NEW revision 2026-10-22 the original revision worked mechanically but didn't protect against water
A 3D-printable replacement rear fender for the BlueTouch BT2000 electric scooter, designed to survive rough roads, potholes, cobblestones, and Prague's infamous tram tracks.
The original plastic rear fender tends to crack under repeated impacts and vibrations. In my experience, its lifespan was approximately 1–3 months, depending on riding conditions.
I initially tried printing replacements from PLA and PETG. While these materials were sufficiently rigid, they repeatedly fractured during normal riding.
Switching to flexible TPU solved the cracking problem, but introduced another challenge: a flexible fender can bend too far and potentially contact the tire.
After 17 design revisions, the solution is a reinforced, curved TPU shell featuring:
Longitudinal reinforcing ribs.
A transverse rib to prevent the shell profile from spreading under bending loads.
Increased shell curvature for additional structural stiffness.
Slotted mounting holes for position adjustment.
The goal is to combine the impact tolerance of TPU with enough stiffness to maintain tire clearance.
Front or rear?
It fits both positions. For front position you may want to stop the print early and/or cut the shape with scissors.
Print settings
The model was developed and printed on a Creality Ender 3 with a 0.6 mm nozzle and Bowden extruder.
Parameter | Value |
|---|---|
Material | Alzament TPU 95A |
Supports | Organic, build plate only |
Print orientation | Mounting bracket down, fender tip up |
Expect approximately 14–15 hours of printing and substantial support material.
TPU is strongly recommended. Printing this model in PLA or PETG will not provide the same flexibility and impact resistance.
Files and modification
The editable FreeCAD source is provided so you can inspect or modify the design for your own scooter.
This is an independent, community-made replacement part, not an official BlueTouch product and not affiliated with the manufacturer.
Developed, printed, and tested in Prague, Czech Republic — where cobblestones make excellent durability testers.
