No, but I have the 3D printed version clipped to my shirt at this very moment; I took that pen to work today. So far the answer has been slightly greater than 24 hours, because I put my 3D printed cap on it yesterday. Checking just now it started writing with no issue.

With the stock cap my 1.5mm Parallel will only require very minor bludgeoning starting after about 3 days of disuse, and will restart pretty easily if I give the nib a nice slow vertical wipe on a spare Post-it note or something. The nib plates on the Parallel are pretty flexible and you can press it against paper such that it spreads them apart slightly, which tends to get the ink re-flowing pretty easily.

There is no gasket in the stock cap, so I can’t imagine the printed one would fare much worse than original. Neither has an anti-choke hole, either.
