A screenshot of a social media post from the account "GET A GRIP" (@docrussjackson
), timestamped 1 day ago, with a blue checkmark. The post quotes a previous post by "Martha Kelly" (@MarthaKelly3
), which reads: "Under capitalism, it’s normal to let children go hungry, let banks force people out of their homes, let sick people die for lack of access to healthcare. But the idea that billionaires could just be less rich – not poor, not struggling, just less rich, is considered insane." The quoted post is followed by a reply from "techsiren" (@techhsiren

Just less rich. That’s all we’re asking.

100% failure. :-(
Until the tree support starts to support the star, the two bottom star spikes are standing on very small footprint. :-(
If your slicer supports it, you could try manual support on the inside of the two star spikes.

Three Piece 3D Puzzle by Hari Wiguna | Download free STL model | Printables.com I learned about this puzzle from Matthias Wandel, but I recreated this in Fusion myself. | Download free 3D printable STL models

I saw Matthias Wandel's wooden puzzle this weekend. I
paused the video and modeled the three pieces in #fusion360.
If you like puzzles and have access to a 3D printer,
Give this a try. It is much harder than it looks!

Ah. I don't know how robust ESPNow's wireless connection is, but since ESPNow lets the ESP32s directly talk to each other, that means you're no longer dependent on the WiFi access point at the venue.

Congrats! If you ever need to send data between two (or more) ESP32s, check out ESPNow. I can't believe how simple it is to use.

I bought a Sovol SV07 a few months ago for $250 and have been happy with that purchase.
It is NOT a slick upscale appliance like a Bambulab printer. It uses plastic rollers and requires manual paper Z-Offset, but it is a decent Klipper based printer and for $100 I'm willing to give it some slack. :D

Ouch... I'm familiar with 3D printer parts, but not specifically the Bambulab. What part is that? Do you know what happened?

I bought my Hakko soldering iron so long ago that I cannot remember when. It's the one with analog dial. PS: I'm posting this on a 2013 Macbook. I wonder who has the oldest still being used Mac/PC?

I took Math 1 in college and discovered that it was actually intro to BASIC. We shared a PDP/11 using various terminals.

The first personal computer I had access to was an Apple ][.
