Description
This is a parametric multimeter probe tweezer. This parametric design shall fit all multimeter probes.
Support material is required on the build plate only. An infill of 30% is recommended.
This object was designed using openSCAD.

First suggested edit to better attach arms to probe holders is to replace:
cube( [ lct_ArmOutsideHorizontalOffset, lct_TweezerThickness, lct_TweezerHeight ] );
with:
rotate( [ 0, 0, -ProbeHolderAngle ])
cube( [ lct_ArmOutsideHorizontalOffset*1.1, ProbeHolderWidth, lct_TweezerHeight ] );
Second eliminates z-fighting issue inside OpenSCAD:
Replace:
difference() {
cylinder(d = lct_holderExternalDiameter, h = ProbeHolderWidth);
cylinder(d = lct_ProbeDiameter, h = ProbeHolderWidth);
translate( [ -lct_holderExternalDiameter / 2, 0, 0 ] ) cube( [ lct_holderExternalDiameter, lct_holderExternalDiameter, ProbeHolderWidth ] );
}
with:
delta=0.01;
difference() {
cylinder(d = lct_holderExternalDiameter, h = ProbeHolderWidth);
translate( [ 0, 0, -delta ] ) cylinder(d = lct_ProbeDiameter, h = ProbeHolderWidth+2*delta);
translate( [ -lct_holderExternalDiameter / 2, 0, -delta ] ) cube( [ lct_holderExternalDiameter, lct_holderExternalDiameter, ProbeHolderWidth+2*delta ] );
}
