This strand is great! I printed with BED 50C ° nozzle 230-225 ° C without using fan;
Remember that the 3D printing does not produce smooth parts, and bacteria can hide inside cavities of layers; try to print parts with low resolution to minimize the problem.
The parts to be printed are 3 to use less support;
The handle has a thread that is screwed to the mold; you can screw-unscrew easily!
Good dinner!-
