04:14 <J22> abff happy i could help -  if you render with F6 save as 3mf (the better stl)  you can use this on  any slicer (converted into gcode)  to get printed

04:18 <J22> keep in mind to have enough clearance  so a 20mm coin needs a 21mm hole to move easy

05:33 <InPhase> abff: For printability you're probably going to want to modify that to remove the overhang part of the triangle (can't print over open space) and instead bring the back side of the triangle in more, so you get a larger stop gap but with all bridging instead of overhang.

05:34 <InPhase> That would enable you to print without supports, which is always convenient. Alternatively, you can just print with supports and clean it up. But it's nice to not have to do that when you can instead tweak the shape a bit.

05:58 <J22> InPhase still awake? ..   not sure it is that simple even cutting the overhang fully doesn't ensure that slicer bridge that proper

06:07 <J22> a nice feature would be also a slight notch so coins only slide out if they are pressed down a little

06:14 <InPhase> J22: I pictured a triangular shape, just angled differently so that it would be a natural bridge, which the slicer couldn't miss.

06:17 <InPhase> Although an edge notch would indeed be a nice feature. One way to do printable with an edge notch in a coin dispenser, would be to flip it the other way around and put the dispensery on the bottom of the print, and then close the gap with an arch. Call it a feature to see how many coins are left, and nobody will notice that you did it just to make the print work. Any bridging issues in the fully

06:17 <InPhase> closed top cap would be minor, cosmetically hidden, and just slightly affect capacity.

06:39 <J22> slicer often only bridge proper between parallel walls ..  there was one guy developing a script for superior bridging  but didn't got into cura - not sure why

06:45 <J22> a slight angle  (10-20°) of print orientation could also help

06:49 <J22> another trick is to stop the print .. put coins in and let it print on the coin..    A upside down printer could also use a support shield to stabilize midair prints

06:50 <J22> some very stiff material (CFfilled) can nearly print in mid air

09:22 <J22> https://www.printables.com/model/210810-hilbert-soap-tray   why is someone stating "made with openSCAD" but not uploading the scad

10:53 <abff> J22: InPhase this is all great advice. I'm probably going to end up sanding the whole thing to soften the edged of the hexagonal prism, so a but of extra cleanup is not going to scare me.

10:55 <J22> abff  use  minkowski (){cylinder (50,d=30,$fn=6),sphere(1,$fs=.4);}

10:56 <J22> and save time sanding

10:57 <J22> minkowski (){cylinder (50,d=30,$fn=6);sphere(1,$fs=.25);}

11:00 <abff> J22: Noted

13:14 <J22> soap dish anyone? https://www.printables.com/model/211230-disphenoid-seifenschale

15:03 <teepee> looks dangerous. but I'm lazy, I use liquid soap

15:05 <J22> i am using foam https://www.printables.com/model/154914-foam-nozzle

17:58 <InPhase> J22: Well that looks like a nightmare to clean the soap scum off of. :)

17:59 <J22> never heard about ultrasonic bath and  pressure washer .. soap is water soluble Ü  ..  but sure i will not print that

18:00 <InPhase> Although I guess you could just print another one when it gets too dirty!

18:00 <J22> when i made the structure the first time it was intended as anti-splash  surface

18:00 <InPhase> And yeah, ironic that soap, the thing you clean with, would need to be cleaned, but there always seems to be some sort of residue build-up when all the soluble stuff gets selectively washed away.

18:01 <J22> yeah todays soap is a mix of plastic  ..  also a reason why those refill foam soap dispenser clog

18:03 <J22> further hand / skin soap contain Lipides  (fat)

18:03 <InPhase> I make it a point to buy only authentic traditional-style bar soaps, so it's a whole lot better. But there's still always a little bit of sticky residue over time.

18:03 <J22> originally soap is made from fat

18:04 <InPhase> I use a ceramic soap dish though so it's pretty easy to clean.

