Adapter for Flextail pump and Pinguin sleeping pad

None of the adapters included with my Flextail air pump worked well with my Pinguin sleeping pad, so I had to create my own one. Multiple models of the air pump have the same adapters - use the one with threading on the inside. Pinguin sleeping pads have the same, so called, “dual layer flat valve”, and the adapter fits right in.

Print settints:

• 0.12 layer height (didn't try higher, worked fine with the threading)
• use brim in case of low adhesion
