Krafter, have you made any of these adapters and tested them? I want this!
To answer Matt’s question: For my version which is the max pump, no. The pump is not powerful enough to push air through the check valve.
An attachment like this would be a huge godsend. Krafter, If you’ve printed out any of these, I’d happily pay for one as I don’t have a 3-d printer. If you’re interested, can you send me your contact details?
