Configurable sockets and plugs for Karcher WD hose (fusion 360)

This is a configurable model - read carefully before printing!

Description

This model is meant for Karcher hoses with spring washer connector - hose code 4.441-066.0, commonly used with WD3 and alike, for connecting it to various power tools.

There are two types of the connector - plug (or “make”, meant to be inserted into a receptacle) and socket (or “female”, meant to accept the pipe from the power tool). To ensure tight fit the connectors are a bit tapered - for a plug connector, an upper diameter should be LESS that the lower diameter and vice-versa for the socket. See the pictures below for the explanation of the parameters.

Printing

Depending on your printer precission you may want to add / remove 0.5-1mm from your diameters for the connectors to fit. 

It's best printable with tree supports (simply to keep the clip holes pretty), at a standard 0.2 resolution. PLA recommended because of the flexibility.

Information

The bottom part has a bit peculiar shape - it's made this way to ensure it's airtight. There is a special transition zone to accomodate from the connector diameter (~37mm) to whatever size connector you need, and it can be more than the transition_length you've specified to avoid having angles less than 45 degrees. 

Some common sizes are included, use them at your risk. 

Commercial use is prohibited.
