FractMod- Print in Place Keyhole Marking Tool Case

****Revision Notes at The Bottom****

KMT Case – Print-in-Place Storage for the Keyhole Marking Tool

This fully print-in-place case is designed specifically for my Keyhole Marking Tool (KMT) and provides compact, protective storage for your shop, toolbox, or drawer.

The case prints on a single plate and securely holds three Keyhole Marking Tools. After printing, simply slide the latch into place, install the spring behind it, and you’re done. Since most projects only require two tools, you’ll always have a spare ready no digging, no loose parts, no lost tools.

This case is intended for use with the Keyhole Marking Tool (KMT).

Print Details

• Fully print-in-place hinged case
• Prints on one plate
• Holds 3 Keyhole Marking Tools
• Spring and detent latch print separately and are installed after printing
• No supports required

This design delivers the convenience of a print-in-place case while keeping the spring action crisp, reliable, and durable.

Why Three Tools?

Most keyhole-mounted items use two fasteners. By storing three tools, this case ensures:

• You always have a backup
• You can keep a matched set together

• You’re never stuck mid-project

   

Simple, practical, and built for real use.

Print it. Store it. Always have a spare.

4/16/2026- 

Thanks to user feedback the latch design has been modified. Geometry was changed to rely less on tolerances creating a latch which is easier to reliably print. All print profiles have been updated with the new design. 

A 3rd print profile was added to include @netwalker 's graphic design.
