UNI-T UT120 multimeter wire organizer sleeve

PETG or other filament with similar flex recommended. Haven't tried with PLA but might work. Brim also recommended but depends on your confidence on your bed adhesion. Print with the probe holder part down on the bed. Needs a few supports.

To put it on slip the wires through the slit on the front and push the right side of the meter in. Then bend the sleeve and slip the left side in. Wires should be wrapped up and around and if the wire legth is the same as mine you should be able to hook them around the tab at the top and to the back and poke the probe tips in their holes.

You can also slide a probe between the probe holders from the bottom and achieve better usability.

The probe holes are intentionally very tight so depending on your printer you might need to clean them up a bit with a 2 mm drill bit. I don't recommend pushing them in with force, I pulled the tip out from one of my probes when pulling it out.

STEP file included.
