Really wanted to have a access to a reliable 3D-printed cable tie that wasn't tiny. So I created this 8 inch standard cable tie.
Works really well and reliable for me. Haven't had any issues so far. If you apply enough force to the locking paul, you'll eventually bend the locking arm backwards and it'll be more of a loop and not a cable tie.
Used 2 cable ties in unison to secure a ribbon cable on my 3D-printer as it was awfully close to catching on the bed as it moved. (no I did not use it to secure a stepper motor haha)
One day I'll make a variation of this so that it is reusable without breaking a fingernail.
Be sure not to fold/crease the cable tie if you're using PLA or else it'll split into two parts.
