Draft Shield for Extruder
Facilitate cooling of the top of the extruder. Can be fixed with double sided tape. I did not print 3D because the extruder is hidden and disappears and maintenance problems are anticipated.
Cut the OHP sheet of material and fold it. It cut with a laser processing machine. Place the acrylic board on the OHP sheet and cut at the same time. Acrylic board is useless, but it is necessary as a presser.
Added on April 21, 2019. By attaching this cover, air blowing to the teeth of the stepping motor of the extruder is stopped. There is an adverse effect of this. In some cases, the PLA filament became soft and could not be delivered. I recommend that you remove the cover and operate.
Perhaps, if it exceeds 30 degrees Celsius, this phenomenon reproduces.
PTFE tube too close to extruder. Therefore it melts. Stop sending filaments. It took me half a year to notice this problem. You can fix it with this cover.https://www.thingiverse.com/thing:3042175
