Toothpick Dispenser

thingiverse

This is my first attempt at making a printable object. It is a version of the "sanitary toothpick dispensers" that you might see at restaurants. There's an old one floating around my house so I decided to copy it to get some practice with openscad. Since this is my first time, and I don't yet own a 3DP, I'm not sure this is actually printable. I'd appreciate any feedback on things I can correct to make either the design or the file itself more easily printed. Some of the concerns I have about it: The walls are 90mm high and only 1mm thick. I'm not sure what the guidelines are for structural stability. The sloped ramp inside the dispenser is not supported, so I'm not sure if it will print properly. I'm not sure how well the pieces will fit together after printing. Ideally, there should be stops so that the cylinder will only rotate about 100 degrees. It should work fine without them, but it will be possible to dump toothpicks into the bottom, unused section. Also, I'm not at all certain that it will work as designed. So there's that. If you have any suggestions please let me know. Thanks to mikeq for pointing out my error with the difference function. Instructions If you decide to print this, please either look over the OpenScad code first to make sure you're reasonably confident it has a chance at working, or let me know what you'd like changed and I will do so. Assembly should be simple. Insert the cylinder into the cabinet, and insert the knobs through the matching holes from the outside. If there is not enough friction to hold the knobs in place, I was planning to use a drop or two of glue. To operate, just rotate the cylinder so that the slot is inside, then out again to receive a toothpick.
