Remix of Thumb cuff WITHOUT KEY (no vise required)
Remix of thumbcuff from https://www.thingiverse.com/thing:4769354 but without the key and better spring arms, SO YOU DON'T NEED TO SOURCE A SPRING OR PRINT A KEY! All the convenience of a 3d print, only abit of the hassle of putting it all together.
Note: it should not require a vise to clamp as dimensions have been set to space them further apart and allow for some play in the gaps, so it is a bit more flimsy than the original in terms of breaking the whole thing apart, but it still holds together pretty well. This also allows you to open it back up for repairs if needed.
Please print both RatchetA and RatchetB as they have they own respective levers. The assembly should be similar to the original.
This version of the thumbcuff also does not require a key, allowing you to remove it easily in case of emergencies. Just remember to face the lock away from yourself so you can use your index fingers to open it. Due to the lack of a key, it also prevents the spring arm from being overstrained, so it should last much longer before needing a replacement.
Please remember that this is meant to be a non load-bearing toy and that you should always use it with safety in mind.
Do pop me a message if the pieces don't fit as expected. I might probably take ages to reply though.
