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

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, which looked appealing but was angled, which I did not need and which is cumbersome to print. So I took ruperts part and used his clip-lock design to create a much smaller and easier to print version. The fastening clips of the original design came out very flimsy and broke off quickly on the first attempt. I modified them to be stronger and stick out a bit more, because the original design did not plug in firmly enough and came off by itself a few times.

The two objects allow you to 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 whilst the 40mm variant can be used to screw the hose 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 is not 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 are still searching for something to stick the other end of that hose of yours to :-)

Supports: No
Resolution: 0.15mm
Infill: 25%
Filament: ICE ABS+ black 

Notes: 

It should be no problem to print this in PLA.

Two very small nibs have been added below the protruding clips to make sure the overhang prints properly for FDM. They can easily be removed with a knife after printing.
