This is my first MyMiniFactory upload. The rest of my 3d objects are on Thingivers, but lately that website seems to be unstable.
I am using a 3d printed hot end and I wanted a Ender 3 styled cooling fan grill, but couldn't find one online. So I made a 40 mm fan grill. Then I made a 60 mm fan grill for my power supply fan (as the 40 mm grill isn't scalable to 60 mm). This is not for the stock Ender 3 metal Hot end fan setup.
I designed this fan grill to be printed flat on the bed, as the back side is completely flat. No supports! I noticed that some of the fan grills that I tried, have a gap where the fan blades spin, but have not come across a fan that needed this gap. Anyway, if you need to have a gap between the spinning fan blade and the grill, I have included a spacer. If the grill is causing interference with the fan, install the spacer.
This was designed to be printed with a 0.4 mm nozzle and 0.4 mm line width.
