Does anyone know what file format they are storing the color information in?

Seems like the volumetric extension of 3mf files could support it. That would make cross slicer file mgmt easier.


I had a conversation with my industrial design teacher at university once about how slight ugly and uncommon design might have a positive effect on consumer demand over time.

I don’t know if there is a psychological term for that phenomena in design but I think it’s related with mere-exposure effect [1]. A design that stands out and is uncommon, will evolve a deeper relationship over time with the observer than a well-polished predictable design.

This is an uncommon design for a Ferrari, but this a very common design for commoners. What is more common than a Nissan Leaf? https://en.wikipedia.org/wiki/Nissan_Leaf

The problem is that the eFerrari looks like a slightly improved bog-standard $40k Chinese EV crossover suppository.

It's not all that ugly, it just doesn't really hit any Ferrari design language, or even do something interesting enough to justify the extreme cost.

”San Francisco mine” - is that a coincidence?

Clajjan is this you?


I’m building a web app that optimizes fdm 3d printing print profiles based on geometry, material, hardware etc.

Hopefully this can help people reduce filament usage and waste, speed up print times, and improve print quality.


Space Concordia, a Canadian university space-oriented student group, which is sort of amateur-level given that it’s driven by students and donations, attempted to reach space not that long ago with a liquid fueled single staged rocket. Here is a video of the launch https://www.youtube.com/live/610YciEs8qg?t=4594&is=aAWo8Y7vi...


Thank you so much for sharing this video, it's just amazing to see a bunch of young amateurs getting so excited about things that would have been virtually inaccessible 20 years ago.


It’s beautiful to see. They have put in such extreme amounts of hard work to get that thing into the air. Designing a robust affordable liquid propelled rocket from scratch is hard. There are so many design decisions, complex simulations, manufacturing difficulties, and tests for every little part of that 11+ m rocket. Accounting for extreme forces, heat variations, vibrations, wind, atmosphere, liquid sloshing, rotation, etc during ascent and descent. It’s not only mechanical/aviation engineering but also software, electrical, sourcing donations, documenting everything in forms of design and risk assessment reports etc etc.

You also have to try to account for every little possible failure mode before launching which is why rockets seldom succeed on the first attempt.

And then dealing with authorities to create new launch sites and permits which probably hasn’t been done in decades in Canada.


Indeed, there are so many different ways a rocket a fail. Launch rail buttons detach, motor chuffs, motor explodes, fin falls off, structural failure (banana), parachute doesn't fire, parachute doesn't deploy, parachute detaches - to name just a few.


thank you for the feedback, it totally makes sense to want those fetures. and yes, I've also seen that there are a lot of sites like that.

its tempting to implement but also comes with more complexities, which Im at this stage not that exited to hop on. I'm thinking of:

- need for a backend with login/authentication -> kills the endless scalability aspect of only having a frontend.

- there are soo many competing tools already existing. Im not sure what my moat would be.

- For me, as a freelancer with max 1 assigments per month so far, a standalone pdf-maker like this one is preferred over being locked in to a Saas product.

- in that case I would want support for e-invoices which seems a bit bureaucratic to get in place


Thank you for testing it and the feedback! I have added support for a second VAT row now (withholding VAT) which is negative. Let me know if it covers your needs :)


May I ask if your software is released and if so, what it is called?


As a backend development consultant, I lacked a way to automatically create time reports and invoices from them, so I created this tool.

- Automatic time reporting, very useful for consulting

- One page - very straightforward

- Ad-free

- No sign-up

- Upload existing invoices to auto-advance dates, invoice numbers, and time reporting

- Real-time preview as you edit

- Your data stays in the browser (no backend, except openstreetmap autocomplete)

- 5 different invoice types: regular, receipt, pro forma, quote, credit

- 5 different templates

- Supports complex VAT and discount scenarios

- 10 languages supported

I plan to keep it free of charge!

happy to hear feedback or feature requests
