I 3d printed a custom sized keyboard using open source software and hardware designs. (lemmy.dbzer0.com)

The design is based on the excellent Dactyl keyboard, generated with https://ryanis.cool/cosmos/ and it runs the excellent qmk firmware. It is handwired:

and I have also made a palm support using inkscape and openscad

All printed on a reprap prusa i3 derivative.

This helps me use my computer with less pain, so I want to call out all the wonderful projects and people who contribute to them which made it possible.

Total cost? $60 aud, amortised filament ~15 bucks worth maybe? and a lot of my time haha.

Did you print your keycaps, too??

[–] synapse3252@sh.itjust.works 18 points 1 week ago (1 children)

I will always upvote split ergo (column staggered) keyboards. Nice stuff, looks much much cleaner than the one i made and threw out 😂

[–] naevaTheRat@lemmy.dbzer0.com 2 points 1 week ago

I have improvements I will make on my portable keyboard for lappy, but I'm never going back.

They're a lot more comfortable.

[–] Rooty@lemmy.world 13 points 1 week ago (2 children)

Man, 3d printing is punk as fuck, I love when people post bespoke shit.

Okay, Star Platinum.

Very cool! Can I crosspost to !mechanical_keyboards@programming.dev ?

Holy cow! I didn't know about that community, thank you!

[–] naevaTheRat@lemmy.dbzer0.com 4 points 1 week ago (1 children)

Nobody needs permission to post a link to something somewhere. What horror happened to you?

[–] Blaze@piefed.social 8 points 1 week ago (1 children)

Oh, I've seen it happen before, such as here: https://lemmy.dbzer0.com/post/45667427?scrollToComments=true

Thanks anyway, I'll post right away

[–] naevaTheRat@lemmy.dbzer0.com 3 points 1 week ago

There are always lunatics, you'd go mad trying to please everyone. It's one thing to not promote harassment. But if you put something into the stormwater drain of the information superhighway it's flowing everywhere with the rest or the shit.

You'd get further cursing the rain for falling on you.

[–] Imgonnatrythis@sh.itjust.works 5 points 1 week ago (1 children)

Super neat. What are those knobs for?

What kind of switches did you choose?

[–] naevaTheRat@lemmy.dbzer0.com 7 points 1 week ago (2 children)

Knobs are for knobby things. QMK is extremely configurable. Sometimes they are volume, sometimes seeking, sometimes mouse x and y, sometimes scroll wheel, sometimes keyboard arrows, mostly decorative.

MX browns. I am distinctly not obsessed with keyboards. I just like being able to use computers in postures that don't hurt.

[–] shnizmuffin@lemmy.inbutts.lol 2 points 1 week ago (1 children)

sometimes mouse x and y

The anti-trackball.

[–] naevaTheRat@lemmy.dbzer0.com 5 points 1 week ago

I have a trackball, but for pixel perfect placement etc. The knobs help me draw badly with more precision.

[–] Ajen@sh.itjust.works 1 points 1 week ago (1 children)

What did you program your knobs to do? All of the above?

[–] naevaTheRat@lemmy.dbzer0.com 2 points 1 week ago* (last edited 1 week ago)

indeed. Layers like an onion or an ogre.

[–] beastlykings@sh.itjust.works 4 points 1 week ago (3 children)

Very cool!

Honest question, does using a keyboard like this make you forget how to use a standard one?

I know op did it for the pain, so it's a moot point. But if I did it just because it's cool, and to avoid injury in the future, would I mess up my normal keyboard abilities?

[–] naevaTheRat@lemmy.dbzer0.com 7 points 1 week ago (2 children)

I also switched to colemakdh with a series of layers and qmk tricks. My typing is quite slow so far, around 30 wpm, I was never an amazing typist but I haven't noticed difficulty with standard qwerty layouts.

It's not like you get confused between a harp and a guitar, or a spoon and a knife.

[–] pupbiru@aussie.zone 2 points 1 week ago* (last edited 1 week ago) (1 children)

for me, switching to dvorak about 10 years ago has made me absolutely useless at typing qwerty… i get used to it after 5min, but much slower than i used to be and wow is it paiiiiiin (both literally in my wrists - the reason i switched, and figuratively in that i feel like im fighting the keyboard for every word)

… or perhaps you mean the differences in physical layout

[–] naevaTheRat@lemmy.dbzer0.com 1 points 1 week ago

I haven't noticed difficulty. Maybe because the layout is so different, maybe I will with time, or maybe I'm just ~~better than you~~ lucky :p

As someone who runs an ergodox ez with a custom key layout and who goes in to work from time to time using normal QWERTY keyboards (both English and German configuration), you do not lose anything. It's incredibly easy to switch between every config you have.

