I was looking for a long vacuum nozzle to clean hard to reach spots in my car (specifically the place between the seat and the door).
The original nozzle is 20mm wide and it is too thick for what I needed, also it is too short.
Therefore I had a look at Thingiverse and found the 10mm design by Mart1n but it wasn't long enough (https://www.thingiverse.com/thing:2402488)
I simply made it longer, now 230mm so it can be printed on most printers, and it is perfectly working as expected, see the before/after picture.
Happy cleaning !
Print it standing up and no support is required. Depending on how good is your build plate adhesion, a raft/brim may be a good idea.
