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.
