  • Ok, I’m going to step up to the plate here. I’m an experienced butt stuffer. There are two main safety concerns – having your body move things further in than you can retrieve, and unsafe materials giving you ass cancer.

    You’ve probably heard the adage, without a base, without a trace. In essence, your pelvic floor muscles will move objects around without you being aware or being able to stop it, and it can make things very difficult to retrieve. Your rectum is actually split into two by a muscle known as the inner band, which technically isn’t a sphincter but is in practicality. When we squeeze stuff out, we’re compressing the bottom half, squeezing the band and loosening the anus to push stuff out. If something untethered or without a base makes it’s way into the upper half, you’re not just going to be able to squeeze it out like when you shit, it’s in the wrong place for that. You’re in for an anxious fishing trip or wait, or a very embarrassing er trip. And this movement isn’t something that happens by accident, your rectum actively moves stuff back up if it’s not expelled.

    Second, material safety. In the US, it’s perfectly legal to sell toys that aren’t body safe. I don’t recommend plastic for anal use at all. Silicone is safe, but it has to be platinum cure or medical grade. These use platinum as part of the silicone curing process and is incredibly resistant to breaking down, which tin cure silicone will do. So, even a silicone egg with a tether might not be safe for butt use.

    Ultimately, I honestly don’t think vibrating butt toys are all that great. I highly recommend getting a “big” (large as you can fit) squishy plug like a square peg egg plug or a topped toys gape keeper and doing kegel exercises with it in. That’s been far better for prostate stimulation in my experience.







  • Random person who took a material science course in college here, polymers like polyethylene are constructed from their component monomers in chemical reactions. Not all monomers end up in a polymer chain, and some remain trapped in the material. These are what leeches out of the plastic over time. Better manufacturing processes have cut down a lot on this over time but it’s not something that can be eliminated entirely. These are also referred to as micro plastics sometimes, and sometimes not–it depends on the knowledge of the person speaking and whether or not it suits their point. Anyways, there’s your not so fun fact for the day.






  • Took a quick crack at doing it by hand, subdiving an icosphere in that specific way and copying it around.

    Definitely a bit time consuming but not too bad for that many faces. I imagine scaling it up would make finding an automated solution more important though. That was maybe 10 minutes of work? not bad

    scaling it and solidifying yields this

    Step by step:

    Basic icosphere

    Subdivided the edges and connected to opposing corners to find the middle of the triangle

    Cut the last edge in and dissolved unnecessary edges

    Repeated for each level, then duplicated and rotated 5 times to make the sphere out of these divided faces (mirrored on the z axis to save half the work)

    Selecting all those midpoints with a side on xray view

    From there just scaling them out to make the pyramids


  • Yeah I didn’t realize you were after a specific style of faceting until I posted the comment and scrolled back up. I’m sure there’s an easy way to do it in blender, I’m just not quite sure how… I’ll let you know if I figure it out! The method would be subdividing each face of the icosphere in three, with a point at the center of each triangle and cutting lines from the existing corners to it, I’m just not sure how to do it automatically. Once you have it divided like that, easy enough to grab those new center points and scale them out to make your triangle facets

    Here’s the result the deleted comment yields

    With a basic bevel


  • Whole lotta talk about filaments but none about modeling – in blender, create an ico sphere, then add a subdivision modifier. Then, add a decimate modifier, set that modifier to planar, and slide the angle limiter till you’re left with only hexagons (and a few pentagons). Apply the modifiers, then in edit mode, select all, then scale non z factors (hotkey s then hit shift z) to get it to lightbulb shape. You can add a solidify modifier to take it from a solid to a hollow sphere, then from there you you can do a boolean cut in edit mode or with a modifier to take off one of the ends. Personally I’d take it into fusion 360 from there to add your attachment method and/or base piece. Let me know if you have questions or want help!

    Aaaaaaaa the ole “I can’t stand this person because they’re a prime exhibition of the traits I really hate in myself and supress as hard as possible”. Unfortunate when someone accidentally activates my self hatred as regular hatred, they don’t deserve it
