Helmet Hook

So got it mounted up using just the screw that came out of that location. After looking into that location and it being plastic I’m not sure I want to chance altering how the tail is somewhat held together. May look into a longer screw just to take up the extra space in the material but it’s pretty solid!!
I’ve got some extras too!

Are you looking to sell the extras, or mock up more to sell?
 
Thank you Del !!!.....Someone is sending me a set of hooks that has told me you had everything to do with putting the design together. So I'm going to be the recipient of some of your engineering genius. You are a very creative person, and you have mad skills.:beerchug:

Someone else, on the other hand is sending me these hooks. Thus, I have a major responsibility to pay it forward or pay it back. Just tell me when and where. :thumbsup:

Can I get them in that funky green of yours?. That'll look really impressive against the new color.:rolleyes:

Anytime and thanks! Just be careful and test first to be safe.

I need to focus and finish one task, before starting another. Feel like a kid in the candy store with any new (to me) vehicle.

I did print a PLA one with 100% infill last week and put a single coat of epoxy on it while I had some mixed. Completely forgotten about it till now, it's still sitting in my vice. I'll get it hung outdoors after work with some weight. I'll give printing again another shot.

I will finish this up before I tear the bike down and will most definitely share the STL to anyone. I think it's pretty much ready to go as is, just a matter of seeing how the plastic actually holds up to heat with weight on it.
 
This is pointless, but it's PLA with epoxy. Little over 4.5lbs hanging and faces north so always in the sun.

PLA or PETG, neither will likely break clean as a helmet hook, but in high heat they could soften and bend. Thinking out loud... if you have the cowl on and this does happen, assuming hook is long enough, it'll just bend up and hit the bottom of the cowl and stop. I don't think it's drop a helmet even if it does fail?

Melting temps...
350degF for PLA
500degF for PETG

More I think about it, with angle of helmet as it hangs off the hook, it may not have enough leverage to really put any pressure/strain on the trim screw to be concerned with it.

so the cowl holds pressure on chin strap you can almost just use the strap and buckles to hold it. the hook is more of a stopper. Only part that concerns me is the leverage.
 
You guys keep testing and making changes to get this thing better and better!
I have an 80% infill on the bike now and a 100% infill on the desk. Florida heat hasn’t really turned on yet but I’ll keep you guys posted.
I can’t tell the difference between the two infills. The mad scientist has some teenage big brain explanations on the two. I just nod and get ready to wrestle him. That’s how I thank him. Lol
 
More I think about it, I don't think there's any issues with using the trim screw. Still debating, but found this on my SLC forum that is informative about pros/cons of the threaded inserts. Would like to hear some feedback if people think these are actually needed or not.

Attached are 2 STL files using the OEM trim screw as well as one for the sockethead bolt if using a threaded insert. I take no responsibility if you print them, but if you do I'd recommend printing in PETG with 100% infill to be strong and heat resistant.

I’m surprised a ready-made solution has not come to market yet. I just ordered This retractable cable lock. As an added bonus I should be able to pass it through my jacket loop so I can secure that to the bike when I take it off on hot days.
 
Anyone have a couple of these hooks for sale. Tbh I don’t have much time to fab one up. Let me know. Metal. 3d printed. Doesn’t matter to me tbh. Just want it to secure helmet while I’m in the store or things or that nature.
