I dropped a can of shaving cream on my shower floor, and the plastic top broke off! I made this to replace it - it's not nearly as nice as the original plastic top, but it's small, quick to print, and does the job just as well. It'll probably work for other aerosol cans that use a 4mm nozzle that dispenses when pressed down.
Shaving_Cream is an older STL that had a problem with it.
Shaving_Cream_MK2 is identical, but shouldn't require drilling.
Shaving_Cream_MK3 has a circular dispenser push thing.
.4mm nozzle; .125mm layer height
100%, but it doesn't matter.
I used PLA. I strongly recommend a fan on your extruder, as the part is quite small and printing without it is likely to mess it up. Raft is strongly recommended. Supports aren't needed. Print slowly, around 40mm/s, for best results.
Print Shaving_Cream_MK2. This won't require drilling.
If you decide to print the MK1, you will need to drill out the center with a 1/16" bit. This is because I am really bad at 3D-modelling and made this thing in half an hour.
