PwnCNC 20 Numbered CNC ATC Tool Cups - STL + STEP Digital Kit

Organize your CNC tooling like a pro with the PwnCNC 20 Numbered CNC ATC Tool Cups Digital Kit.

This premium digital file kit includes a complete print-your-own tool cup system designed to help CNC owners, makers, and small shops keep toolholders organized, visible, and easy to match with a controller, ATC setup, or tool table.

Each tool cup is individually numbered 1 through 20, making it easy to assign physical tool positions to your CNC workflow. Whether you are organizing ISO20-style toolholders, setting up an ATC machine, or simply cleaning up your CNC workspace, these files help create a more professional and easier-to-follow tooling layout.

Standalone Purchase or Digital Library Access

This file kit can be purchased as a standalone digital download, or accessed through the PwnCNC Digital Library while your membership is active.

Standalone purchase gives you access to this specific digital kit. PwnCNC Digital Library members can access this kit as part of the eligible member library while subscribed, along with other eligible digital file kits added over time.

Premium Digital Kit - Includes STEP Files

This is not just a basic STL download. This kit includes both printable STL files and editable STEP files, making it one of the most complete digital file releases from PwnCNC.

The included STEP files are a major addition for customers who want more control over their prints, need to make personal-use modifications, or want to adapt the design for their own shop setup. STEP files provide more flexibility than STL files and are especially useful for experienced makers, CNC users, and CAD-capable customers.

Because STEP files allow for customer-side modification, the included license also explains how customer-submitted improvements are handled. You may modify the STEP files for your own personal use. If you choose to send PwnCNC your modified version, CAD change, improvement idea, or suggestion, you give PwnCNC permission to use that feedback or modification in future product updates without payment, royalty, approval, or additional permission.

Designed for Functional Shop Use

These parts were designed for real workshop use, not just display. They are intended for makers and CNC owners who want a clean, reliable, and professional-looking tool organization system they can print themselves.

Recommended materials include PETG, PC-PBT, ASA, ABS, PLA+, or other suitable filaments depending on your printer and shop environment. For stronger CNC shop parts, PwnCNC commonly recommends PETG or PC-PBT with higher wall counts and increased infill. A strength recommendation guide is included to help you choose appropriate print settings.

Magnetic Base Assembly

The included MagBase and TPU Spacer allow the printed tool cups to be assembled into a magnetic tool cup system. The MagBase and Tool Cup are designed for 6mm x 4mm N52 neodymium magnets, which are available separately from PwnCNC.

Suggested hardware per assembled cup:

• 8x 6mm x 4mm N52 neodymium magnets
• 4x M4 x 14mm flat head / countersunk screws

Please review the included Assembly Guide and Hardware List before printing or assembling.

Recommended Use

• CNC ATC tool organization
• Toolholder storage
