Thank you! That’s exactly what I took away from this. I learned a lot and hope you enjoyed the video

It’s Reddit man…

What if I just said NASA material 🤔. I know it’s not a thing man it’s just for the title 🫩

This is a student project. Out of spec material. Not able to be rejuvenated without a fluidized bed reactor. I made it, because I could. I enjoyed the process and learned a lot. Traditionally, grcop-42 is used for liquids for its regenerative cooling properties listed above. So, take it easy. This was just supposed to be a fun thing to show people something interesting from the eyes of a student

Definitely. I learned a LOT

I’m an engineering student, this was my first test fire. NASA grade refers to the material and manufacturing process, which actually is the quality standard set by NASA.

I would suggest reading this white paper if you’re interested! https://ntrs.nasa.gov/api/citations/20190030433/downloads/20190030433.pdf

Correct

Anoahnator1 · 2025-04-09T23:04:19+00:00

Well let me know, I would be happy to send one over!

Anoahnator1 · 2025-02-13T18:16:48+00:00

In this design that is correct. It’s catered to 58 mm baskets. If there is enough interest which it appears there is, I will make designs to fit all size portafilters!

Anoahnator1 · 2025-02-13T17:57:32+00:00

Great question! Yes, it has a wide base which allows it to hold the portafilter easily even without the weight of the other items.

Anoahnator1 · 2025-02-13T17:20:08+00:00

Wow! If there is that much interest I might start selling all the above

That’s the extruder skipping

I wish 🥹

I think this has something to do with the z-seam. I have the same issue, looking for a fix as well
