Wera Toolcheck ULTIMATE PRO (Zyklop Speed 1/4")

UPDATE 28.02.2026

Added a print profile for a more loose fit for the bits.

____________________________________________________

The Wera Tool-Check Ultimate PRO is a fully redesigned, 3D-printing–optimized upgrade of the original Wera Tool-Check Plus, created for users who want maximum functionality, modularity, and customization in a compact tool system.

This model replaces the standard mini ratchet with a full-size Wera Zyklop Speed 1/4" ratchet, significantly improving ergonomics, torque handling, and usability, while maintaining the iconic Tool-Check layout. In the PRO version you still have a place to put the Mini-Ratchet of the original toolkit as well as an extension 75mm for the Zyklop Ratchet.

The left side of the Tool-Check Ultimate is fully accessible for all modules, as it uses the negative slide-in connector geometry. This allows modules to be inserted from either side and enables the use of the Wera modular hinge on the left side as well.

With this update, the Tool-Check Ultimate can now be folded on both sides, matching the flexibility of the Wera modular system while retaining full compatibility with custom and OEM modules.

I'd like to shout out @SimonLeib for new ideas and testing out different fits. Some tolerances in this version are a little tighter and some a little looser.
