Also, I could be wrong but this project sounds like it has an index optimized for bi-temporal data, useful for audit purposes, eg "what was the exact state of the db on september 12th". in neo4j you would have to add that information as indexed properties on each node and edge in addition to other indexes. not sure about the actual performance differences here but I guess one could structure the data more efficient in the first case for time sensitive data usecases.

looks like an attempt to create efficient agent memory.

There are mainly 5 friction points I have experienced with the 3MF file format used for 3D printing:

    Slicers store their print settings in their own specific ways which locks in users in respective ecosystem.

    There are vulnerabilities with the 3mf file format, as listed in this article.

    3MF files are a bit clumsy to do simple inspections on. lets say i want to look up what "infill pattern" is configured. I either have to spin up a heavy slicer software to inspect it, but that experience doesnt come with full transparency. Alternatively I can rename the file extension to .zip and unzip it, then look through the individual subfiles with a text editor, which directly causes a messy download folder on my computer.

    sometimes i want to export STL files of individual meshes in the 3mf file.

    meshes can be non-manifold

It also has an git inspired change log, where you can inspect and revert changes you've made to the file.

It also has a tab called "My Hardware" where you can save all your printers, filaments, nozzles, beds, and calibration profiles. Which then gets auto picked when you convert files.

It's free, no account needed, has no trackers, has no ads, and your models stay in your browser.

Not saying its impossible to create a successful system like that, in fact it sounds sort of a natural/organic design that potential could be closer to the optimal design, but it would be more difficult to accomplish and probably need more testing and design iterations. So I think OPs strategy is more simple and pragmatic in this case.

How on earth can that be faster than typing on a regular qwerty keyboard.

I just like to challenge myself, as an engineer, with the idea that not everything has to be engineered and optimized. What if we simply left some things unexplored and mysterious, and trusted nature and our own human capabilities?

A better way of alleviating psychiatric/mental health disorders might just be to focus on societal factors.

For what purpose? To replace humans? To make social media more addictive? To master brain manipulation?

I think one major advantage of open source over commercial alternatives, is the possibility of endless improvements. Similarly, 3d printing as a manufacturing method allows for a short iterative cycle, high degree of design freedom, customisation as a product feature, local production, and an high degree of repairability.

It’s going to be interesting to see how well git(hub) and discord serves as collaborative tools in this case. Hardware files are often binary, hardware components have complex interfaces between them, and hence depends more on human communication and collaboration.

I really hope this project succeeds. I’d love a cloud free robot vacuum that I can trust.

I’ve saved up a couple of months of salary, have a couple of bootstrap ideas that I believe are within reach for me equipped with a coding agent to build. Hosting can be done almost for free. What used to take entire teams and hence millions of dollars to build can now be done a lot cheaper. If I’m lucky one of those ideas can pay my bills soon. If not I’ll go back to consulting for a couple of months.

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

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.

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

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.

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
