I make stuff.

[Jonathan VanBuskirk @VAT_Engineering]

I sort of made a bipod.

[Jonathan VanBuskirk @VAT_Engineering]

@Atlas_Leather 5 pieces?!

Protein maxing.

[Jonathan VanBuskirk @VAT_Engineering]

@Luth_AR_LLC @ThePanForFrying @BrownellsInc @AT3Tactical @FreemanAA68 @weaporize @DocStrangelove2 Odd question: what about +P rounds?

[Jonathan VanBuskirk @VAT_Engineering]

@Atlas_Leather Clone wars though....

It would have to come in black, with a lid.

Otherwise it would clash with stormtrooper armor. 🤣

[Jonathan VanBuskirk @VAT_Engineering]

@benheck That's because the handle is over the wheels, you don't have enough leverage for the spinny wheels at the front.

[Jonathan VanBuskirk @VAT_Engineering]

@Atlas_Leather Hubba hubba.

[Jonathan VanBuskirk @VAT_Engineering]

@3DPBelgian @Prusa3D And isn't bambu slicer a fork of prusa slicer?

[Jonathan VanBuskirk @VAT_Engineering]

@politicalawake Can we just not destroy historical sites?

Let's not appropriate cultures that wish to destroy history that doesn't agree with them.

Saw some English graffiti in an Asian country and it frustrstes me that such things change his people see all Americans.

@i2cjak Don't get me started.

ITAR doesn't matter when it is just a fee, it's just a cost of doing business.

While small businesses are raked over the coals for even thinking of legally procuring ITAR restricted things.

@RepPatHarrigan 100%

Right to repair or our own government is subservient to defense contractors.

[Jonathan VanBuskirk @VAT_Engineering]

@themitch22 @geerlingguy @BackwoodsEnginr I'm arguing for a more diverse supply chain for a sub-line of printers.

Source parts from Taiwan, Portugal, even Italy (some electronics) to save on cost, try to make it competitive.

Unlikely it will ever happen, but it's a case I'll continue to argue for.

[Jonathan VanBuskirk @VAT_Engineering]

@CanuckCreator @geerlingguy @BackwoodsEnginr @Prusa3D Electronics alone are the majority of the price if I recall correctly.

They need to line up a solid supply line with other non-China countries.

They could seriously sell a mini printer for $399 that outperforms almost anything in its class.

[Jonathan VanBuskirk @VAT_Engineering]

Jeff speaks the tru tru

We need a user friendly consumer printer that people can afford.

Especially one that doesn't sell your data too.

[Jeff Geerling @geerlingguy]

@VAT_Engineering @BackwoodsEnginr I wish they'd bring back the Prusa Mini, but like a Voron mini, but like this: https://t.co/ain5CJxRmG :)

[Jonathan VanBuskirk @VAT_Engineering]

They need to put @themitch22 on the case!

I own a whole army of prusa minis, not for a farm but because they're awesome! Best printer idea they had, compact for shipping, user assembly in minutes, (initially) low price.

It would be the best selling printer ever if they let Printed Solid optimize it for manufacturability (including opting for lower cost controls).

One can hope.

Unfortunately the core one mini community project never really saw any support from Prusa either.

[Jonathan VanBuskirk @VAT_Engineering]

@GrandpaRoy2 Tried to get a project going for that in the USA.

I couldn't convince people to use cheap fiber optic lines over a massive proprietary relay radio system that is unrecoverable.

🤦‍♂️

[Jonathan VanBuskirk @VAT_Engineering]

@CooperZurad Process optimizations.

But also, materials and equipment are outrageously expensive in the US.

Wish there was a way to solve that at lower levels.

[Jonathan VanBuskirk @VAT_Engineering]

@jakkuh_t @Prusa3D A gaming computer with a 5080 is cheaper.

[Jonathan VanBuskirk @VAT_Engineering]

@geerlingguy @BackwoodsEnginr The primary issue for average consumers is price.

$900 flagship 4/5-color Bambu VS $2,000 single color Prusa.

Prusa has become complacent in areas that make it hard to scale and manufacture efficiently.

They lack a consumer-facing printer.

[Josef Prusa @josefprusa]

BambuStudio has been violating PrusaSlicer AGPL license since their fork, with the same networking binary black box in question today. Why are they willing to burn the goodwill over it?
There's something most have sensed but never seen it all in one place, the five-law framework China built between 2017 and 2023 ⤵️

So maybe their hand is forced as their "network" is too valuable already? Each law on its own, interesting, okay... Read them together, and add any Chinese company with big reach to the mix you get the complete picture.

1) National Intelligence Law (2017)
All organizations and citizens must "support, assist, and cooperate" with intelligence work. The same law makes it illegal to disclose that cooperation happened. Cooperation is mandatory, and silence about it is mandatory too.

2) Cryptography Law (2020)
Commercial encryption must be state-approved and state-reviewed. When authorities request it, companies must provide decryption keys or plaintext. The state on both sides of that equation is the same one.

3) Data Security Law (2021)
Article 2 gives the state extraterritorial reach over data that touches Chinese national security or public interests. So EU/US data hosting does nothing to make it safe, because jurisdiction follows the company, not the server location.

4) Counter-Espionage Law revision (2023)
The general definition of espionage was expanded to cover "documents, data, materials, or items related to national security and interests." Industrial data is one of the intended targets since the revision.

5) Network Product Security Vulnerability regulation (2021)
Any company or researcher that discovers a software vulnerability must report it to MIIT within 48 hours. From there it flows to CNNVD (China National Vulnerability Database of Information Security), operated by the 13th Bureau of the Ministry of State Security. Microsoft's threat intelligence team documented Chinese state-hacker zero-day usage rising after this took effect. Shows the willingness to use the “tools” China built.

Together they describe a system with no neutral exits. Cooperation is required, encryption is real but the spare keys live at the ministry, jurisdiction follows the company across borders, industrial data is in scope, and discovered vulnerabilities flow to an intelligence agency 😬

3D printing became strategic for China in 2020 and joined the “Made in China 2025” plan soon after. Why does 3D printing matter so much? 1/x
