Bosch GKS /GST 12V osVAC connector

thingiverse

This osVAC adapter fits the Bosch 19mm dust extractor connection. Tested on my 12V circular saw and on the multi cutter (Stichsäge). There are two versions of the adapter, a larger one where the osVAC connector is at an angle and a tiny one, which fits directly on the connector. For sealing and a tight fit I used an O-ring 20x27x3.5mm but you can also use some tape to achieve a tight and permanent fit.
