Ice Lock+++ (2-/3-/4-way) with built-In D-ring

thingiverse

Human: Remix of Ice Lock ++ by trapfox adds 1 or 2 tie-off holes to the base. The original works great, but I wanted an extra point or two for added security. You'll still need to download trapfox's models to get the key that fits these bases perfectly. EDIT: I've included D-ring models for easy clipping using a snap hook. No supports are needed; I've added a small support that's easy to remove with pliers. 2nd EDIT: I've uploaded @trapfox's key STL file for completeness, borrowed from his Ice Lock ++ Thing. This remix is a variation of the original. 3rd EDIT: @trapfox gave me permission to include his original body STL file (nIceLockBody.STL). Choose between this ice lock or the original; both are included for your convenience.
