Sunlu S1 5015 blower fan holder. No need for any modification of outer shell of the FilaDryer. It just hooks between the top and bottom shell.
It partially blows air around inside the dryer and out of the dryer.
For power I use solderles solution with, 24v blower fan
and Y splitter DC cable, like this
and Female Barrel Connector like this
Inspired by this man's solution.
Printed with prusament PETG. On ender 3 v2. With 0.20mm layer height.
I modified this in tinker cad. So beware, there may be flaws to the stl file.
