Customizable Sliding Window Security Apparatus - Removal Preventer & Opening Limiter

thingiverse

When I'm 3D printing, I often leave a cracked open window and use a fan to suck out fumes, but this poses a home security risk. It's easy enough to keep a sliding window from being slid further by placing a pole in the track. However, that doesn't stop a potential intruder from lifting the window up and removing it from the track. This 3-piece design is for a customizable plastic bar that slips above the sliding window to prevent it from being lifted out of the track. Additional sections of the upper bar may be printed and connected together for wider windows (assuming your printer bed is smaller than your window). An end cap and clip hold the bar sections in place, preventing them from being pushed out from the opposite end of the window. Once installed, this 3-piece assembly can be left attached to the top of the window permanently as it has no effect on sliding the window open; it only prevents the window from being lifted out of the track. I've also added a lower track limiter that you can print in case you don't have a pole or something to keep the window from being slid too far. Additional segments can be printed and joined together for additional length with the printable peg. A grab tab sticks up on top, making it easier to lift out of the lower track when you need to slide the window open fully. Default parameters are set for an X-0 sliding window (X-O means the side that opens is on the right-hand side when looking at the window from indoors). For an O-X window, set the "window_opens_from_left_side" parameter to 1 or mirror left-right via slicer software. Window dimensions vary by manufacturer, so I'm including the SCAD file for you to customize. Default parameters in my SCAD file are set for a Don Young aluminum slider window. Note that this design is only for horizontal slider windows (window slides left or right on a track) or sliding doors, not for single-hung or double-hung windows where the operable window moves up/down.
