🚲 Rack Tube Protection – Bike Rack Tube Protector

I designed this sleeve because the middle tube of my bike rack gets damaged quickly. Once the factory paint wears off, the metal starts to rust. To prevent this, I created a protective clamp-on sleeve that you can easily place around the tube.

Why this design?

  • Protects against rust by shielding the tube from rain, sand, and road debris.

  • Ventilation holes so moisture doesn't get trapped inside.

  • Clampable (open on one side) so you don't have to slide it over the end of the tube.

  • Reinforced rims on top and bottom for extra strength and a clean finish.

Print settings I used:

  • Material: PETG (or ASA for better UV resistance)

  • Walls: 4

  • Infill: 15-25% (not very critical due to the thickness)

  • Layer height: 0.2 mm

OpenSCAD File

The .scad version is fully parametric. You can easily adjust the following values:

openscad

tube_d = 26;      // tube diameter (measure with calipers)
clearance = 0.30; // extra clearance for a good fit
wall = 2.5;       // wall thickness
height = 240;     // height of the sleeve

Feel free to modify, improve, or personalize the design. If you make an even better version, I'd love to see it!
