My mini shower head was too much for the wife.. So, this one has full flow with a softer feel. Bent at 45 angle to line up with most US shower extensions. This is also made to work at multiple angles. Flip your extension pipe 180 degrees for a taller shower. The LG suffix is the original. The no suffix file is has a scaled down fan for smaller showers. If someone would like to mod this and install a flow control.. Have at it. The IGS file is included. Print with the outlet port facing the build table. .1 to .2 infill should work fine. Print with more than 2 shells if your setup has gaps. I am in the middle of printing this, thus have yet to find out how well the pattern works
