I’m currently printing this. Will report in about an hour.

First attempt failed due to poor bed adhesion. This material is crazy difficult to work with! Will reset and try again. I’m also having issues with this new spool being improperly wound. They must all come from the same manufacturer and have different brand names. Sheeesh.

Print complete! It’s a bit messy but it looks good. Waiting for it a cool a bit before I pull it off.

I have it undergoing the annealing process right now.

I’m going to print another set in ABS, anneal that. And then send it off for real life testing.

How can I get set from you sir!? I had made a Mickey Mouse set with some burnt h4h onto my led (I took the rings off lol) but this you have is where is at!

@clumbz Stay tuned here. I want to make sure they work first.

White is PA6-GF, black is ABS. This is with 0.6mm nozzle so the finish is rougher than I’d like. But it fits.

I have a feeling it will! I have some auxito h4 on mine

Hey I just saw this, myself and a few others are also interested in getting a set. I see you’re still in the process of testing. We would love to help out lmk!

Glad to hear the interest! I want to print a few more over the next few days to test a better printing technique and then anneal them again. The locking tab is really difficult to use right after the print and required a lot of sanding to work. I’d like to fix that so bulbs can stay at the correct orientation without any manual sanding being necessary.

Hey nfulfx hope the testing is going well, i also have some one piece headlights and boslla bulbs like someone else in this thread. I am incredibly interested in this adapter and will definitely do testing with these bulbs. I just cut mine up trying to make them fit and destroyed them​:sweat_smile::sweat_smile:. Let me know! I can get specs with some calipers if needed!

Dimensions would be great. I need the lengths in green, in millimeters. Please use calipers. Additionally, I need to know whether your bulbs have locking tabs: one should be wider than the other, and they should be 180° apart on the bulb housing. The wider of the two is shown with the red arrow.

The high temp material is still proving to be cumbersome so I’m focusing on the ABS because I can get a clean surface.

I bought a specialized oven to anneal more parts at a time (7 hour process). It arrives tomorrow.

Got those measurements for you. No locking tabs at all.

No locking tabs… How does it stay in the correct orientation? Did you get any instructions with the bulbs?

Yup no locking pins it seems its all done through the base that can be twisted off.

Okay interesting. Thanks for explaining. If many models are like this, it certainly would remove any mods I’d have to do.

yessir glad to help, do you think you will be printing any more soon? id like to test them on the boslla bulbs and return some feedback. it might help the others with these bulbs.

I should have a spare set of LEDs I can get the measurments from them as well I just need to locate them first.

I printed an updated “strengthened” version in ABS last night using a new support design and I was very happy with how they turned out. My plan though is to print these with the high temperature filament which requires a different process, but at least I know the new support works great and leaves a clean surface once removed.

I think the annealed ABS will have better heat resistance than un-annealed, but I think it still won’t last as long as the high temperature (glass fiber) one, as @LabOps suggested earlier. I may offer both types and give members the option. The high temperature one will easily be double the cost though.

I had a dream that I printed these last night. Should I be concerned? LOL
