  • Speaking as someone who spends a lot of time poking around the RimWorld codebase, it’s mostly because the game’s UI tends to round things to pretty then up for the player. Under the hood, infections are usually some ugly decimal number (like .9956424) that visually round up, it isn’t until that number is fully at/ about 1 that the death by infection mechanism is triggered.


  • Chiming in to say that you absolutely don’t want that in your bedroom. Not sure how ubiquitous the experience is, but if you’re ever done a titration experiment in a chemistry class (the one where you add one solution into another a couple drops at a time), your body’s response to being exposed to resin fumes (as well as VOC’s from some of the more exotic fdm materials like ASA) is a lot like that: little by little you add more of one solution to the other and at first you don’t really notice anything (beyond the volume increase), so you keep on adding more, when you finally hit the equilibrium point the whole solution suddenly changes colors.

    In practical terms, the more you’re exposed to resin VOC’s the more you’ll burn through your buffer, once it’s gone your body will basically go into panic mode whenever it comes into contact with said material. It’s one of those things that’s high enough on the fuck around side of things that you really don’t want to find out…

    That said, welcome to 3D printing! There’s plenty of resources around, so (for the most part) if you aren’t sure about something or run into trouble, all you have to do is ask!




  • Kinda depends, if it’s a popular something, there’s usually a model online that someone else has been kind enough to share (generally on Printables and/ or Thingiverse). My most recent experience with that was the shift knob on my mixer cracked and fell off, a quick download, a few grams of filament, 20 minutes, a few persuading taps with a mallet, and everything was good to go.

    Beyond that, it’s a bit of personal preference and a bit of you’re trying to do, something like a dial cluster in a car is going to be far more complex that something like a mounting bracket. The stuff I tend to fix/ replace tends to be fairly small, so personally, it’s a matter of sitting down with a pair of calipers to measure the object and replicate it in CAD (Autodesk got me young, so I’m on the Fusion 360 train at the moment). One of the most amazing things about 3d printers is that you can go from design to prototype extremely rapidly, which allows you to iterate the design and make it better each pass. Got a hole doesn’t quite line up, a wall that’s too long, an arm that doesn’t quite reach, etc? tweak it and try again. It’s a little bit of trial and error, but with experience it becomes more of a controlled process as you figure out what works and what doesn’t.
