    I modeled a one piece snap lock box and printed it in Sainsmart TPU filament ( Glow in the Dark ). I used the cross support "everywhere" and cleaned up the finished model as best as possible. Probably need to raise the support percentage.

    Hollow inside. Note the hinge.

    Lid semi-closed. Note the hinge at the upper right.

    Lid snapped shut.

    It was printed in one session and then cleaned up using a thin spatula and needle nose pliers.

    Nice idea. The TPU will make that totally work although you could do something similar with others (but the hinge would wear out faster).

    I agree. The model ( printed using TPU ) has semi-rigid walls and a flexible hinge. Hardest part is separating the lid from the main box without damaging the hinge. The thin spatula really helps.
    And the lid snaps on tight.

    I'm tweaking the print profile for the overall best print. Given the nature of this model, I would not recommend printing with NinjaFlex filament.

    I bet nylon would be a winner for this. One of the more flexible blends (but not as flexible as TPU) pretty much any would likely work well although I'd try Taulman 230 -- bet that would cover the bases. Flexible enough to bend well and tough enough to stand it for a lot of cycles.

    Should even print on a C2 -- I need to try that at some point :)

    I have attached the STL file ( zipped up for speedy download ). The model is suitable for a small gift wrappable container.

    Some printing parameters:

    Print quality - Medium
    Support percentage = 15 to 20%
    Support - everywhere
    Support Pattern - cross
    Z top and bottom support gap - around 0.2 to 0.3 mm, but not smaller than 0.1 mm
    X-Y support distance 0.7 - 0.8 mm
    Cooling - 100%
    Shells - 4
    Infill Percentage - 15 to 20%
    Infill Pattern - Triangle

    Material - any suitable flexible filament but not NinjaFlex ( too flexible )
