Aluminum extrusion window frame latch

prusaprinters

<p>It seems like RV manufacturers love to use the flimsy aluminum extrusion-frame sliding windows, and the plastic sliding catches that hold them up are even cheaper. Our garage sliding door has those kind of windows, and the catches didn't even last a month, so I made replacement pieces for them. As you will see, the 3d object file is a combined left and right side. This should fit with minimal post-processing. However, I do print with a 0.8mm nozzle, so some nominal sizing may apply.&nbsp;</p><p>To get these out, simply pop the plastic corner piece at each end of the extrusion loose, and the catch slides out. (I've also made a file for those corner pieces…) Don't lose the spring!&nbsp;</p><p>I would strongly recommend printing this in PETG as it will be exposed to UV, and you should use 100% infill with &gt;5 perimeters for strength.&nbsp;</p>
