Step 1. Never connect it to the Internet. Step 2. Connect Linux machine. Step 3. Profit.

Also 90-95% of print failures are due to a bad first layer (citation needed).

I saw that video, but I couldn't remember the name of the channel. Great channel though.

The best part is there are hand writing generating programs or even web pages that convert text to gcode allowing you to use a 3d printer to write things out. In theory it should be really hard to pass it off as being human written, let alone match your own writing, but I'm sure it will only get better. I think there are even models to try to match someone's writing.

your reference. Solidworks does have a point cloud tool but no idea how good it is. Working with surfaces in Solidworks usually is not hugely fun.

All I really need is to get the surface data into something other than a "mesh" format. My actual job is working with Catia V5, but my work does not have any of the applicable Catia licenses to directly work with mesh files (such as STLs). If I can get to that point I'm golden. I have plenty of experience working with and creating surfaces.

FreeCad can apparently make a step file from meshes with a few steps, but when I did that with a simple 1 2 3 block scan, the result was about 2.5GB's, and tends to lock up anything that tries to open it. I may look into an open source program to create usable surfaces from point clouds instead of trying to use meshes.

Well, this is with a RevoPoint Pop2. This is 2 or 3 scans merged into 1, no editing outside of the scanning software. I've been extremely impressed at how well this can scan and produce a 3D printable STL. The only thing I haven't figured out is how to get a file with the surfaces usable in CAD software. I can pull the STL in and see it, but not constrain it or create intersections with it.

For scanning, Epic Games has a phone app that I've seen seriously impressive results from just photogrammetry. I did not have very good luck with it, but it is definitely capable of great results. If you have a newer iphone, some of them have a depth sensor and apps available that can 3D scan.

If you want to scan primarily 3-8" objects the Pop2 is great. It's even at what are probably clearance prices at Amazon right now ($400-450 USD). I bought mine used/open box directly from Revopoint via ebay for $400. Definitely get the turntable. It is definitely worth the extra $50.

Yes lol. Souvenir from the dinosaur casting museum in Tucumcari, NM.

The top fin kept the details, and you can tell there were scales, but all the fine lines are basically gone.

Two more pictures of the original and copy(s).

I was playing with my POP2 3D scanner, scanned this toy fish of my kid's and 3D printed the resulting scan. I had to manually draw the spots on it, but really happy with how it turned out. Pictures don't do it justice just how exactly the same they are in hand. Not all of the textures came through though.

Wow this sounds a lot like my outlook with Ff7 remake. I begrudgingly bought it on steam when it was on "sale" for the still too high price of $40, and when it was good it was great, but other than one mission it is just the story of Final Fantasy VII up through Midgar with a stupid amount of boring fetch quests to pad the time. Saying it is maybe 33% fun engaging game/story 67% boring fetch missions or "go kill this boring monster" over there is in my opinion being very charitable.

It is my opinion that it should be legal to paint said stripes on someone's car if they park over the line. Should really hammer just how much of an asshole someone is if they have multitudes of stripes.

Disclaimer: I am no expert by any means.

With that being said, as others have said, a DNS is like a phone book. By using PiHole with it going to a privacy respecting DNS service, you in theory eliminate being tracked by a DNS provider, but you do nothing to prevent your isp from tracking which ip addresses you access, and you do nothing to prevent search engines tracking which results you click on, you do nothing to prevent your web browser from tracking your browsing (especially on Chrome and Edge).

In summary:

DNS lookups: yes

ISP with IP addresses: no you would need a GOOD VPN or TOR and either one properly configured

Web browser: no, you need at least Firefox with data collection turned off, preferably with something like ublock installed.

Search engine: no, requires more research but supposedly duckduckgo and eccosia are privacy respecting *citation required

Quite Operational (lemmy.world)

I'm afraid the Star Wars Memes, and the Fediverse, will be quite operational when our friends arrive.
