This a CAMLOCK Adaptor for the Bosch CM10GD Miter Saw.
43mm ID.
It may work on other bosch saws if they have similar dust ports. Let me know in the comments and I'll modify the description.
Printed at 0.2 with 25% infill and 6 wall loops for strength. Print with the cutouts side up.
The cutouts need support. I used the tree supports and they worked well.
Inner brim if you think it needs it.
You'll obviously need to print the camlock fittings too.
The author remixed this model.
Used the 43mm adapter and added the cutouts for the bosch saw dust port.
