For around $300, there are some newer models that are significantly better than an Ender 3. The Elegoo Centauri Carbon has been getting good reviews. I started with an Ender 3 V2, spent much of my time dealing with bed adhesion issues, then moved on to a Sovol SV06 which has a lot fewer issues and in some scenarios printed better than the Prusa MK4Ss I have at work. I recently upgraded to a Prusa CORE One, which is great, but I wouldn’t recommend spending the money if you don’t think you’re going to print much.

The website would have to verify the lack of a print photo. I’m guessing at this point it would probably be some AI image recognition filter so they don’t need to have humans verify all the uploads manually.

I would guess someone invented the handshake in prehistoric times and we just have no medium in which a record could exist aside from an undiscovered cave drawing or something like that. Humans seem to naturally touch hands outside of any social influence or cultural history. Babies reach out and people touch their hands. It seems like a pretty intuitive human action. We touch things with our hands, so other hands seems natural as a thing to touch. The shake just seems like a minor variation on that.

In the same way that Printables has an option to hide AI-generated content from the search results, you could just have an option to exclude models without print photos.

I’m waiting to get the new MMU for the CORE One when Printed Solid has them domestically in the US. I talked to a rep from Printed Solid and he said they should have them soon, but Prusa will always sell their stock first and then supply Printed Solid in the US later.

I don’t have the MMU for the CORE One, but the CORE One by itself is good. I haven’t had any issues so far aside from very flexible TPU (85A and softer) not loading or printing easily. I also have the buddycam and uploading models and printing and monitoring remotely is pretty easy.

Printables and Thingiverse typically. Sketchfab is great for 3D scans of real objects.

I recently traded up my Sovol SV06 for a Prusa CORE One and have MK4Ss and an SV07 Plus at work. The Sovols are good budget machines in general, but the SVO6 was so much more reliable than the SV07 Plus, which required a lot more troubleshooting. The MK4Ss and the CORE One are great if you have the budget to spend on them. They’re reliable and good quality. The community of users is large and any issues you might run into have typically been troubleshot by others already.

I’ve heard squeaking from an extruder that had little bits and shards of previous filament that was getting stuck during loading and unloading of filament rolls. You might try opening it up and seeing if there’s anything stuck in the channel or grinding against a gear.
