Lego Head Tyre Valve Cap for Car/Bike Schrader

A lego-style head and helmet designed as a car/motorcycle/bicycle valve cap. This is oversized so about twice the size of genuine lego minifigure parts.

Filament:

eSun PLA+ 

Yellow

Notes:

This will print better/faster with very thick walls (8 is good). The overhang above the face piece of the helmet will print adequately without supports.

eSun yellow is a good match to yellow lego.

Tinmorry Red or Royal Blue look good for helmets

Post-Printing

You might need to snip off some stray filament if you print the helmet without support.

The head will push firmly into the helmet without glue. It's a tight fit but not difficult. The base of the helmet is slightly rounded and the head is cone-topped to make this easier. The tabbed side forces alignment.

The final diameter of the cap is almost 20mm, so some wheel trims might interfere with this.

How I Designed This

I've scaled up a lego minifigure helmet and modified the interior to be a simpler cone-topped cavity with a tab on one side, to prevent the head from rotating.

The head is a simple cylinder with a cone top, and a hollow centre to approximate a valve stem diameter. The head would not look correct without the helmet.

7th Mar 2024 - Uploaded a new Head "v6" part with threaded inner hole. This might fit your valve stem more easily. It's compatible with the existing Helmet "v5" part.
