Metal shelf mounted paper towel roll holder

This roll holder is meant to fit a 30 cm (11,8 in) shelf with 9 mm (0,35 in) holes 4 cm (1,57 in) apart, also known as my own shelf. If somebody would like a different arrangement send me the measures and i'll edit it.

There are two sets of files, the 'L' ones are for big size rolls with external diameter 27 cm (10,62 in) and hole diameter 7 cm (2,75 in), the 'S' ones are for standard kitchen rolls with external diameter 15 cm (5,9 in) and hole diameter 4 cm (1,57 in). I test printed only the L set, in case of issues with S files please let me know
