Scuba Rattle

thingiverse

This is a handheld underwater signaling device designed to facilitate communication during scuba diving excursions. To activate the noisemaker, simply initiate printing and wait for approximately an inch of material to accumulate before carefully dropping two 1/4-20 nuts into the mold. Any substantial object capable of generating vibrations will suffice; however, I happened to have these nuts readily available in my basement. The integrated loop on top is meant to be securely attached to a small carabiner or a keychain for added convenience. Alternatively, you can tie a length of cord and attach it to any safe location. Print Settings: Printer Brand: Ultimaker Printer Model: Ultimaker 2 Rafts: No Supports: No Resolution: 0.2 mm Infill Percentage: 100% Notes: To ensure optimal printing results, I recommend orienting the noisemaker vertically, with it standing upright on its end. The design's arch should provide sufficient support for this configuration. Post-Printing: Once the print is complete, you can enhance its appearance by gently brushing it with acetone if printed in ABS plastic, or apply a coat of paint to protect it from the elements. Alternatively, you can leave it as is, or use a smoothing technique to achieve a more polished finish.
