All I am saying is I don’t like these particular solutions.
Doesn’t mean others should not follow that path.
It is just my opinion, nothing more.

Brackets look great already good job! Planned to buy gbomb adjustable brackets but these might be better and cheaper for what I want 
Also printed a simple bracket to see what it would look like on the jet potato 29inch.

Simple, solid, steel adaptors at a set angle is where I hope this goes. Time will tell.

Tell me you stood on it juuust to see.

Just an idea, use sheet metal parts in steel, bend a flange to make a open hem downwards, weld, to improve brackets stiffness and reduce cost. Also this will be better for fatigue I guess

Would have made a dissapointing cracking noise if I did… it was printed with just 1 perimeter and 15% infill, could pretty much break it with two fingers if I wanted 
I think it is possible to 3D print a bracket but It would need to be a strong material and be very well designed. Even then I would probably not trust it for going faster than 15mph lol

Like multiple thinner sheets of metal?

The three "D"s in 3D printing affordable structural parts stand for Dumb, Death and Destruction :). Carbon printing could possible approach the requirements but I don’t think we are there yet

I was thinking the exact thing this morning @jack.luis, several thin gauge members together would be amazingly strong. Possibly interleaved with urethane or epoxy for a metal composite. I see very high fatigue strength with this. Would need mounting holes drilled after assembly but I see some definite advantages in this approach including the ability to bend a tighter radius bend angle!

Not that thin, just thinner than the alu on the drawings as of now. And bend it in the correct angle, then fold a flange along the length of the two flat faces, connect the two flanges with a weld. I will draw it out later if I get the time 
and powder coat black. Done deal 
hehe

Thanks @Mikaelj , I understood what you were saying but I would like to avoid the expense of welding if I can as well as precision cut and bend to do the quality I am looking to do.

How so?

I might give this idea a shot myself
I’m looking for something similar… A super stiff short board for easy battery mounting and a bit of springy suspension at the truck mounts to help absorb road shock…

@speedboard is 3D printing their swingarm, so…
FWIW I still like @kook’s 1040 spring steel idea better.

This is not really suspension in my mind, the handling would be a bit unpredictable since as it actuates, your effective base plate angle increases causing the board to turn more when compressed.

I’d like to see you bending a short 5mm thick piece of spring steel.
Effective truck angle would change, obviously under compression, As all trucks do on flexy boards…
In my mind I’d preload the bushing to allow 3-5mm of compression at the king pin which would allow more movement at the wheels…
