but mounting my phone near the A pillar seems to be inviting a phone+roadway meeting of the minds. The mount may break, the magnet or holding mechanism might not be enough for that curb you just hit at the mall, or you might just be a few car lengths ahead of @macleanflood's wife when she gets distracted by livestock*.

Sounds like there might be some lore here, care to share @macleanflood?
