Progress at last on the airship envelope. I'm making a model in #FreeCAD of the airship from Splinter Town Fall.

I had some trouble making it hollow, then cutting the windows. This is my fourth attempt. When I abandoned attaching the window outlines to the model faces (as shown in every tutorial), things stopped breaking!

I have the engine nacelles ready to attach, but first I'll work on the interior - I'm hoping to find a program that will let me walk through the whole model. Attaching a hundred and twenty 60,000 cubic ft gas bags to an internal frame is going to be interesting...

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...).

Replied to FreeCAD

@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.

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.

#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.
