Hinged Fan extension for "Printrbot Simple, 300mm Y Axis-No Sag!"

thingiverse

This is a hinged variation of FablabMoebius' Fan extension for ijamjonlawrence's Y axis No Sag design. I appreciated FablabMoebius' solution to prevent the iamjonlawrence's YFront piece from overheating and deforming, but found that the fan was obstructing my access to the extruder when I needed to change filament or clear a jam. My solution is a hinged part with no risk of coming apart during printing. It's now possible to enjoy optimal cooling without compromising easy access to the extruder. Additionally, I smoothed out several corners and added a cable tie loop for improved wire management, removing the lip on the upright piece that made it challenging to connect to the printer. For further details regarding the print settings, please refer to the instructions tab. Update: After learning from a user who experienced issues with the original design moving around during printing, I have updated the model by adding an additional file (SwivelFanMountWithPegs.stl) that includes two pegs for securing it with a small rubber band. Although I haven't printed this modified version yet, the necessary changes are minimal and won't cause any problems. Instructions Your printer needs to be properly calibrated in order to work effectively with the hinge system. When printing this upright part, ensure to enable support (rotate 90 degrees on the X axis). Print settings include PLA material, support structure, 0.2mm layers, and a moderate level of infill (40%). For securing the top mounting hole, use an M3x20 screw; for the other holes, M3X16 screws will suffice. With my heatbed in operation, I adjusted it to 50 degrees initially and then 40 degrees afterwards for optimal print settings (noting that a heatbed is not essential if printing in PLA). After the print is complete, carefully break off support material and gently bend the part back and forth in the direction of hinge rotation until you feel the hinges release.
