This is a handy container to hold 25 marbles and stack in groups of 25 with a lid for the final tray. It is designed to fit 16mm or smaller marbles.
This is basically a remix of https://www.thingiverse.com/thing:2941162 (Parametric Stackable Sieve) which was in itself a remix of https://www.thingiverse.com/thing:754365.
I liked the lip and the stackable idea. I took the bottom section off and modified it and changed my top a bit.
The Bottom has little Nubs to hold the marbles from banging into each other if you use smaller marbles. My marbles were about 16mm. I think the standard marble is 8mm.
I see this good for storage / transportation of marbles and marble collections in schools and maker spaces. So next time you take your marbles to an event, you can carry them in style.
If you are a marble collector and find this useful, please drop me a note. I'm curious how people organize marble collections or if everyone just keeps them in a jar like I used to do. :)
I added an extra lid that has bigger finger holes and a low profile "handle" at the top. You might find this extra option a better choice for lids.
I did an infill of 15% and it was good. I'd assume if you get tooo low then you might get gaps in the final top layers depending on your slicer. As is evident in the test piece in the picture.. The prints on the left are at 15% and the right is 10% infill.
