Summary
Modular, stacable system to keep ER32 collets tidy and easy to access. Each module locks to the next so you can build stable vertical “towers” on your bench, tool cart, or drawer. Designed for standard ER32 collets.

Highlights

• Stacable & Modular:  scale the tower as you grow.
• Fast Access: dedicated pockets prevent rattle and make inserting/removing collets easy.
• Stable Base: geometry tuned to resist tipping, even when partially loaded.
• Easy Print: no supports, simple orientation, low material use.
• Shop-proof: rounded edges and reinforced walls for daily use.

Recommended Print Settings

• Material: PLA+ or PETG (choose PETG for warmer/humid shops).
• Layer height: 0.20 mm (quality) | 0.28 mm (fast).
• Perimeters: 3–4 | Top/Bottom: 4–5 layers.
• Supports: Not required.
• Orientation: print with the flat Top on the build plate.

Assembly & Use

1. Print as many modules as you need.
2. Align the guides and press to snap together.
3. Drop ER32 collets into each pocket.
4. For transport, hold the tower by the base and top.
