I don't have a source, some looking will find it, but NASA used to have to be in the public domain. Now they partner, and the partner gets the patents. I know the Apollo soyez mating hardware was public domain, and apas docking is still.

I also seem to remember that research paid for by the USA, used to have to stay public.

I don't have a source to quote, just memory.

There really is no good reason for not being open source.

My claim was I didn't know of any others. I've seen rat rig and voron. I'm not sure if they are really open source. I tried to contact them last year, but the documentation was locked. I'll favorite your list flow when I get some time. I'd love to build something like my first reprap.

Other than prusa, I'm not sure of any you can purchase. Of the build yourself ones, they are variants of prusa. Or corexy. For a bedslinger, I built a bear upgraded prusa Mk something. But custom, so not exactly. For my next, it will be a variation of a corexy. Smash together a voron and the other popular one. Because I don't like the bed design.

My wife wanted tulips. So we bought a dozen and planted them in a row next to the driveway. As they came up the bunnies and squirrels ate them. My wife was sad. So my wife said, if they eat a dozen, they won't be able to eat a hundred before they bloom. So we planted a hundred. After several years, we still have a couple, but we need to plant more. The critters will eat what they like. If I wanted something, I'd plant more than 3. In all seriousness, I hope it survives and thrives, I have a few, and the critters and insects like them.

I find that squirrels have a lot more time in a day to try to figure out how to get to food, than I have to try to prevent them.

If I stop the squirrels, its more interesting to the bunnies, so then they join in to try.

If the bunnies try, then it becomes a competition with the chipmunks and ground hogs.

Within a week I have a deer in my yard claiming victory over all the tiny animals that aren't as great and majestic, while standing over the hole that used to be my special plant.

I'd try raising the temp on the heat bed and maybe on the extrusion for the first layer.

The bed arcs up in the middle when it heats, so it may also be an issue with z offset. If it is 0.35 in the middle, but 0.45 at the edge, you might just need to smoosh the first layer more. Speed also effects first layer, so slowing down sometimes helps.

Find a big flat one layer test print and see what helps. Just don't doal bunch of changes at once.

Depression is so very hard. Its unbelievably hard. I spent most of my life depressed. 13 to 50. Not being depressed is weird. I don't know who to live without it. I tried drugs, they made it worse. Suicidal tendencies made it hard to take drugs. My first break was laughing at a kids movie, it was a real laugh. I broke down and cried. It was the beginning of getting rid of depression. Maybe 10 years before I was out of it. Things slowly changed. Lines like, "it is what it is," helped. I work on mindfulness. I avoid thinking about anything that has negative emotions. Really, I avoid thinking. Mostly, you need to change the way you think and behave. I am not the person I was. I act and do things differently. Be willing to change anything to get out of it. Fear of change kept me in it for a long time. Good luck. You are not alone. You might be able to become a survivor. Keep trying.

I agree. I'm just tired of the concept of profanity. It makes no sense to have words that can be used sometimes and not other times. Like don't swear near a lady, or children. Use the word that means what you want to convey. Someday, it will cease to exist.

Picquic multi screwdrivers.

I think it's more of a bell curve. Your ability is somewhere on the up curve. If you practice, it will get higher. I practiced when I was younger. I am a poor shot. I tried later, I'm worse. I am neither eye dominant, so sometimes I hit, sometimes I don't.

Try it. Maybe your good, maybe not. Practice can help you improve, but only if you change.

Used cast iron pans - last lifetimes and can be used for so much. French press - coffee, tea, chicory, herbs, mushrooms ...

Honestly, I can't think of much stuff at a higher piece point that isn't specialized. Useful things tend to be relatively lower cost.

I carried a leatherman for years, but rarely used it. I find an adjustable wrench, picquick, pliers and box cutter more efficient and easier to use.

Although, I really want cool stuff.

I can't think of a clearer or more concise answer.
