Made to mount my watering shower heads instead of leaving them lying around.

I printed 4 in ESUN Grey PETG with 100% infill and no supports. will see how the prints hold up over time

the mounting hole is a 4.4mm hole with a 1.8mm countersunk chamfer. if you're using 8g screws this should fit in. I used 10g as it was what I had on hand. I set my drill in reverse and reamed the hole till I had a slip fit. 

all 4 mounted perfectly with no splits using an impact driver set to the lowest setting
