Fluke 87V dial
Replacement dial for Fluke 87V multimeter.
The larger notch on the hex shaft is for a 006 O-ring to hold the dial in place, but I couldn't get the support out of that small area and the support worked equivalent to the O-ring. May be stronger more effective without.
I printed this dial side down, hex shaft up. An alternate design worth exploring would be to change the hex shaft to a hex hole and glue a metal hex shaft cut from an Allen key. Could print knob right side up without supports for a better finish.
