Munchkin Baby Gate Pin

thingiverse

This is a replacement part for a Munchkin Extending Extra Tall and Wide Metal Baby Gate (http://www.munchkin.com/extending-extra-tall-and-wide-metal-gate-white.html). The part is the lower hinge pin that seems very prone to breakage over extended use. I created the first replacement part from hardwood, and that did not last. Let's see how long this will last. Print Settings Printer Brand: LulzBot Printer: Mini Rafts: No Supports: No Resolution: 0.4mm layer height Infill: 100% Notes: I used pretty rough resolution (0.4mm layer height) because this part is not that visible. I used 100% infill because the part is relatively small and I wanted it as robust as I can make it. I used 3mm PLA filament. Post-Printing You may need to enlarge the hole for the metal screw slightly. It is pretty snug. I used a 20min epoxy designed for plastic parts to adhere the metal screw in the pin. How I Designed This I designed the part in Autodesk 123D Design. It is a simple design with only one cylinder (the pin) joined to a cube that has a hole for the metal screw (under the model during printing, see the picture). The only critical measurements are the size of the hole in which the metal screw goes, and the overall dimension & fillet of the "head" as it needs to be able to rotate horizontally about the pin. The top of the head could be reduced. This was my first version so I went for extreme robustness.
