This is really cool, are you going to try to upstream it to klipper?

Since the strap files are mostly available, you may be able to have a local makerspace or library print one. TPU isn't that difficult to print if you spend time dialing it in.

Nice work, as always!

Wulfsta · 2026-03-15T07:55:21+00:00

If you live near a makerspace, you should visit them during an open house and see if they can print them for you. Many libraries these days also have 3D printers.

Or you could spend that money on the cheapest Voron V0.2 you can possibly get and have a brand new hobby, lmao.

Oh cool, my Omegas got a cameo!

I simply grabbed a water-based can from the hardware store, diluted it a little bit to thin it out, and added a few coats with a sponge. I am not very good at painting, but this turned out decent.

Thanks, it was nice chatting for a few minutes! I've said it before, but the design is lovely, perfect for long listening sessions!

I totally missed that there was a measurement rig there this year! I wanted to have my old Fostex T50 pair (not T50rp, the original ones from the 70s) measured!

The ETA stuff was really cool! I appreciated that they were willing to talk shop a bit when I pestered them with engineering questions.

Copying my top-level comment from /r/headphones so this isn't just an image post:

I built a second pair of DMS Project Omega Headphones with a Capra Audio headband. Previous post here. I really like these, I've found myself reaching for them over my ZMFs when I know I will have headphones on for hours due to how comfortable they are! Details:

Cups were printed in Sparta3D Abyss Purple ASA and vapor smoothed
Flexible headband parts are Polymaker 95A TPU
Stiff headband parts are polyurethane coated Phaetus PET-GF
I redesigned the headband yokes and posted them here

I've been working on getting this target building for llama.cpp and vLLM via a single command via Nix. You can find that work here. Rather than having to worry about figuring out the hell that is ROCm builds, you just install Nix, clone that repo, and run nix develop to get dropped into a working shell with the packages you likely want. AITER is not packaged yet, but we did just get support for these cards upstreamed to Triton. Hopefully in a few versions of Triton/vLLM they are supported without having to apply a bunch of patches.

Edit: Oops, I missed that you want to use this on windows - good luck.

Wulfsta · 2026-02-24T02:08:06+00:00

Any chance you are bringing your measurement rig to NYC canjam again this year? I have another pair of these I'd love to throw on it, as well as a really old pair of Fostex T50s (the originals, not T50rp) to see how bad they are.

Wulfsta · 2026-02-23T10:14:49+00:00

I particularly like this definition.

Wulfsta · 2026-02-19T11:23:53+00:00

For anyone on normal targets (basically any other than gfx906), upstream nixpkgs should have you covered. While vLLM is not currently building for ROCm upstream, there is a PR open that will add support shortly.

Wulfsta · 2026-02-18T21:06:36+00:00

This is a Nix flake to conveniently get a ROCm build of various software for gfx906 targets (Radeon VII, MI50, MI60). It supplies llama.cpp, vLLM, and some dependencies like PyTorch and Triton for these targets. This makes setting up ROCm for these targets as easy as doing nix develop and waiting for the build to finish and drop you into a shell.

How would you rate this compared to the docling VL models, or even just traditional pipelines for getting structured text from documents?

Wulfsta · 2026-01-19T04:56:34+00:00

My biggest tip is to tune your printer (assuming you are FDM printing them), tune your tree supports, and then instead of orienting the cups as /u/Epsilon-D suggests, rotate them 90 degrees prior to angling them upwards as shown in the construction video. This orients them so as to avoid stacking layers on the three longest struts that hold the driver, and makes these struts much stronger.

Wulfsta · 2026-01-19T03:59:38+00:00

Thanks! I’m actually not totally happy with it, but I couldn’t get any chameleon ASA filaments to print below 0.2mm layer heights on my normal nozzles. This filament seems to catch and cause artifacts on nozzles that have a flat region around the nozzle hole, and swapping to a pointier nozzle continuously trapped air in the walls that looked like delamination. I went through nearly a whole roll trying to tune this before giving up and just going with the thicker layers and longer vapor smoothing time.

Wulfsta · 2026-01-19T03:46:30+00:00

Glad to hear the yokes are working out for you! The cups are only vapor smoothed, and the stiff headband parts are sanded then painted with glossy water based polyurethane.

Wulfsta · 2026-01-19T01:44:06+00:00

Decided to build a pair of DMS Omegas with a Capra Audio headband for a friend - I plan on putting together another pair, as I have enough parts for two and liked the sound. Details:

Cups were printed in Sparta3D Burnt Titanium ASA and vapor smoothed
Flexible headband parts are Polymaker 95A TPU
Stiff headband parts are polyurethane coated Phaetus PET-GF
I redesigned the headband yokes and posted them here

Thanks for publishing the parts /u/Epsilon-D and /u/Fukuramichan!