I also think most people would appreciate a split keyboard setup because it's so much better for posture and health and comfortability. Would highly recommend.

[–] beastlykings@sh.itjust.works 1 points 1 week ago (1 children)

Oh now this is different than I've heard, some others have had issues switching back and forth. So maybe I will give it a try, once I've got qwerty up to a decent speed and I feel comfortable with it.

Right now it's a problem because if I'm in a hurry, I'm tempted to type the old way, or a broken mixture of the two that messes with what I've learned. Not good. Gotta slow down and do it right, bah..

Thanks for the recommendations, I'm gonna put a 3d printed split board on my list of things I'll definitely get to some day and totally won't get pushed off the back of the furthest back burner lol

[–] gusgalarnyk@lemmy.world 2 points 1 week ago (1 children)

Lol. For context, it took me maybe two weeks to get back up to full speed on a new typing layout. When I moved to Germany they moved some keys around on standard qwerty and it took me a couple of days.

If you're already touch typing I think most changes are easy to adapt to and don't overwrite previous muscle memory. Your brain is powerful, believe it is and it will work.

[–] beastlykings@sh.itjust.works 2 points 1 week ago

That's good to know, thanks! I'm still just learning to touch type. I spent a few decades typing fast enough but always looking at the keys. This year I've started learning touch typing, I'm only a half dozen hours in, so still pretty new.

But when I get good I'll take this into consideration! Thanks!

[–] swelter_spark@reddthat.com 3 points 1 week ago* (last edited 1 week ago) (3 children)

I use Colemak on phone and Qwerty on desktop, and never think about it.

I love those keycaps 😍

Way cool. That looks really professional, too.

[–] naevaTheRat@lemmy.dbzer0.com 1 points 1 week ago

Thank you, if I have produced anything decent it is entirely owed to those who went before and were selfless enough to leave directions.

[–] SkunkWorkz@lemmy.world 3 points 1 week ago (1 children)

Looks so good. One day I will build a Dactyl as well, one day.

[–] naevaTheRat@lemmy.dbzer0.com 1 points 1 week ago

Pretty easy with that cosmos thing I linked. you can literally drag and drop buttons and shit. Pretty neat!

The most time consuming part was cleaning up the keycap prints as that involved removing support material and a brim for each. Soldering was around 4 hours work.

[–] TwoBeeSan@lemmy.world 3 points 1 week ago

Respect for your tism.

[–] Etterra@discuss.online 3 points 1 week ago

What the hell is this madness?

[–] wwwgem@lemmy.ml 2 points 1 week ago (1 children)

Very nice! That's a pretty big boy ;)

[–] naevaTheRat@lemmy.dbzer0.com 2 points 1 week ago

I don't have particularly large hands, but they're not small either. Most peripherals appear to be made for short people, but we grow tall under the searing sun of the land downunder.

[–] N0x0n@lemmy.ml 2 points 1 week ago (1 children)

On another note cause there are already a lot a good responses here and there :p.

How are your beavers doing? 😀

[–] naevaTheRat@lemmy.dbzer0.com 5 points 1 week ago* (last edited 1 week ago) (1 children)

Never ask a lady about her beaver(s).

My beavers have wet fur, and a variety of things to play on.

Reminds me of something from the Neverhood Game.

[–] vala@lemmy.world 1 points 1 week ago (3 children)

Too many keys

[–] naevaTheRat@lemmy.dbzer0.com 2 points 1 week ago (1 children)

Sorry your childhood sucked and you never learned how to talk like a decent human being.

[–] vala@lemmy.world 6 points 1 week ago (1 children)

Lol ok. First off, that wasn't mean.

Second, it was an opinion.

Third, it was a joke.

To explain the joke, keyboards with less keys than this exist and it's a common meme for people to comment "not enough keys" when people share images of them.

Thought this was a keyboard community. Didn't realize it was 3d printing.

The funny thing is that it's not even enough keys, you need to use layers

[–] vala@lemmy.world 5 points 1 week ago

Yeah that was part of the joke. Guess it didn't leave well.
