Tissuebox with sine wave pattern

My family consume lots of tissue paper since my husband has serious rhinitis. Tissue boxes are important to me. I love forms of pure geometric shape and a box with customizable everything, including the decorative parts.

This one is created based on the sine wave, nice to print as a whole without the bottom lip part. I chose mortise and tenon (Sun-mao) as the structure for joint, got troubles figuring out the space in between. Finally, 0.3mm is tight enough to hold them together even when I drag the tissue hardly. For reference, I printed with a 0.4mm nozzle. If you want to change the connector, look up the Ultimate_Box_Generator at https://www.thingiverse.com/thing:2594893, which provides several options. A slider connector seems more durable.
