Parrot Disco UV filter - ring to glue

[EDIT 2018-04-23] : improved version to print in Black and glue with neoprene (removable but wash writed black letters)

this is a simple ring to glue on disco nose for - v1 - in progress - NEED IMPROVEMENT - lost filter in landing -> filter need to be glue with ring

For 40.5 mm UV filter, CPL, ND4, polar etc etc ... Let the ability to superspose them with their thread on top (reverse)
