I created a 2d surface that I can perform a linear extrusion on, however the result it obviously a hard edge on the extrusion. I would love to be able to add a bezel - either rounded or at 45 degrees. Is there an easy way?
I’ve got the basics down, but now looking to do something more complex, and unsure if it’s possible. I have imported a flat shape (a pcb), and I can extrude this out. What I want to do however is to rotate it on its axis, and then extrude it down the z-axis (not directly out from the surface). Is this possible, and if so,...
I’ve been printing sculpted palm rest prototypes in ninjaflex, because i had some on hand, but if i were you I’d buy ninjatek’s Chinchilla. 75A and tested for skin compatibility.
i think its a reasonable idea, the TPU seals in air so its like a pool inflatable. TPU likes lower layer heights and you can get away with 5% infill but any less and the top surface will have holes in it and loose that pillowy feel. might need to go higher for a smoother surface. I recommend a non-crossing infill (otherwise you get blobs on the nozzle that will ruin your surface feel) and one that alternates directions, rather than stacking lines, so that the infill has more give. i tried gyroid at first, but 3D honeycomb was noticably softer because it alternates.
also, avoid sharp edges and corners in your design and slope the sides, don’t have them vertical. this will also increase the softness
I’m currently designing a hot-swap hub+spoke keyboard, and I’m thinking a little ahead about the gaming keyboard module. I’m considering using a thumbstick instead of what would be the WASD cluster, alongside ample surrounding keys for RTS and other such games that have big hotkey configs....
you can 3d print an adapter to place a thumbstick in an MX keyplate socket. and keycaps. 5 way switches tend to require more force than regular keyswitches, but a longer stem will offset that.
Many years ago I had a ThinkPad and I had such a nice workflow using the track point. I had good precision without having to move my hands. Now I’ve moved to a split keyboard (kinesis freestyle edge currently) but I’m wanting to get something similar back....
I’m thinking about printing my own Dactyl exactly to my measurements but I don’t want to print too many iterations before landing on my preferred layout. Any tips on how I could achieve that?
my suggestion is to use a skeleton-edition style case so you print the minimum amount needed, and reuse the base plate. ie print only thumb plate til you get the position close, etc.
trying to link the keyboard parameters to measurable features of your hand helps some, but honestly there’s no substitute for typing on it and realizing what you don’t like :)
i’ve has a recent breakthrough (implementing hierarchical/delegated column placement) that makes merging multiple plates with differing centers of rotation just work when switching from an open case style to a closed case.
you could take my model and replace the cylindrical column spacing for pinkie and index with a flat spacing to have something less intense.
i don’t have a clone, but it would be easy to do, for the dactyl fingers. the columns have a standard spacing I believe and the rows are placed on a cylinder with some radius and and a fixed angle (π/32 radians maybe?). then you can either replicate the column and Z stagger they use or tune your own.
the DM thumb is actively bad for me tho so if start with a simple 3 key arc (i think there is a tester for the arc placement) and add and remove keys as you try it out.
Hiya all. I was wondering what pointing options there were out there for split ergo keyboards? Looking around, on the face of it there seems to be the Apple Magic Trackpad 2 and well that’s about it. There seem to be plenty of trackballs at various prices but nothing that looks particularly small and nondescript....
check out the santoku for a 40% split with trackpoint. otherwise there’s lots of custom builds with trackpoints. recently there’s an experimental zmk driver, etc.
