Bosch GCM8SJL circular saw vacuum hose adapter 50 and 40mm (screw-in)

thingiverse

Update 2019-06: v2 with improved clip flaps. Looking for a way to connect my non-Bosch workshop vacuum to the GCM8 SJL miter saw, I came across Ruperts design. It looked appealing but was angled, which wasn't needed and made it cumbersome to print. So, I took Rupert's part and used his clip-lock design to create a much smaller and easier-to-print version. The fastening clips of the original design turned out very flimsy and broke off quickly on the first attempt. I modified them to be stronger and stick out more because the original design didn't plug in firmly enough and came off by itself several times. The two objects allow you to connect either a 50mm (DN50) or a threaded 40mm sawdust vacuum hose to the Bosch GCM8 SJL miter saw. The 50mm model goes over the adapter, and can also be used with off-the-shelf DN50 pipe tubing. The 40mm variant can be screwed into the adapter. By looking at the two objects, it should be clear which is which. If you want or need to make adjustments, go ahead and tinker with it! If 50mm isn't manly enough for you, take a look at this adapter for 60mm hoses. I would also like to recommend my cheap cyclone dust extractor project - just in case you're still searching for something to stick the other end of that hose to.
