Shop vac adapter for one-man wall drilling

Need to drill a hole into the wall, but have no shop vac assistant? This attachment holds itself to the wall with the vacuum of the shop vac. I redesigned the main body to be thinner. Provides better visibility of your marks for the hole on the wall.
It has a swivel right angle connector for 35mm shop vac hoses. The snap-in ring keeps everything together.
You'll need to put some self-adhesive weather sealing strips into the 10mm groove in the main body.
