Today I construct a Compact RPE.
I do a few of these per week. This one happens to be made on a 3D Printed model. Also Called a 2 Arm RPE, some orthodontists like using these because they are more hygienic and low profile for the patient than the normal 4 arm RPEs.
The screw I prefer is the 8mm Leone Stealth Slender Compact RPE AA-1621
