Cetus Draft Shield for Extruder

Draft Shield for Extruder Easily cool the top of the extruder by installing this shield. Securely attach it using double-sided tape to prevent any issues. I opted not to print 3D models previously due to the extruder's hidden position and potential maintenance problems that arose from it disappearing during use. To create this draft shield, cut an OHP sheet into a suitable size, fold it neatly, and then use a laser processing machine to shape it. Next, place an acrylic board on top of the OHP sheet and cut both simultaneously; although the acrylic board is unnecessary, it serves as a presser. Added on April 21, 2019: By attaching this cover, air blowing towards the teeth of the stepping motor in the extruder is blocked, causing an adverse effect. In some instances, the PLA filament becomes soft and fails to be fed through. I recommend removing the cover for optimal performance. It's possible that if the temperature exceeds 30 degrees Celsius, this issue will recur. PTFE tubes positioned too close to the extruder melt due to overheating, resulting in a halt of filament supply. It took me six months to identify this problem; this draft shield can be used as a fix. https://www.thingiverse.com/thing:3042175
