MTB Tubeless & Emergency Workshop Kit – Essential Presta Tools and Trail Repair Set

This collection brings together seven essential 3D-printable tools designed to solve the most common MTB maintenance problems, from tubeless sealant service to brake inspection and emergency drivetrain repairs.

Rather than a random set of parts, this bundle is designed as a compact maintenance toolkit focused on real workshop and trail situations. Every tool addresses a specific problem riders eventually face: messy sealant refills, stuck valve cores, worn brake components, lost small parts, or unexpected mechanical failures during a ride.

All models are optimized for fast and reliable FDM printing, require no supports, and are designed to be lightweight, practical, and durable.

Included tools

This bundle includes seven practical workshop and trail maintenance tools:

• Screw-On Presta Valve Funnel – stable and clean tubeless sealant filling
• Valve-Fill Funnel – compact direct-insert funnel for precise refills
• Valve Core Holder + Tool Organizer – keeps valve cores and tools organized with magnetic base
• Presta Valve Cap with Integrated Core Tool – protective cap with built-in removal tool
• Dual-Hole Presta Valve Core Remover – dual-method tool for removing tight valve cores
• MTB Brake Pad Spacer & Rotor Wear Gauge – multifunction brake maintenance tool
• Emergency UDH Derailleur Hanger – temporary emergency solution for drivetrain failures

Designed for real maintenance situations

These tools were designed from real riding and workshop experience, focusing on solving practical problems instead of adding unnecessary complexity.

Typical situations where this kit becomes useful:

• Refilling tubeless sealant without spills
• Removing clogged or seized valve cores
• Keeping small valve parts organized
• Checking brake pad and rotor wear
• Safely servicing brake calipers
• Carrying emergency repair solutions on long rides
• Preventing small mechanical issues from ending a ride

Key advantages

✔ Practical real-world tools
✔ Compact and lightweight designs
✔ Fast and easy to print
✔ No supports required
✔ Compatible with standard Presta valves
✔ Ideal for MTB, gravel, road and e-bikes
✔ Suitable for both workshop and trail kits

Brake tool functionality

The included brake maintenance tool combines a pad spacer and wear gauges in one compact design.

Measurement slots allow quick inspection of:

• 180 mm rotors (1.55 mm wear check)
• 200 mm rotors (1.7 mm wear check)
• Brake pad friction material thickness

Regular inspection takes only seconds and helps prevent loss of braking performance or rotor damage. This is especially important for e-bikes due to higher loads and braking stress.

Important notice

The Emergency UDH Derailleur Hanger is intended only as a temporary emergency solution. Replace with an original hanger as soon as possible. Not intended for aggressive riding or long-term use.

Why this collection exists

Small tools are often the difference between fixing a problem quickly or ending a ride early. This kit focuses on the small but critical tools riders usually realize they need only after something goes wrong.

Printing recommendations

All parts are designed for common materials such as PLA, PETG, or similar filaments.

Suggested settings:

Layer height: 0.2 mm
Infill: 20–40%
Supports: not required
Perimeters: 3 recommended for durability

For the Valve Core Holder, a Ø10 × 3 mm magnet can be optionally installed.
