CNC Endmill & Bit Storage Case, Multi-Color Labels

CNC Endmill & Bit Storage Case (Parametric, Multi-Color Labels)

A compact CNC bit storage / transport case with a sliding, labeled insert – replaces the usual chaos of individual plastic bit cases and keeps the full tool stock visible at a glance.

Key features

• Transport/storage case: tools stay seated and protected inside the box (good for storage + moving around).
• Sliding insert block: holes + grouped labels to organize bits by type/size/angle.
• Door with hinge + snap latch: simple printed hinge + pin/bolt, door snaps shut when closed.
• Multi-color labels (easy):
  • Column labels next to the holes
  • 2-line label on the door/front
    Labels/text are separate objects, so in the slicer you can simply assign a different color/material to those parts (no manual text painting).
• Fully parametric / customizable (FreeCAD): all main dimensions, counts, hole diameters, label strings, and door text are controlled via a spreadsheet (see screenshot).

Ready-to-print presets

Currently, there are 3 ready to print profiles:
See the screenshot “P1–P3” to understand what each version is for.

Each preset consists of 4 parts
 

Preset-1: 12x4 3.7mm Holes for End mills 0.8 to 5mm:

For Small End mills (3mm / 1⁄8" shank)

Preset-2: 10x4 3.7mm Holes for V-Bits 15 to 120 Degree:

For V-Bits for engraving (3mm / 1⁄8" shank)

Preset-3: 8x3 6.8mm Holes for End mills 3 to 8mm + misc

For Mixed / Larger Shanks (recommend manually drilling to larger diameter)

Need another preset?

Comment your grid + hole size + labels — if it’s useful for others I may add it.

Multi-color printing (labels)

The label/text parts are exported as separate objects.
In your slicer, just select the label/text object and assign a different color/material. No manual selection of letters needed.

Customization (FreeCAD)

Download Bit-Organizer_FreeCAD-Customization-Package.zip (contains the .FCStd + the font file).
Keep both files in the same folder so FreeCAD can find the font.

Steps:

1. Open the .FCStd in FreeCAD
2. Open spreadsheet param → edit the Active values column (or copy/paste a preset column)
3. Recompute
4. Export the 4 parts one by one as STL (Box, Block, Door, Bolt)

Print settings

• 0.4 mm nozzle
• 0.2 mm layer height (standard)
• No supports needed
• Brim recommended (especially for the box/bolt depending on your bed adhesion)
