This TPU stem cap protector is designed to cover and seal the handlebar stem screw on your bike — keeping out dust, dirt, and water while giving your cockpit a clean, finished look.

Like my other TPU dust caps, it’s printed in flexible TPU, which makes it durable, easy to install, and perfectly snug. Simply press it into place — no tools required.

Ideal for MTB, gravel, and road bikes, this protector not only keeps your bolts clean but also helps prevent corrosion and ensures smoother maintenance.

Printing tips:

  • Print one by one and slowly to avoid stringing.
  • Don’t print too hot — 205 °C gave me the best results without bubbles.
  • Clean the print bed with alcohol for better TPU adhesion.
