My son had designed some 3D items. Any thoughts on what he could sell these for?
Pill cover. There’s a magnet inside to help keep it attached.
Throttle cable holders and fuel line holders. The clamp to the chassis rail.

I’ve no idea what they cost, but a cool value add would be custom designs for the caster caps. Logo, name, smartass statement. Might even entice people that otherwise would not bother to cover their kingpins.
Imagine if you could carbon fibre it
Carbon fibre steak knives. Japanese blades.

Oohh !! Count me in to it sir !! About the Japanese blades of course!!
Gary Carlton has 3D printed “brake fans” which go around the hub and inside the wheel rim for front tire cooling…
I’ve printed some. Will be trying them shortly. I don’t think kart wheels have enough open area to really flow air, so we will see.
would you be willing to send some of those wheel fans to others (me) willing to try them for their shifter?
Sure can! I just need a couple hub/wheel dimensions. They will just slip fit over them with a M5 cap head and nut to hold it together. You can easily see GFC printed it with a split.
One of my absolute pet hates is slop between the steering shaft and the bushing. I had a wild kart with an insert like this that helped.
My 3d printer has stopped reading memory cards so
I’ll have to address that first before I make anything, but I think that’s the next thing I’ll whip up to sort out the slop on my rentals.

I had to put my old DIY printer out to pasture. The latest crop of “cheap” printers are just amazing to what was even available for $2k plus maybe 5 years ago or so.
Thing absolutely rips and the quality is so good versus what I’m use to for a 3D printed part.

I wonder if a centrifugal style impeller setup would work better to draw air from outside to in with the exit being around the bead radially. 
Yea I’m not sure if pushing or pulling air through the wheel is better. The GFC design to me doesn’t look like it would catch much air being mostly flush with the rim.
Yeah that’s why I wondered about the centrifugal design. Centrifugal fans are better for static pressure also so may draw a better vacuum to suck air through the small holes that are in the wheel. Just a theory.
I needed a cradle for an air filter, so drew one up and printed it. Looks like it should do the job. Maybe I’ll print it up in some carbon fiber filament in the future, but I’ll give it a go as is and see if it needs any refinement first.

Pretty happy with the carb slide holder. Took a bit of tweaking to dial in the threads so it all screwed together.

Having played around with this the past couple days, I think I’m going to go the turbofan route.
There is just not a lot of real estate to make it happen on the inside of the front wheel for a shifter setup. Also I think it’s the better performing design (no math, just intuition). Just need to come up with a clever way to hold it inside the wheel. Also this should be a matter of modifying like two dimensions to make it work for the rears. Ideally it performs well sitting flush with the wheel face for a nice drag reduction effect as well as not forcing you to narrow the rears for track width rules.
For now on a super quick flip through some rulebooks. I don’t see anything saying there can be something attached to the wheels or hubs.
I’ve toyed with these kinds of designs too. What do you think for connecting:
- connection to the stub axle (1 nut)
- connection to the hub (3 nuts)
- to the wheel, maybe via the bead retainers
