Tampão para o rabo (atualizado, V3)

Hmm, I'm not familiar with the Orca slicer. I also won't be home for a few days so I can't troubleshoot myself. The models are supposed to be airtight, so there shouldn't be issues with geometry. My guess it that Orca slicer might want the mesh to be triangulated, which my obj probably aren't. What you can try is opening the included blender file, selecting the model you like, and exporting it as stl (mark the checkbox to export selection only)

The issue is not solved, can you convert to 3mf instead of obj?

issue still exist cant print what has been uploaded

Importing into FreeCAD and exporting as stl worked for me. Might also work with Fusion360

Thanks for the suggestion, I updated the model : )

Most likely, no, but make sure whatever resin you're using is safe to be... inside.

Probably needed higher infill/wall settings. I ended up using 100% infill PETG, not sure what my wall settings are but it's solid.

sucks to be you

I highly recommend that you polish it and possibly top coat it with something that's smooth not harmful to the body. The place it's intended to is quite delicate, and the rough surface created by layer lines can at best irritate and at worst leave micro cuts.

You could potentially try acetone smoothing with ABS if you've tried it before, although it can weaken the filament, so for that I'd make sure the neck has enough material inside that it won't snap (4-6 walls with .4mm nozzle should be plenty). Otherwise you can use sandpaper, starting with large/medium grit and moving towards fine. Sandpaper sponges work really well on round objects like this. And in any case, do use plenty of lube. Good luck : )

I own a butt plug for home defense

You can use any sandpaper, starting with medium/fine grits, slowly moving to extra fine for a smooth surface. Although sandpaper is not the only option. If you print in ABS or ASA, you can use acetone for smoothing. It's much easier and achieves a mirror-like surface, but I'm not sure how safe it is, because some acetone may remain in the filament. I recommend looking up a video on how it's done.

As for infill/wall count, the main point of concern is the neck, which is the thinnest. You have to make sure that it's strong enough that it won't snap. For PLA, I think 1.5mm wall thickness and 15% infill should be enough. ABS/ASA may require more because they have worse layer adhesion. To improve layer adhesion, you can also increase the line width and/or print with thinner layers. For example, if you use a 0.4mm nozzle, you can set the line width to 0.5mm. This will make the print stronger, as well as save you some time.

Sure! Go ahead, I don't mind. On a side note though, I figured that the neck of the plug is a little too long. It might be worth shortening it a little.

Base on the build plate. Can be printed without supports if your printer has good enough print area cooling.
