FLSUN QQ Extruder part

thingiverse

This is an extruder part of the FLSUN QQ delta printer that may break, much like mine. I'm publishing this on behalf of FLSUN, who kindly sent me the STL file at my request. Unfortunately, my model broke after just two months of use. I printed the STL model using another printer and it's working perfectly now. The original STL model was placed vertically for printing the spikes correctly, which hold springs in place. I've also included a 90-degree rotated version that I believe is stronger due to the direction of pressure applied. A downside to this design is that the spikes are now hanging, making them potentially more difficult to print. Several similar models have been published already, but they differ slightly from mine.