18:05 <J22> i have a bowl sink  .. so there is nothing to put  on or to clean  Ü

18:05 <InPhase> I had become convinced bar soaps didn't work well until I discovered it was just because they weren't making most of the bar soaps right. The old style actually work better than most of the liquid soaps for bathing.

18:05 <InPhase> So there is merit in designing soap dishes. :) I just like them cleanable.

18:07 <J22> i had a bar soap where i cut an edge into so it stay on the rim of my sink bowl

18:09 <J22> basically soap is oil and drain cleaner (NaOH)

18:10 <J22> InPhase have a look at these https://www.printables.com/contest/71-soap-dishes

18:23 <InPhase> Chemically the NaOH is no longer in the soap. This is a transforming agent added to saponify the oil, and is used up in the production of it.

18:23 <InPhase> There are some decent options there among that soap dish contest.

18:25 <InPhase> There's no one true design, because it really depends on where you put the soap. For a fixed shower dish, a free-draining model is best, whereas a good sink model depends on the shape and spacing of the sink as to whether you want it to drain into the sink, or have a water collector.

18:26 <InPhase> And if you live in a dorm or something, you need one with a lid. :) I remember that life.

18:29 <J22> just a ring might be fine ..  i remember  in my childhood we had soap were you press a metal  cap on and use a magnet to hold the soap

18:34 <J22> haha or you just  screw the soap to the wall https://bilder3.eazyauction.de/LaMaisonHenri/auktionsbilder/5292_1_0d75481f.jpg

18:37 <InPhase> :)

18:49 <Scopeuk> Ahh rigid mounted "soap on a rope"

18:51 <InPhase> Soap on a stick is a new one. Probably not a great idea though. :)

19:12 <J22> looks like some "don't steal my soap" thing

19:15 <J22> btw. i think the version without the tray https://pasteboard.co/NcrScA2AsjSl.png  is  easy to clean

19:45 <gbruno> [github] skeptonomicon opened issue #4263 (color entanglement on non-intersecting object) https://github.com/openscad/openscad/issues/4263

19:54 <gbruno> [github] t-paul closed issue #4263 (color entanglement on non-intersecting object) https://github.com/openscad/openscad/issues/4263

20:20 <J22> hmm  what would happen if objects with less than 100 faces are "auto rendered "  in preview ?

20:22 <J22> ok probably confusing if cubes are rendered but  smooth cylinders are not

20:23 <teepee> hm?

20:42 <abff> InPhase: rag on a stick is much more effective

21:12 <J22> rag on a stick  pah  https://www.youtube.com/watch?v=gk0Gp6pTl68

21:12 <othx> J22 linked to YouTube video "Swiss cow getting a massage!" => 1 IRC mentions

21:19 <abff> I'd 3d print me one of those

21:37 <Guest83> oh my god

21:37 <Guest83> asdfsdfasd

21:38 <teepee> hmm, someone got scared :)

21:38 <teepee> J22: what did you mean with the "auto render"?

21:39 <teepee> like for simple designs no need for F5?

21:39 <J22> no that geometry is rendered in preview  so   a cube(5)  is always  a  render()cube(5);

21:40 <J22> just a thought to minimize  z fighting

21:41 <teepee> hmm, I suppose right now it partially depends on the internal data structure, so it's a bit random from user perspective

21:42 <J22> yeah  people who know will not need it and others get even more confused

21:42 <teepee> it might be possible to maybe add some flags to the render tree, but I don't know that part of the code very well

21:43 <J22> i understand the ticket that  it is  inconvenient  that  invisible geometry is intersecting and creating flicker

21:44 <teepee> yes, certainly

21:44 <J22> so if  a scene  render in less than 1second .. it could  always render  (but with colors)

21:47 <J22> would probably also allow colors in WASM  in the longterm

21:49 <teepee> yep, I think part of the stuff from the fast-csg branch goes in the direction of tracking what happens in CSG operations

21:50 <teepee> I'm not sure, but it seems it may even provide the places where things intersect, for potential stuff like auto-fillet

21:50 <teepee> we'd need more people who have time for that stuff :)

21:50 <teepee> I wish I had more time to really follow that code
