I finally finished this custom USB Controller using a 12 position switch. The customer will be using it as a USB MIDI Controller where they want to select 11 different settings.

It's a bit taller than I'd like but the switch is pretty tall and I need a certain amount of space for the PCB and controller.

The enclosure is 3D printed and so is the knob. The multi-color prints for both came out great.

Why not both‽

  • The #FreeCAD #OpenSCAD workbench lets you mix and match. A friend sent me an OpenSCAD model of a part he wanted me to machine. I used the FreeCAD OpenSCAD workbench to show his model and then used TechDraw to make a drawing to work from.
  • FreeCAD's Part workbench is basically a similar CSG workflow to OpenSCAD, with boolean operations on shapes that take parameters, so a preference for working that way, or problems that fit that model, shouldn't drive a decision either way.
  • Actually, design-as-code works in both OpenSCAD and FreeCAD. FreeCAD has been a Python library and allowed you to write custom code driving basically anything in it in Python forever; I've written custom macros for multiple purposes. And in recent development builds, OpenSCAD added the ability to use Python as well as its bespoke language.

#OpenSCAD advantages that I care about:

  • Code. git diff is more meaningful (though it's possible to make it somewhat meaningful for FreeCAD)
  • Affine transformations (wow I miss this sometimes in FreeCAD!)
  • The OpenSCAD Cheet Sheet — if you think in code and CSG, OpenSCAD is remarkably easy to get started with. When I first started with my 3D printer, this got me up and running in minutes.

playing with #openscad (lots of fun!) lead inevitably to having to get the printer working after a long break of downtime. I have PTSD from early days wondering how anyone ever got anything to print before #3dprinting became routine. Hoping the printer still remembers those days.

Inside of a 3-D printing bed, spool filament on the left, mirrored print surface. Just starting on printing the base.

Last April I broke out a bunch of internal #OpenSCAD libraries from a project I'm working on into their own library set. I just made an update to one of those libraries, the collection of decoration and arrangement modules in openscad_annotations, that I'm pretty jazzed with.

Da ich eigentlich auch gerne die BMS-Daten hätte und Bluetooth, naja, halt Bluetooth ist, jetzt noch ein Mount für so steckbare Schraubklemmen um RS485 und Schalter vom BMS anzuschließen.

Passt ins Akku-Frontpanel wo vorher 2x RJ45 waren und lässt sich komplett von Außen einfädeln und festschrauben (die Mutter drückt einfach von innen gegen das Frontpanel)

(das Gedruckte ist die erste Version)

Foto der Akku-Frontblende mit drei Ausschnitten für RJ45-Buchsen. In der mittleren steckt ein 3D-Druck-Teil, in dem die Buchse einer steckbaren Schraubklemme steckt. Das Teil hat an der Kante des rechteckigen Ausschnitts jeweils ein Loch für eine Schraube.
Selbes Foto aber mit eingesteckten Schraubklemmen
3D-Modell der Vorderseite. Die zylindrischen Schraubenköpfe sind hier versenkt, und die Pins mit "A", "B", Ground-Symbol und Ein-Ausschalt-Symbol beschriftet.
Selbes 3D-Modell von hinten. Vorne ist ein Rand, der gegen die Frontplatte drückt, darunter ein kurzes Stück mit den Maßen des Ausschnittes, dann ein dünner Rahmen um den Stecker herum mit Löchern. für die Pins.
