Whats a hobby/craft that you wouldn't expect that has an incredibly high ceiling either monetarily or in sheer skill?
For example, I'm sure the average joe doesn't know just how expensive calligraphy pens can be, or how deep the rabbit hole goes on video game speedruns.
It's expensive, but it's also expensive in lots of different avenues. It's not like you can just go "well I'll never buy a big pre-built proprietary printer then I'll just make it myself! Open source forever!" Because that's the road to leads to sourcing and building your own voron from scratch and spending a thousand dollars on parts
I've been amazed at how cheap it's become since I built my first few printers. I spent thousands building printers that aren't half as good as a $300 printer today.
I can highly recommend the Klipper firmware if you haven't already, I can print at much higher speeds than marlin firmware and the print quality is actually better
I just bought an elegoo neptune 4 pro and thought about buying more filament already. Hopefully it will only be filament and not more machines or something
3D printing really isn't expensive, especially since you can create a lot of stuff for cents. I'm considering a new extruder for my Ender 3 (Looking at the LDO orbiter v2) and that's €70, which sounds expensive for the printer, but compared to any other hobby that's peanuts
Yeah, €70 is not much for an upgrade for a hobby. That's the price of a mid-range chain for a mountain bike and chains are not upgrades, they're consumables, which you buy at least once a year, lol.
