This is a work derived from curiosity. I just wanted to know how it would be to juggle a printed devil stick. For those how do not yet know it, a devil stick is one of the lesser known objects for juggling, not as common as balls, clubs or diabolos. It is juggled by controlling it with two control sticks, that you hold in your hands.The great advantage of a printed stick over a normal stick made of wood is that it can be disassembled, if you need to stow it away for travel. The result of my juggling experiment: it is a bit heavy for my taste (250g) but juggles allright. I can perform all the tricks I normally do with it as well. And it doesn't need tape because of its fine surface structure.You will need to print one piece for the middle, two for the ends and two clamps. Additionally you will need a couple of M4 headless screws and a long thin staff made of wood (diameter 8mm). Printing takes ages if you use fine layers (approx. 8hrs for the long pieces) but does not pose difficulties, if you use PLA. To make it more mechanically robust I designed the pieces as hollow tubes and inserted a long and thin wooden stick (8mm diameter). The pieces are fixed to the staff with headless screws (M4). I cut the threads with a thread cutter, but this might not be necessary. For printig the pieces, I choose a high percentage for fill for the middel and a lower one for the end. However, that did not affect the printing much, because due to the geometry and size the pieces mainly consist of wall layers anyway. The dimensions of the fully assembled stick are: diameter in the middle: 15mm, diameter at the end 30mm, total length: 66cmAdvice: I would get the wooden staff first, test print a bit of one of the pieces and check if the staff fits into the hole of the piece.
