Karcher vc6 hose lock for Cyclone Dust Collector

Karcher vc6 hose fastening mechanism.
I make it for use PcTronics's Cyclone Dust Collector (Remix) with my Karcher VC6300 vacuum. I think it sutable for all VC6 series.

There are to versions:

• karcher_glued: this have stronger latch. You need to glue latch after printing.
• karcher_without_glue: This have weaker latch, but it's strong enough if you use it in static conditions (for CNC for example).
