Stepped Rod 4mm to 1.5mm

Stepped Diameter Rod with Handle
A simple measuring/feeler tool featuring stepped diameters from Ø1.5 mm to Ø4.0 mm in 0.5 mm increments, each 10 mm long. The rod includes a smooth 30 mm handle for easy grip. Designed for testing hole sizes, clearances, and print accuracy.

I added a negative text to engrave my logo name on the side , feel free to do the same.

📐 Model Specs

Steps: Ø1.5 → Ø2.0 → Ø2.5 → Ø3.0 → Ø3.5 → Ø4.0

Section length: 10 mm each

Handle: Ø12 × 30 mm (smooth cylinder)

Total length: 90 mm

⚙ Recommended Print Settings

Layer Height:

0.16–0.2 mm for a balance of accuracy and strength

0.12 mm if you need the most precise diameters

Perimeters (walls):

3 or more for a solid handle and robust rod

Ensures strength even on the thin Ø1.5 mm section

Infill:

20–30% (gyroid or grid). The handle is thick, so strength mainly comes from perimeters

Top/Bottom Layers:

At least 5 top and 5 bottom layers for durability

Print Speed:

Moderate (40–60 mm/s)

Slow down outer walls (25–30 mm/s) for the smoothest surface finish

🏗 Print Orientation

Vertical (handle on the bed, tip pointing up):

Best for dimensional accuracy on each diameter

Stronger along the length of the rod

Horizontal:

Easier to print, no tall object wobble

Thin tip may be weaker (layer lines perpendicular to rod length)

🎨 Material Choice

PLA+ → easy to print, good dimensional accuracy

PETG → stronger, more impact resistant

ABS/ASA → for outdoor or higher-temperature use
