Ukulele Humidifier

thingiverse

Nothing is worse than finding a crack in your Ukulele because the wood has dried out. Prevent this tragedy by making a Humidifier for your instruments! Slips between the center two strings and snaps into place. Keep your instrument humidified while in its case. Designed not to drip! This may possibly work on acoustic guitars as well. Print Settings Printer Brand: MakerBot Printer: MakerBot Replicator 2 Rafts: No Supports: No Resolution: Standard (.2mm layer height) Infill: 10% infill Post-Printing Additional materials: Wet type Floral foam 1 Tyvek priority mail envelope A pair of scissors A sharp knife or a razor blade Assembly: Print all 3 parts. Cut two pieces of Tyvek from the envelope: one to fit in the inside of the lid, the other to fit down the interior of the box along the side with the two circular holes. This is to create a moisture barrier that allows water vapor to escape the box, but keeps water from dripping. Using the knife or razor blade, cut a piece of floral foam to fit the interior of the box. Insert foam into the box, being sure the Tyvek is sandwiched between the holes on the side of the box and the foam. Using scissors, trim one column and one row of squares from the Dryseal screen part, so it fits on top of the foam, centered between the walls of the box. The cap and Tyvek should snap over this on top of the box. Both the lid and this screen should be removed prior to filling the unit. Filling and use: Remove the lid and the screen from the top of the unit. Place the unit in a coffee cup, and pour in distilled water, and let the box sit for a minute or two. Remove the box, replace the screen, and snap the cap on the box. Shake off any loose moisture on the outside of the unit and pat dry with a towel. Insert the box, cap first, between the center two strings and into the sound hole, with the two circular holes on the side of the box facing towards the headstock. Push it in past the two detents near the bottom, locking it in place. If you are confused, please watch the accompanying video here: https://youtu.be/asUZs18bSWQ The instrument should be fine for 5 days to a week. Check the foam every 4 days or so to make sure it's still damp, and rehydrate the foam when it's dry. For best results, keep the instrument in its bag or case.
