Description
A TPU lock to avoid the pen opening itself while pocket carrying it.
After getting my pants ruined because my Lamy Safari opened itself on my pocket, I designed this simple lock to maintain it closed and avoid future accidents.
Print it with TPU, I used 3 walls at 0.2 layer high and 0.4 nozzle, no supports needed.
