Printed with bambu matte pla. Looks and feels great. Lightly filed the screw threads, once over with a brass brush, clean fit. It clamps well vertical on my moto g power 2020. The mount is just small enough to still slide freely in my RRS BH-55 but it's not alone in that. Edit: I decided to modify the clamp of my BH-55 to fix the problem for all affected plates, this one included. On the off chance someone with this ballhead runs across this, and at the risk of veering way off topic, the fix is: Press the pin out which holds the lever onto the shaft. Remove lever. Remove washers carefully, keeping their orientation. There will be a thrust washer at either end (or possibly just one by the lever.) Between them will be a bunch of Belleville washers. These are slightly conical and act as springs. By flipping some around so adjacent cones touch rather than nest you'll increase the deflection and allow for a wider range of plates. https://en.wikipedia.org/wiki/Belleville_washer#Stacking
