Door stopper with two-stage damper

Safely holds a door open and prevents it from closing on its own. The two-stage damper design dampens slamming (e.g. wind). Clip-on width 14mm. With different positions on the door, the desired open position can be set.  We use it because our cat can not open leaning doors  ;-)

Note: it is recommended to use PETG or similar matrials. PLA is not suitable.
