Nipple Caps for Grease, Air and Brake: STL Files

«Nipple Caps for Grease, Air and Brake: STL Files»

The models fall into a few groups. Caps for grease fittings are usually simple domes or shallow cups, sometimes with a small tail that keeps them attached. Fill port covers for air tanks and paintball regulators often need a tighter fit because they sit against pressure during filling. Caps for hydraulic brake bleed screws are smaller still and are frequently printed in a flexible material so they stay on the screw.

On the author's page, look at the stated inner and outer diameter and compare it with the fitting you have, since one part name covers several thread standards. Check how many parts the model includes and whether they snap or screw together. Read the material and layer settings the author lists, and look at photos of real prints to judge how the cap sits. If a cap has to stretch over a ridge, a stiff filament may crack.

Search terms differ from field to field, so try the wording used in each one: grease fitting, zerk cover, fill port plug, bleed screw cap, valve cap. Adding the device helps, for example bicycle, scooter, air rifle, paintball marker or brake caliper. Related items include dust covers, tools for removing the valve itself, and small organizers that hold caps and spare parts together.
