osVAC F32 Adapter Einhell TC-VC / Kraftronic KT-NT

Brings osVAC to Einhell wet/dry vacuum cleaners.
Unlike existing designs like [https://www.printables.com/model/360728-osvac-einhell-vacuum-cleaner](OSVAC Einhell vacuum cleaner) and [https://www.printables.com/model/991343-osvac-einhell-tc-vc-adapter-with-m32](osVAC Einhell TC-VC adapter with M32) I wanted it to have

• a sturdier lock
• a lock that actually latches like the original
• a female F32 connector as is standard for vacuum cleaners
• a look similar to the original (just for fun).

Print with tree support for overhangs beyond 65°

Update 2026-03-18: Added a version with slip ring. To loosen the slip, I clamp the end that goes on the vaccum cleaner in a vise, using a folded towel to protect the plastic from scratches. Then, with another protective towel and a plumber wrench, I twist the other end until it cracks loose.

Update 2026-04-30: Added an adapter for using the original Einhell accessories via the tapered aluminum pipe connector.
