Keep Students Practicing — Even Without Their Instrument

The Valve Practice Block helps students continue building valve coordination and finger patterns even when their instrument isn’t available.

It’s a great solution for situations like:

• students who forget their instrument at home
• students who can’t take their instrument home
• students who don’t have a quiet place to practice
• students who want to practice fingerings anywhere
• students with temporary limitations who still want to participate

Instead of sitting out, students can stay engaged and continue building muscle memory and coordination.

Assembly Overview

Assembly is quick and requires no glue or special tools.

  1. Press the keyboard switches into the body from the top
  2. Slide the top into place using the dovetail
  3. Insert the valve/button pieces
  4. Slide the bottom into place to complete the housing

The switch openings automatically align with the valve positions.

Printing Information

Print Difficulty: Easy

Supports: Minimal

Estimated Print Time: ~1–1.5 hours total on a Bambu P1S

PLA is recommended for best results, though PETG should also work well.

Minimal supports are required under the internal valve openings on the body piece.

Additional Hardware Required

To assemble the practice block you will need:

3 MX-style mechanical keyboard switches (Generic ones work)

These switches act as the spring return for the valves.

Common examples include:

  • Cherry MX style switches
  • Gateron switches
  • Kailh switches

***Linear switches are recommended for the smoothest feel.***
