Bottle rinser (for homebrewing etc)

thingiverse

Simple design for rinsing bottles for cleaning before bottling. This rinser can use both compressive spring internally, but as i find those hard to find just right i also made this to use any appropriate extending spring that are easier to source. Suppose it could also work with rubber bands. Springs are about 40mm long. Special note about printing, the "Grill" part could need some tweaking for tolerances on the threads. I adjusted it to -0.5mm horisontally and it screws in easily. It does not take much strain so tolerances can be rather loose. Sharing free for other homebrewers out there, but please contact me if you want to use these files commercially.
