Flashforge creator Fan Bracket thing

thingiverse

I wanted to use this fan duct on my Qidi printer which is a FlashForge Creator clone that's also a Markbot Replicator Dual clone. To do this, I needed super long M4 screws but unfortunately, I didn't have any and wasn't willing to wait three weeks for them to arrive. I tried modifying the duct but was having trouble figuring out how to get it into SketchUp using multiple CAD software. It was like playing a frustrating game of import-export, where nothing seemed to be working as planned. Then, I stumbled upon this thing: https://www.thingiverse.com/thing:486566, which worked pretty well but didn't have any height adjustment capabilities. So, I decided to create something similar that would allow me to secure the bracket using the two slits above the bearings and adjust the position of the duct. The two nubs on the bracket fit perfectly into the two slits above the front bearings, providing a secure hold. The bracket attaches to the duct via two M4 bolts, allowing you to adjust the height of the duct as needed. With very little sag when using the bracket, you can get the bottom of the duct right down to the extruder nozzle outlet without interfering with your print.
