I design my own stuff, and I’m super critical of designs. while ideas are often good, execution tends to be lacking. Not here. The 3mf is fantastic. The designer has ensured that all parts have proper strength, while also using minimal filament. its truly impressive. moreover, the models look professional and features are clever. Super well done. I will be printing shelves for weeks, but I’m excited to finally have my messy storage organized. Thanks for publishing this model.

Excellent simple design, printed well too. The slotting is tight, but works well with PLA. Thanks!

Not bad, but there are some issues. I only printed the insert for now (the grey piece in the pictures from @RDLP ). The design hasn't been filleted anywhere, which means it has sharp edges everywhere. The slots for the wedge shaped pieces are just triangular, which does work, but I would've preferred slots that follow the contours of the pieces that go in it. I also find it really hard to insert and remove the circular and wedge shaped tokens (I admittedly have fat fingers). The slot for the 1-2-3" measuring tool is also much too large (you can see this in the picture from @lpw1986 ). Finally, the finger hole in the center is narrowing back up towards the side where you need to pick up the pieces, but it is still usable. From the above, you may think I don't like this design, but that's not true. The layout is well thought out, but it all just needs a little polish. I have no opinion on the lid or box, as I have not printed them, but they look nice and functional.
