This is a lightweight, easy-to-print collection of 10 protective cap types designed to fit the most common power connectors used in electronics, RC, and DIY gear.

Features: 

• Compatible with PLA & PETG – no TPU needed

All caps personally tested on real devices – perfect snug fit.
However, for optimal results, you may fine-tune the scale ±1% based on filament or printer tolerance.

If you're missing a specific type of plug, feel free to let me know—I'm open to adding more types!

Happy printing and keep your connectors safe!

P.S. If you are looking for a solution to reduce 3D printer noise, have a look on my soundproof enclosure design crafted from IKEA furniture. This enclosure reduces printer noise and ensures impressive 36.5 dB(A) at just 1 meter away. Detailed instruction how to build it you may find here.
