Print the screws with >50% infill to provide enough strength to clamp together “ring top” and “ring-bottom” files.
I would suggest printing “ring top file” at 30-45 degree elevation to minimize print time, if using a Monoprice Mini
I made two of these units and found that the outer diameter of the Zevro dispenser has small differences. In order to circumvent that problem, I would suggest to buy the dispenser first and measure the outer diameter to compare with that of the ring before printing the top and the bottom rings. Usually the difference is small enough that it can be circumvented with minor tweaks.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
