Laser Enclosure Vent with Cap (to suit 53mm hole)

thingiverse

This vent is intended for laser enclosures, printer enclosures, or any other housing which sometimes needs ventilation, but also needs to be blocked when not in use. Simply twist the plug in to install it, and twist it out then pull it out when you need to seal the chamber. Requires a 53mm hole drilled in the enclosure, and is intended to be used with 17mm thick formply (but will work with any thickness of material). V1 is the version that I've printed and tested. V2 is an improvement that reduces the amount of filament used for the plug, and also incorporates a "back side" vent fitting, which goes on the other side of the enclosure wall, and incorporates a finger guard\vision blocker (useful for laser enclosures). Note: apologies for the left-handed thread on the plug. I didn't realise until after I printed it, that I had done the thread the wrong way. it doesn't affect the functionality, but it's not "normal". you can just mirror the plug half to correct this before you slice it.
