A folding kickstand for the Unity UN202 clamp meter. It mounts under the top case screw (the one just below the jaw). The leg folds flat along the back and swings out against a hard mechanical stop at 35°, so once it's open it can't open any further and the meter won't slide down flat while you work with both hands. It doesn't depend on hinge friction to hold the angle.
How it works
Hard stop: a short tail behind the hinge axis lands flat on the base plate at the deploy angle. Meter, leg and table form a rigid triangle.
- Hinge: 12 mm leg knuckle between two 7 mm cheeks, 0.15 mm clearance per side, M3 cap screw with the head and nut sunk into the cheeks.
- Y foot: the leg forks into two feet 40 mm apart, so together with the meter's bottom edge you get a wide support triangle.
- Base: sits on two flat rails along the convex back so it can't rock, and side rails cradle the folded leg.
Files
base: print as exported (rails on the bed), no supports. The hinge bore is a teardrop.
- leg: print flat as exported, supports touching build plate only (the stop tail sits about 3 mm above the bed).
- leg_test: short stub, print on its side with no supports. Print it together with the base first to check the fit and the stop before printing the full leg.
STEP files are included for each part (real B-rep solids, not meshes).
Hardware
Hinge: 1x M3x25 socket head cap screw (DIN 912) + 1x M3 nut.
- Case screw: 1x replacement screw (~3 mm shank, head 5 mm or larger) + 1x M3 washer (7 mm OD). Its length must be the original screw's length plus about 10.5 mm.
Assembly
Remove the top case screw.
2. Place the base over the screw hole with the hinge toward the meter's bottom end. Pass the replacement screw through the washer and the base and drive it into the original hole.
3. Drop the M3 nut into the hex pocket, slide the leg knuckle between the cheeks and push the M3x25 screw in from the counterbored side.
4. Tighten until the leg stays where you leave it when folded.
