Modified stand for 3D Printy's Barrel Puzzle

thingiverse

I love the barrel puzzle from 3D Printy, but wanted the key to be more hidden, so I modified the stand to replace one of the crossbars with a long version of the key. I needed a fair bit of force to crack the bolt part of the puzzle loose at first, so you would need a bigger/stronger key to do that, but now it is easy to turn with just the shaft of the key. If yours is a bit stiffer, then maybe this won't work for you. The gaps are quite tight (I just had to trim the tiniest bit of elephant's foot to get the key to slide in nicely), so if you struggle, I guess you could just print the key a tiny bit smaller (although I haven't tested this!).
