TomVR Posted November 24, 2022 Share Posted November 24, 2022 The famous (and expensive) P1-1 OTTO Pushbutton, now replicated using a 6mm threaded tact button from Aliexpress and then 3d printed ring to go around it This is the exact store page I bought the switch from https://www.aliexpress.com/item/1005004689177372.html I've also updated one with a "hidden flange" where there is a 1mm lip around the edge and the tube is slightly undersized, for putting into holes where you want to glue it at the top and not have it fall through. (some B8 Grips) Here is the thingiverse page https://www.thingiverse.com/thing:5654238 2 1 Link to comment Share on other sites More sharing options...
rel4y Posted November 24, 2022 Share Posted November 24, 2022 (edited) Nice, that's exactly the same solution I came up with. Only I used the expensive switches from Knitter (MPS 103F) and printed the hat part as well. Now I am gonna order a bunch of these from Ali to test. Great work!

I wonder if there are different weights that exist in this form factor, option for a heavier switch would be nice. The red cap is exactly 1:1 to the dimensions of the P1 switch Cad model from OTTO I have, which was a very nice happenstance Edited November 25, 2022 by TomVR Link to comment Share on other sites More sharing options...

Maybe have a rubber tube under the existing button to give more resistance? Link to comment Share on other sites More sharing options...

Or a small spring, though neither of these help with the tactile report/click force Forgot to add this, but these metal dome CK switches make great internals for scratch built Otto replicas, very loud tactile click and 300gf force, the other 600.. combine with a spring/plunger in a housing the way TM makes them and it's a much more compelling switch than the mushy ones they make with the little dome switches in them. Here's a youtube vid I made showing it compared to another clicky CK switch that would also work well for the same reasons, depending if you want a sharper or duller report on the click Edited November 25, 2022 by Thadiun Okona 1 Link to comment Share on other sites More sharing options...

Oh no! The whole appeal of these kind of switches is the clean “break”. They barely move until they snap into actuation. So much more tactile and deliberate. A spring would just make it mushy and bad Edited November 27, 2022 by TomVR Link to comment Share on other sites More sharing options...
