How it works
Measure the width and height of your window track. The clamp sits on the track and stops the slider at the desired spot.
The stopper is meant for ventilation positions and keeps the window from sliding while driving or in wind. It is not burglar protection.
Printing notes
- Print with the opening facing up, no supports.
- Use PETG or ASA, a caravan can exceed 50 °C in summer.
- The detents hold by friction. If the stopper is loose use 0.1 mm less clearance.
Common questions
Does the stopper protect against burglary?
No. Printed parts do not replace a lock. It only keeps the window in position.
Which sizes do I need?
Width and height of the track, best measured with calipers where the stopper will sit.
