Id be printing PET-HF. Was recommended by Gemini and Claude for load bearing on my H2C. 0,6 nozzle and 100% solid (or 0,8?)

I do not have an own 3D printer, therefore I used jlcpcb as service provider.
The first version I ordered PA12-CF material in FDM print, but I was not happy with the surface finish.
The Ullicyc adapters are made in MJF, so for the next revision I ordered MJF printed PA12S-HP.
I believe PET-HF is commonly recommended as well, but I do not have any experience with it myself.

Just noticed the Ullicyc T6 on AliExpress, that seems to compare to Hudud, Rpantahi and Yichord riser cokpits
As usual, Ullicyc offers MJF printed headset adapters

Well I received the Ullicyc T5 bar and that was a bit of a disappointment. The T5 does more or less give the same total stack to the hoods as the T4. I don't get how they make the drawings/specifications? Stem angle is especially important to compare in the same way. I feel it's a bit of a gamble buying new type of handlebars  and I will not use them. The T4 is better looking and much more stiff. Actually a really nice bar. Was hoping to be able to slam the T5 but no point. Will continue using the T4 bars for coming builds.

Sorry to hear that. I am also running the T4 on two bikes and I like them a lot. When I first saw the T5, I was excited for another option of riser bars.
I am quite tall, therefore everything that adds stack without a spacer chimney is appreciated to dial in bike fit.
The challenge with riser bar cockpits as it seems, is that there is no unified approach how to "specify" them.
Not even do you need to look at the drawings very carefully, some drawings (like the one of the T5) are just shite.
Even after contacting Ullicyc on AliExpress, I still have not fully understood their drawing - which unfortunately you confirmed.

Just came across the Ullicyc T5 on AliExpress

If aluminum is an option for you, forum members have built bikes with the Gas cycle (use search function)
There are also threads about Seaboard steel frames

Elitewheels Edge is available as rim brake version in 40 and 50mm rim depth, should tick your boxes and can be sourced via AliExpress
XMCS has the CS-RRW-50-28 or CS-RRW-38-28 as standard option on their homepage, note these are with carbon spokes

I am based in Germany and my AliExpress order on the Ryet Official Store was cancelled after it was initially accepted (reason: "issues with shipping") and refunded

Looks similar to Ullicyc T4 Ultra, I am running the T4 cockpit on two bikes and I am very happy with it.
Noticed Hudud started selling it as HB071, but I have not came across Yichord.

They all look similar to the Lightcarbon HBR017 but there seem to be differences as pointed out by other forum contributors.

anyone ordered these recently? curious about time until shipping. not sure if LC is struggling to meet demand only on frames or everything.

Aren't the Ullicyc T4 Ultra on AliExpress near identical to the HBR17?
Slight differences in the mounting system to the fork and cable routing ports, but the rest seems very comparable to me...

Where did you order Oniiri RH bars?

They are called HB 02 and Onirii Official Store sells them on AliExpress

The bikes with aftermarket riser bars, not sure if there is any real benefit.

I would like to think the aftermarket riser bars offer an optical benefit.
Slammed stems seem to be desired for look and social media, riser bars help combine aggressive / racy look and decent fit?

Might be worth checking with HY Bicycle Store on AliExpress:

ULLICYC T4 ULTRA looks similar to Lightcarbon HRB17 in shape, but has differences on computer mount and how it secures to the steerer tube
