WIP
The tip with the nubs should be printed out of TPU. Its purpose is to allow drilling at angles without the bit walking away. The adapters are for smaller bits you'd typically use on walls. I recommend printing it with just build plate supports, the main body should be face down (The “tail” where the drill bit goes in should face up). May need to glue the TPU tip on if using it with vigor. 32mm hose size (google said it was standard for vacuum hoses).
The author marked this model as their own original creation.
