Very nice, smooth and sleek design. I printed it three times with different layer heights - one with designer preset 0.2mm, then 0.16mm and 0.12mm. Could prove my assumption, the smaller the layer height, the smoother the two parts are sliding. In my last attempt the two parts are are really flowing through each other. There is a drawback of printing thinner layers, the overhangs on the spiral part are not perfectly clean. Reducing printing speed would probably help here.

Great model, works very well

Great model. Printed in silver silk PLA.

Perfectly usable result

The final result is nice. Removal of the supports filling the notch of the lid are the only nuisance, as you will need to cut them out. But yeah, in the end you will come out with a very nice box measuring ~8,5x4,7x3,8 cm

A nice small box 5x3x2 centimeters. Hinge and closing mechanism work well.

Printed very clearly. I used silver style PLA.
