Prusa i3 X Pro Fan Bracket

thingiverse

I made a custom bracket to hold a 40mm fan blowing over the Prusa i3 x Pro Acrylic Black version's controller board driver heat sinks. The bracket has two slotted 3mm holes lining up with the 2 x 3mm slotted holes in the acrylic, providing plenty of movement and flexibility. Printer Settings: Prusa i3 X Pro Rafts: No Supports: No Resolution: 1.5 Infill: Honey comb at 45% Notes: I printed on a glass bed starting at 65 degrees, then dropping to 60 about a third of the way through. My nozzle feels gauge was set at 0.06mm off the build plate, and my initial temperature was 200 degrees before ramping down to 198 for the main print side. As soon as I switched to vertical mode, some wispy bits formed, so I reduced the temp to 194, then 190, and finally settled on 189. The printed section is relatively short at just 50mm long and 3mm wide, leaving little time for it to cool before moving on to the cooling fan and new rear print head bracket. My hope is that these upgrades will resolve any issues I've encountered. I created this object in Fusion 360. While I'm still getting familiar with the program, I find its simplicity and ease of use very appealing. To start, I drew the main section on the Y plane, using two squares to define the main portion and side stiffener. I then added a 38mm circle, along with a cross, which I offset by 0.75 units to create the centered at 10mm. From the outer edges of the circle, I formed a box where I placed the four 4mm mounting holes. These were positioned exactly 32mm from the center dim measured on my fan.
