Since I don't have the matching GoPro adapter to attach my bicycle headlight to the new "cockpit", I designed my own custom mounting point in #FreeCAD.
It's basically just a round section (22mm in diameter, 21mm long) where I can attach the standard light mount to. Simple, yet effective. 
1: Idee
Die Idee, die Module als Überdachung zu nutzen, kam spontan, weil die Anschlüsse am Dach für mein Setup nicht passten.
Für die Skizzen habe ich #Excalidraw, #Blender, #FreeCAD verwendet und #Nextcloud für die Planung.
Die ersten Diskussionen zu Design, Größe und Material kamen schnell. Eine gute Skizze war dabei hilfreich.
Besonders geholfen hat mir das viele Kommunizieren und das Feedback erfahrener Leute, u. a. hier auf Mastodon!
Tutorial: Custom Toolbars
When you use any tool for a while you often build a more personal connection to it. Perhaps you have that old screwdriver in a drawer that’s become polished with years of use and fits your hand perfectly.In this tutorial we'll look at modifying existing toolbars and creating our own custom toolbars to personalise our #FreeCAD experience.

Oh, look! I made a thing!

Well this is looking somewhat promising. I think I can put the kinematic mount in a housing and center the probe tip in the lathe, then bore a hole in the housing that's colinear so the result is accurate.

Hm, in #FreeCAD I can successfully apply a linear pattern to a protrusion I have added to an object if I select the pad and configure it.
But is there any way to do a linear pattern including fillets?
Attached image is what I can manage to do by selecting the pad, but if I select the fillet it doesn't work.
I've tried searching web and utoob, no luck yet.
@requiem @IceWolf I'm always torn between CAD is just hard - I need to learn concepts, and #Freecad could be easier to use. It has come a long way, I'd give it another try. As a complete idiot who doesn't know what I'm doing, I'm sure I stress test it, but I certainly get lots of python exceptions just clicking around. The toolbench often feels like the EU - a bunch of things that hang out but really don't agree on how things should work together.
I miss Fusion 360. Are there any open source 3D CAD programs with decent UI?
Last time we tried FreeCAD was several years ago, but it was HORRENDOUSLY confusing. Ye gods, SO MANY TOOLBARS. Even Blender wasn't that bad.
Maybe it's better now, I don't know. Or maybe there's something else?
We know and love Blender, but I really like Fusion 360's "tweakable stack of edits to the object" model, and while Blender HAS modifiers, they're not really designed for modeling from the ground up that way.
I like being able to make brackets in fifteen minutes. These hold up some of the through spindle tooling for my milling machine. Designed in #freecad printed in PLA.
Mein 13jähriges Kind will ins #3d design für #3dprinting einsteigen. Ich halte #FreeCAD für den Einstieg zu kompliziert. Was haltet ihr von #blender3d ? Ich bin froh für Tipps, wie ich den Einstieg erleichtern kann.

Had a great session last night teaching #rocket design to 11 interested people of all ages! Showing off #opensource tools #Openrocket and the fabulous @FreeCAD rocket workbench. #FreeCAD
Lil Prusa Mini + earning its keep today printing some work stuff.. designs done this morning in the mighty #FreeCAD of course. :) #3Dprinting
What finally worked was starting from scratch in the part workbench and creating a body for each of those holes, doing an array of them in the Draft workbench, then doing a boolean cut.
Recomputes take seconds and not minutes; the file size on disk is cut in half; and memory is in the single digit gigabytes.
I would have never imagined that this would be less computationally expensive...but for some reason it seems to be the only practical way to model this design.
/end
Modeling this with a single sketch of all the holes led to FreeCAD using up >24G of memory and slowing my whole system to a crawl.
So I moved onto linear patterns.
Doing it in linear patterns proved to no longer eat all my memory, but every change would take 10 minutes or so to recompute the changes.
