Good evenigng, is it a lot of effort to redesign the Euro coin Sorter to a Swiss coin sorter ?


I'm not the original designer, I've only fixed the orientations. You can find the original model here and who designed it, so you should contact them:


This looks so cool! Not sure my monoprice mini can fit it though (12cm^3). What is the size of the largest printable part?

I believe the tallest part is 14cm. There's one part that's really wide (the coin sorter with different sized holes), which is around 23cm. You could print it diagonally, but it's still 19x19cm. You could split it in two and then glue the pieces together.

but why is the scaling so different between the parts?
the gears in particular are different in scale than the rest of the body parts.

The scale is the same for every part, I've just double checked again.

Maybe your slicer is automatically changing the scale? If you'll share a photo of how it looks on your end, I might be able to help.

your right. i loaded them into a different software and the scale is fine.

Are the coin slot parts ("Bandeja" 1-2 and 2-2) really supposed to be printed upright? Seems like printing them flat down would make more sense?

If you print them in their current orientation, then you don't have to use any supports at all and the bottom will be nice and flat. You must use brim though (I think I've used 25 lines), otherwise the surface area is too small.

You could print them flat down, but I'm quite sure you'd need to use some supports then and you won't get a smooth flat bottom once you assemble them. I suppose you could use sandpaper in that case.


thanks for the rotating.

what tool would you recommend to change the Rampa_Selectora.dwg so i can use it with Danish coins?

we only have 6 coins and the smallest is 21.5mm and the largest 28.5mm

Anything that can edit STL files. Since it's not a complex model, my personal choice would be Fusion360, but I think you can do it just as easily in Tinkercad as well. This isn't my original design, but I guess that all you'd needed to do was create 6 circles with the correct sizes and then extrude them in the Rampa_Selectora model.

i asked the author of the design to consider making it parametric

i also found this one: https://www.thingiverse.com/thing:2195624

not as elegant but i think it will do the trick and its much less work to customize (hint hint... parametric fusion360 files)

Parametric Coin Sorter

Yeah, I think that one might work as well. I was about to print it before I found this one (which works great).

Good luck, I hope you get it working with Danish coins.

thanks for rotating..this makes things a lot easier. :)

can you do one for Brazilian`s coin size?

please, my email: andre.pcontato@gmail.com
