3d printed items useful for go karting

Annoyed at the price and design of some fuel line clips, I’ve designed my own. I’m happy to supply y’all if wanted. So far, seems great on my chassis. Will sell 6 clips for $10. PM me if interested.

I don’t 3d print anything, but would a helmet spoiler be practical?

Yes I’ve printed one for somebody. You need a pretty large format printer to do it in one shot in a good orientation.

ASA would be more naturally UV resistant and flexible, but if it’s going to be painted, PLA will be more rigid if high aero load or thin sections. It will be more prone to breakage. I’d use double-sided 3M VHB tape to attach. The other alternative is a small vacuum-formed piece of Lexan (polycarbonate.)

Mocked up some axle hub spacers. 5, 10, 15mm. Gonna test this weekend.

I now have a tall version of my fuel clamps also:

Decided to remesh a wing for the SK-6. Used primer filler afterwards to cover up printing lines and then sanded down.

2.5 MM 25MM spindle spacer.

This is genius, mind sharing the STL?

no prob.. send me a PM and I’ll try to remember to do it at some point. It’s on my friends computer. I’ll see if I can have him send it to me.

What a clever idea. Does that actually reduce tire temperature in a meaningful and useful way? Color me impressed if it does. Very simple, but very smart!

I apparently worked, but to what extent, I’m not sure. This falls into a weird in-between for me – 3D printing is so cheap they’re not expensive to make….but it’s tech that doesn’t need to exist for this sport….

Yeah, that’s like when F1 redesigns some 1" piece on the front and and its WOAAAAH LOOK OUT EVERYONE ITS A GAME CHANGER.

What I learned from racing with ex F1 designers and the guy who mentored me in karting is that 90-95% of stuff is just people trying to sell others and get rich. The best example of this was the 360 degree brake pad. Do you remember that Ted?

It was a 360 degree brake disc and the karting world started debating whether or not it was creating downforce. The idea was total BS and disprovable by a basic understanding of physics and rotational forces.

It may have had some cooling properties, but the gains would have been minimal and probably only seen by the top 1% of national level drivers. And then the question becomes at what cost. Blah blah blah.

Product never got off the ground and never went to market. I think it is up to us as a community to reject this stuff. When we don’t, others will mandate. Larger implications there of course. Good life philosophy. If its not broke, don’t fix it, and damn sure don’t let someone posing as a handy man get their grubby paws on it.

Stay off my lawn. And leave my karts alone. :smiley:

This?

Reminds me this plastic thing my friends has in his kart that supposedly gave you a little bit more downforce. It sold like hotcakes from what I heard, though I guess they banned it because I don’t see it anymore.

Might have been that. I don’t remember the name of the company it was years go. Pretty cool idea on paper!

And sorry, I didn’t mean to say the idea of the brake was BS. I meant the idea it was creating downforce was BS.

The duality between what is possible and what advances sport is always an interesting study.

Perfect for 3d printing. I bought a 2020 OTK and it has the bolt holes for that flap. I would 100% buy it if it was stocked anywhere :rofl:

I wouldn’t even 3D print this – I’d heat form some lexan so it’s clear, but also does the job… :slight_smile:

How week did the spacers work?

This sounds like the thinking some of our engineers on my old FSAE team had to try and gain us design points lol.

Yeah, there might be some merit in terms of allowing the pads to wear in a more even fashion, but the idea that it was creating downforce really shows you how far people will stretch reality in the sport of motor racing.

I think the best piece of advice I was ever given about cars was to learn some basic physics. If you understand even entry level you can avoid a lot of nonsense.
