Estes is offering a $40 kit so you can print your own model rocket parts. Loved building models as a kid, might be fun to do again.

For those of you running your printers from a Linux PC, what slicer software works for you? I switched from Windows to Kubuntu about 6 weeks ago. Had been using Orca for about 2 years, but the Linux version doesn't fully function for me. The build plate preview and functions are just a blank page. Trying to link a 3d printer causes Orca to crash. From comments online, there are plenty of people with the same issue and no resolution yet, using various Linux distros. So is anyone having luck with a slicer program using Linux, Wayland, and a nvidia graphics card?

Update 07Aug25: so far seen that Orca does not work with the latest versions of Kubuntu (25.04) nor Ubuntu (25.04). That's trying both flatpack and app image. Installed Mint Cinnamon 22.1 (based off Ubuntu 24.04), and Orca partly runs from a flatpack install. The build plate image and features do show up rather than a blank page, which is a start. Unfortunately trying to link my printer by IP address causes the software to crash after I click on the Device tab. Now Orca won't reopen without immediately freezing up, then crashing after about 20 seconds. I think I read about a workaround on Discord for this, need to find that discussion. Downloaded Prusa, just need to try that as well when I can get back to this. Cura refuses to connect to my printer at all so far. It's been revamped to align with Ultimaker printers, changed a lot from when I used it a couple years ago. I don't think it likes my Klipper setup. May work if I went back to stock Creality firmware, but I have no desire to do that.

Update 09AUG25: Right now running the LTS version of Ubuntu (24.04.3) and Orca is usable. Installed using the flatpak. Like under Mint, I can get a visible buildplate and work with a model under the Prepare and Preview tabs. I entered the IP address for the printer under Hostname (using Octo/Klipper for Type since I'm on Klipper) and can upload files to the printer. So long as I don't touch the Device tab in Orca, it doesn't crash or lock up. Access the printer through the web interface, just put the printer IP address into Firefox and can run from there. So, I have something that works at the moment. Thanks everyone for suggestions, it helped point me toward something workable!

So, found out the hard way that you can't apply heat to neodymium magnets. Had 16 magnets to press into a print (tool holder). Thought since the soldering pen I use for inserting threaded nuts into prints works so well, I would use it for this too. And it did work well, but now all the magnets are not magnets any more. Yup, heat will demagnetize them. Part is useless, so had to trash it. Found out something new, but wish I had heard about this beforehand.

Don Hertzfeldt's final student film, BILLY'S BALLOON was shot on 16mm at UC Santa Barbara in 1998. It was nominated for the Short Film Palm D'Or at the Canne...

There's nothing fun about 4:30 in the morning.

I love that having a 3d printer means you can create custom parts when you need them. I wanted a set of leveling brackets for a router table insert. Sketched up something in Solid Edge, sent it to the printer and a few hours later I have what I need. Nothing complex but functional. Used PETG on this set.

Probably the one thing they didn't plan on going wrong.

Last album put out by the Unfit a couple years ago. Worth checking out.

I was looking at the settings for Connect, hit "Save Settings" before closing, and now some of my phone's default colors have changed. I have lime green and mint for random text in different applications. Using a Google Pixel 7 Pro. Anyone else notice this?
