WheelCapDesignerHub cap generator – design & 3D-print custom wheel center caps for free
Lost, faded or cracked a center cap? With WheelCapDesigner you design a perfectly fitting wheel center cap (hub cap) in minutes, preview it live in 3D, and download it as an STL or a colored 3MF for 3D printing — completely free, no signup.
Design your center cap →How it works
- Enter measurements. The outer diameter and the clamp/mounting diameter of the wheel opening. Tip: measure on the wheel — the clamp Ø drives the fit.
- Pick a logo. A built-in shape (star, hexagon, rings …), text, or your own SVG. Place, rotate, scale it — raised, engraved or flush two-color.
- Check in 3D. Rotate the model live, set cap and logo colors, verify the clips and the fit.
- Download & print. As an STL (single color) or a 3MF with separate, colored objects (perfect for multi-color / AMS). Ready for Bambu Studio, PrusaSlicer & co.

FAQ
Is the hub cap generator really free?
Yes. WheelCapDesigner runs free in your browser — no signup, no installation.
Which measurements do I need?
Two: the visible outer diameter and the clamp/mounting diameter of the wheel opening. Measure on the wheel — the clamp Ø is what determines the fit.
STL or 3MF — which one?
STL for single-color prints. The 3MF contains cap and logo as separate, pre-colored objects — ideal for multi-color / AMS, no manual painting.
Will the printed cap stay in the wheel?
Yes, thanks to adjustable snap-in clips. If it's too tight or loose, just tweak the tolerance for your printer.
Can I use my own logo?
Absolutely — upload an SVG or use built-in shapes and text, optionally flush two-color for top-down printing.
Which material should I use?
For outdoor use, ASA or PETG hold up better than PLA (UV/heat). Darker colors age more slowly.
