INTRODUCTION 
Precision makes all the difference. This modular spacer set was developed in my workshop to solve the common problem of positioning objects at fixed, precise distances. Whether you're aligning wall brackets, assembling furniture, or positioning components for electronics projects, this set of shims is the ultimate tool.

KEY FEATURES

Complete Range: The set includes spacers from 1 mm to 40 mm, covering all your alignment needs.

Modular System: All pieces are designed to be combined: you can add shims to obtain customized intermediate measurements.

Ergonomic Design: Rounded edges for easy handling and a stable base for placing them on any surface.

Clear Identification: Each piece is engraved or embossed with the measurement to immediately identify the correct shim.

WHY HAVE THEM IN YOUR LAB?

Wall Alignment: Perfect for mounting supports (like my Pokémon card holders) at exactly the same distance.

Machine Setup: Useful for calibrating heights or stops on lasers, CNCs, or 3D printers.

DIY & Woodworking: Excellent as temporary reference blocks during gluing or assembly.

TECHNICAL SPECIFICATIONS

Material: PLA (recommended for its dimensional rigidity).

Print Setup: Optimized for fast printing (a 10-15% infill is sufficient).

Accuracy: Designed with tight tolerances to ensure the actual size matches the nominal size.

INSTRUCTIONS

Print the complete set or just the spacers you need at the moment.

Combine the blocks to get the desired size (e.g., 10mm + 5mm = 15mm).

Use the spacers as a "third hand" to hold your items in place while you attach screws or double-sided tape.

AUTHOR'S NOTE
I created these blocks because I was tired of searching for rulers or improvised shims while mounting my wall projects. They've become my most used accessory! If you need a specific measurement not included in the set, let me know in the comments.
