Parameterized snuff box (snusdosa)

thingiverse

A snuff box should be straightforward to open with one hand, yet remain closed when it needs to. Commercial boxes achieve this by injection-molding thin walls with a flexible plastic that enables the entire box to flex and locks the lid with tiny flanges. I couldn't determine how to print something like that with reliable results, so this box is rigid. The lid seals with a gasket. This isn't a Thingiverse customizer because it utilizes external DXF files, which aren't supported. However, the latest version of OpenSCAD (2019.05) has a built-in customizer: uncheck View->Hide Customizer and experiment with the parameters. The scad file attempts to correct for invalid inputs, but it's still possible to produce something unprintable with it. Also included are parts to make a silicone mold around the box. They can be used to cast a box in resin or some other castable material. ### Printed parts #### box_bot.stl, box_bot_wide.stl Bottom part of the box. The box_bot.stl is easier for making a mold, but box_bot_wide.stl provides a little more storage space. Layer height: 0.1 or 0.2 mm. #### box_top_X.stl Top part of the box, plain or with lid design. Layer height: 0.1 or 0.2 mm. #### inlay_X.stl Print one of these if you want to inlay a logo with a different color into the lid cutout. Depending on how your printer handles bridging, you may need to scale it down along Z. #### gasket_X.stl Layer height: 0.1 mm, 100% infill. This part should be printed in a flexible material. It will probably require some trial and error to get right, depending on the material. Luckily, it's a quick print. If you don't have any flexible filament, try a rubber band or an o-ring. #### shell_bot.stl, shell_top.stl Print these to make a silicone mold around the box parts. Use spiral vase mode, 0.3 mm (or whatever is fastest but still leak-proof).
