This #FreeCADFriday, I am using @FreeCAD to design a 3d-printable laser optic mount system for interferometry experiments!
The main element are the kinematic mounts for precisely aligning all the optics. I have opted to use a flexure based design which required a lot of prototyping to get right (and there is still a lot of room for improvement...).

@FreeCAD I designed two OpenGrid tool holder for my workbench.

@FreeCAD My TV soundbar broke, because of a bad chip, so I wanted to repurpose the speaker parts, and the subwoofer, into a portable speaker. So I have been drawing up a "blaster" in FreeCAD with parts that will fit on my 3D printer. Biggest project yet. So far it is going pretty good. The amplifier I had unfortunately didnt work. So it is a bit on pause for now.

It's #FreeCADFriday! Happy weekend to everyone when we get there. What have you all been working on with #FreeCAD?
Forged in FreeCAD: CERN CMS Detector Cable Clamps
In case it passed you by, over on our mastodon account and on the X platform we have run the hashtag #FreeCADFriday for a long time. It's a straightforward "show everyone what you are up to with FreeCAD" type affair and every week so many amazing projects show up as responses.

@FreeCAD software has been vital in helping me design and build my own weaving loom.
Planning out the parts and measurements. And designing parts for 3D printing. The project is making great progress.
@FreeCAD I spent basically the whole #FreeCADFriday to model this ship and thereby pushing my skills to the limit...
The parts will be laser cut from wood and assembled by many kids in the @juzecrailsheim "Sommer im Juze" summer holiday program.
It contains a lot of spline curves and non-orthogonal shapes – handling them was kind of exhausting. The flattened shapes look awesome though! :)
Later on it will be turned into an RC model, but that's something for another day! :)
Today's #FreeCADFriday task: assembling the 3D printed case that I made the design mods to last Friday.
Turned out nicely.
#FreeCadFriday This has been my first full week using FreeCAD. I've made so many mistakes, so many retries, but also some progress!
I'm working on a model of the Zeppelin-like airship from one of my novels - I hope eventually to import it into a program that will let me walk through it.
Having some trouble getting rotation joints to stick, but here's a screenshot of one of the engine nacelles.
Happy #FreeCADFriday everyone! Hope you all have a grand weekend. Show us what you've been up too with #FreeCAD. #CAD #CAM #BIM
My contribution to #FreeCADFriday: A freshly designed bottom plate for the @dzoc #Datenzwerg|e in preparation for their deployment at #WHY2025. Will be covered by an off the shelf roof tile. The first version is printing right now, I'll show how it's supposed to work once I have it in my hands 
Following last weeks #FreeCADFriday where I made and #3Dprinted the spring loaded magnet base work clamps, I've today prototyped a micro probe idea. Again magnet mount, the next iteration will have one more degree of freedom in the arm. The probe is a stainless 0.4mm accupuncture needle insulated with some 0.6mm heatshrink! The board of course is an old #KiCad project. #electronics #freecad
A bit of #FreeCADFriday to add a couple of screws to fasten the two halves of the audio-level-shifter case (because my initial friction-fit pegs didn't handle the vibration of being mounted on a bike very well)
Just checking over clearances before sticking it on the 3D printer
It's #FreeCADFriday! Help us celebrate all things #FreeCAD and show us what projects you are working on! #CAD #CAM #BIM
