Bosch Professional 4-way distributor dust collection

In order to collect the saw dust from my woodworking machines, I created a 4-way valve to easily redirect the vacuum hose from one to another machine. This to prevent to disconnecting and connecting the vacuum hose every time one switch machines. For this a standard DIY vacuum cleaner (Bosch Professional GAS 35 L) is used.
I purchased a slightly large diameter hose (internal diameter 38 mm vs standard 32 mm) than the original hose to prevent loss of vacuum power (due to its longer length).
For the hoses an anti-static designated vacuum hose (1x2m, 2x3m & 1x4m) is being used (https://www.slangenboer.nl/stofzuigerslang-zwart-as-38-mm).
It works fantastic! Saves me every time switching the hose between the machines.
And for all the other (not Bosch Professional) machines I designed/ printed the typical Bosch hose connectors.
I'm also working on a smaller 2-way distribution valve since I use my machines also on location.
