2,250 Free Wheel Combinations: MakerWorld Parametric Rim and Tire Generator
EngineerForge has shared a free browser-based wheel and tire generator on MakerWorld. Explore 15 rim styles, 15 tread patterns, 10 caps, 45 parameters and a snap-fit tire design.
2,250 base combinations and 45 adjustable parameters—without traditional CAD
Finding a wheel with the right diameter, tread pattern, rim design and mounting interface can be a challenge for RC vehicles, scale models, robotics and custom replacement parts. Ultimate Parametric Wheels – 2250 Combos | 45 Params, shared on MakerWorld, aims to simplify that process: users configure wheels in their web browser through parameters and sliders rather than designing each part from scratch in CAD.
The generator was introduced to the community by Máté Turner, posting under the name EngineerForge (@engineer.forge). According to the creator, the tool can be used free of charge and configured 3D models can be downloaded for printing. This article is based on the creator's description and the original images supplied with the announcement.
15 rim styles, 15 tread patterns and 10 center caps
The generator offers 15 rim designs, 15 tire patterns and 10 snap-on center-cap styles. Multiplying these gives 2,250 basic appearance combinations before taking the various dimensions and geometry settings into account.
Tread choices described by the creator include road, rally, off-road, tractor, crawler, monster-truck and sand-paddle types. Rim customization includes the number and thickness of spokes, outer lip depth and the concave or convex profile of the wheel center.
Dimensions and adjustable geometry
| Setting | Creator-stated range |
|---|---|
| Rim diameter | 25–120 mm |
| Wheel width | 8–60 mm |
| Tire sidewall thickness / profile parameter | 3–80 mm |
| Rim, tread and cap choices | 15 × 15 × 10 |
| Configurable parameters | 45 (creator's designation) |
The 3–80 mm tire profile value is reproduced from the author's description; its precise geometric meaning should be checked against the generator's controls. Not all extreme parameter combinations should be assumed to offer equivalent strength or printability.
Round bores, D-shafts and M2–M10 nut pockets
Users can select a round axle bore, a D-shaped shaft opening suitable for certain small motors, or a hexagonal nut pocket for M2–M10 metric nuts. The nut may be installed from the rear or concealed under a snap-on center cap at the front.
An M2–M10 nut pocket should not be confused with standard 12, 14 or 17 mm RC wheel-hex interfaces; suitability for a particular axle must be verified from actual dimensions.
Snap-fit tire attachment
Rims and tires can be printed as separate components. The creator describes a tire that snaps onto the rim, with four internal locking tabs intended to prevent the tire from rotating around the rim under load. This potentially makes it easier to combine rigid rim materials with flexible tire materials and replace a worn tread.
Fit and durability depend on printer accuracy, material properties, layer orientation and operating load. No independent torque, fatigue or wear test has been supplied to 3DPS.
The entire wheel can be printed as one piece!
Another practical feature of the generator is the option to print the entire wheel – rim and tire together – as a single piece. This eliminates the need to print the two components separately and deal with fitting and assembling them afterward.
This can be particularly useful for scale models, decorative prints, and simpler mechanical projects. Of course, axle compatibility and the finished wheel's load-bearing capability should still be verified for the intended application.
Custom sidewall lettering and center caps
Custom text can be added to the tire sidewall, or the generator can automatically display selected tire dimensions. This can be useful for scale-model realism, custom branding or identification. Several cap designs help conceal the axle mounting hardware.
How to try the generator
- Open Ultimate Parametric Wheels on MakerWorld.
- Select a rim, tread pattern and center-cap style.
- Set the dimensions, spoke geometry, axle mounting and optional sidewall text.
- Generate and download the corresponding 3D files, then prepare them in your slicer.
- Test the printed parts for fit, tire retention and strength before using them in a vehicle or mechanism.
What makes it interesting? The generator automates the repetitive dimensioning that makes one-off wheel design time-consuming. A separate rigid rim and potentially flexible tire are a practical approach for prototyping, hobby robotics, RC vehicles and scale modeling. However, the model is not a certified wheel system; mechanical validation remains the user's responsibility.
