But how do I lower the tension? I think its just the friction in the tube.

It comes with 2 spinning tubes so it does spin freely

Welcome to the world of 3d printing

I will be using PLA

But doesn’t that create an offset weight? My part will probably spin at several thousand RPM.

Some addition to my post: The computer I found is a Fujitsu Esprimo Q957. I’ve read online that they are very power efficient and don’t draw as much. I will probably run some lightweight task almost 24/7 and sometimes heavier tasks for short periods of time. A raspberry pi is for me too expensive for the average specs, even if it is very efficient. I think a upgradable pc or mini pc is best, because they are cheap, but can be easily upgraded without buying a whole new computer.

They are way cheaper than fairphones where I live.

I dont know. Its not that I dislike pixels, I just liked the concept of Fairphones. And I just never thought about google phones because I thought google and privacy don’t match, even if I have a different OS installed.

I do consider the missing headphone jack a problem, but are other brands better? I did not research any of this, but don‘t other brands do the same. Considering this, I think Fairphone is one of the better phone producers. Im not saying they are the best or that they do nothing wrong. And please correct me if I’m wrong, I think the high prices come from the higher loans and better quality materials than other brands.

What about de-googled android? Is that private/secure?

Can you explain that? Why is Fairphone problematic?

Yes thanks. I meant giro-card.

Every step you take towards a more private digital life is essential. I mean you have to start somewhere right? And the phone is in my opinion the biggest privacy thread out there. I am not on GrapheneOS but I’m considering switching soon.

No. It’s not as popular. In Germany most have a giro-card, but credit cards are becoming more popular. Many still prefer cash though.
