Calibrated Spring System

The Massive Novelties Calibrated Spring System has gotten an upgrade!

The Calibrated Spring System can be added to any existing MN Product, but is mainly geared towards being an upgrade for DIY and 1.0 owners.

The new spring system can now measure up to 20 pounds of tension! The 3D printed casing has been updated to include small guides to keep the crossbar in line with the spring system. This makes the process of increasing tension both easier to track and less likely to snag. The measurements have been etched into the casing preventing them from wearing off. 

Kit includes the springs and tubes assembly. You will use your old crossbar and hook.
