  • The edits are really very simple, you’d just have to chop the model into a few pieces. I think windows has a built in tool that can do it. Actually I think it’s possible to print it without edits, by standing it upside-down on the flat bit at the top. However since the contact area is so small, and the print is so tall, it would be more likely to fail. I wouldn’t try it on my machine, but since you’re going through a print farm I don’t think that would be an issue, there’s no way they’d send you a failed print so they’d probably just print it again. You might get charged extra if they have to redo it? I don’t know how these companies work you’d have to ask them.

    If you don’t want the glowing then I think there aren’t really any issues with printing that, as I’ve said some minor edits would make it easier to print, but it would definitely be sturdy enough.


  • I’m not a pro at 3D printing or painting, but I think I know enough to answer your questions.

    Ok, so first thing out of the way- that model you linked is not made for 3D printing. To get a decent result you’re gonna have to edit it a bit.

    This is intended to be a hand-held prop, not just a display model. So my first question is, is that even feasible? I don’t know how strong things like this are. I’m not going to be hitting anything with it, but a little bit of waving around I think would be in order.

    Definitely feasible. There’s a wide range of durability with 3D printed stuff, but you’d have to go out of your way to make something that can’t handle that.

    Assuming that’s ok, what material should I use? Not entirely sure I even get a choice but I think so?

    PLA is the default, and it would work ok, you could also switch to PETG. PLA softens at a very low temperature- roughly 60°C. It’s not too big of a concern, but there’s a small chance of it deforming if, for example, you left it in a very hot car, or under a window that happens to focus the sunlight on it. For a prop like that you don’t have to get more fancy than that. You almost certainly get to choose- I don’t use these 3D printing services but I’d actually be slightly concerned if they didn’t.

    Another question I have is about painting. I’ve seen painting guides online, but one question I have I didn’t find an answer to is again, about it being hand-held. I don’t want to use a paint that will come off or smudge with sweaty palms. Are any kinds better for that than others? Are any?

    Even just regular craft-store acrylic should hold up decently well, but you should use a sealant/clearcoat/varnish. I don’t do this so I can’t help you much with that, but it should be as simple as just spraying the whole thing with it after you’re done painting.

    And how close could I likely make it look like in the link? It doesn’t have to be exact, but there’s metallic parts, glassy parts, kinda gives a glowy impression… or is this going to be too hard for someone with no experience? (I’ve painted a couple of model kits when I was a kid.)

    Probably not very close. The metallic parts are ok, there’s paints that mimic metal, they’re not going to look fully convincing but it’ll probably be fine. You can get glossy clearcoats too. The big issue is the glowing part. There are ways to make something look like it’s glowing by using gradients and stuff (look up OSL painting) but I don’t think that works very well at such a large scale, and it’s difficult. For something this big I think the only way to get a good effect is to make it actually glow, which is a whole 'nother can of worms. To make that part look good, you’re going to have to do a ton of work. I haven’t done anything like this before, but I’ve got some ideas for how it could be done.

    Do you want to make a lightsaber, or specifically this lightsaber? If you aren’t particularly attached to this one I’d suggest looking for another model. Printables, Thingiverse, and Thangs have 3D models specifically designed for printing.





  • This is something I’ve been putting off. My world is post-apocalyptic. Originally, it was set so long after the apocalypse that the languages had changed to something completely different, but I’ve sinced changed it to <1000 years after the apocalypse, so I now have to come up with variations of modern names that are still somewhat recognisable but changed in some way.

    I have no idea how to go about this, so I just… haven’t named any of the people in my world. I really should get around to this.




  • Good point, I didn’t think about the smoke at all. I don’t think dwarves generally have innate breathing protection, so that would be an issue.

    I feel like I should clarify that this isn’t part of a project of mine, I just had this idea for a generic fantasy world (I guess maybe something Forgotten Realms/ D&D esque) and wanted to put it out there, so I’ve got no other lore surrounding it about dwarven structures or breathing or darkvision, etc.

    That said, I feel like dwarven structures are usually very well lit, so they wouldn’t be fighting in dim light much. And I think darkvision seems to be unaffected by bright flashes and stuff- they don’t seem to be negatively affected by fireballs or whatnot.




  • I’ve got two answers for this, one for before the apocalypse happened, and one for after.

    Before the apocalypse, it’s easy enough. I wanted the tech of that era to be near-magical, so that after the apocalypse it’s seen as magical.

    1- There’s already a bunch of mall santas (that profession is still around in the 2100s), just hire one.

    2- Get a large sack, buy a bunch of toys off A3 (Amazon-Alphabet-Apple), done.

    3- You’d have several choices for this. If you’re on a low-gravity world, you can hide propellers or thrusters inside the sleigh and it’ll probably be enough to fly. On Earth though, you’ll either need to basically build it as a massive 4-rotor drone, carry it with a helicopter, or use anti-grav tech. I’m leaning towards the former, since I haven’t decided yet how I want the pre-apocalypse anti-grav tech to be like. That’s the flying done, the sleigh shape is just building a decorative frame.

    4- Humanity’s gene-editing tech isn’t good enough to make flying reindeer, so they’ll have to be regular reindeer strapped to a rig in front of the sleigh. It might be hard to make that look convincing.

    5- Humanity’s gene-editing tech is good enough however, to make a reindeer with a florescent nose.

    As for difficulty, the hardest part here would be getting permission to modify a reindeer to have a glowing nose. The rest is doable for a small dedicated group.

    If they actually try to break into houses though, they’ll just get arrested. That is if they don’t get shot down first for refusing to identify themselves (“Santa” is not a valid identification number) and going into controlled airspace.

    After the apocalypse, it becomes significantly more difficult, for obvious reasons. Note, the post-apocalyptic part takes place on a far-off moon called Eren B, with about 1/3rd Earth gravity and few Earth animals.

    1- Finding someone fat might be difficult, as the low gravity kinda stretches everyone out vertically, but it’s definitely doable. The beard and red clothes is easy.

    2- Easy, sacks are everywhere. Obtaining that many toys would be expensive but that’s nothing compared to the next few points.

    3- Oh boy, this would be almost impossible. You can “fly” using a Shard Of Gravitation, but the problem is that you only have control over how strong it is, which is why they are primarily used to lighten vehicles instead of fully lifting them off the ground- if you lift off, you have 0 control. There have been experiments with people strapping 5 or 9 Shards to a single platform, with them arranged around the sides, so by changing their strength you can stay upright, but that is insanely expensive- even a single shard is worth more than some villages. And it still only lets you hover, not control your movement. Perhaps, if you manage to find an undamaged fully functional ancient sky-ship (an artefact that would quite possibly be the most valuable thing on the planet), and built a wooden frame around it, you could get a flying sleigh. I suppose another way would be to invent airships. Eren B’s low gravity make them a lot easier to build, but that would still require a bunch of technology that just isn’t available to them.

    4- Impossible again. Reindeer don’t exist on Eren B. The original terraforming effort didn’t move over the entirety of Earth’s ecological diversity, as that would have been pointless. Reindeer were left behind, together with most of the substitutes you could use. The closest you could get would be to strap horns to a horse, but that’s still difficult, as there are very few horses on Eren B and the ones that are around are carefully guarded by a (currently unnamed) group in the south, because of the large advantage it gives them. It’s not entirely impossible to get a couple from them though, either through trade or by stealing them.

    5- I guess you could strap a lantern to a horse’s nose? You’re already strapping horns to them.

    This would be impossibly difficult. No.3 especially is the issue, even if the entire planet was dedicated towards this goal that would still probably be impossible.
