Inspired from https://www.thingiverse.com/thing:2907583 Modified for printers with smaller print beds such as Monoprice Select Mini Electronics used: 1. A D1 mini pro or a regular D1 mini will work equally well, available at https://www.amazon.com/gp/product/B07333L9VR/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 2. A servo is required, available at https://www.amazon.com/gp/product/B00CBTXQWW/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 3. A dispenser is needed, available at https://www.amazon.com/gp/product/B0009MGQUC/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 Tips: 1. Print the screws with more than 50% infill to provide enough strength for the "ring top" and "ring-bottom" files to clamp together. 2. To minimize print time, I suggest printing the "ring top file" at a 30-45 degree elevation if using a Monoprice Mini. 3. After making two units, I found that the outer diameter of the Zevro dispenser has small differences. To solve this problem, measure the outer diameter of the dispenser before printing the top and bottom rings. Usually, the difference is small enough to be circumvented with minor tweaks.
