I tried to make flexible stick-man that one could stick together with magnets. The 5mm versions allow bending. The 9mm ones are stackable but do not bend much. If you want to customize OpenSCAD files, have a look at the magnet parameters: If using TPE, make the hole smaller, e.g. for a 5mm magnet use 4.4 In addition, you can add a bottleneck on top of the hole (magnetextra* parameters) and either keep the same length of the hole or make it longer (magnet in this case will be "inside") Ninjaflex doesn't glue well, so I really suggest to make the hole as small as possible. Use a stacked stick of magnets to force them in. In addition you can add glue, e.g. I tried Pritt extra strong (wait a few hours before use). Anyhow, reducing the hole size and adding a bottle neck is more efficient than using glue. TPEs like Ninja Flex should be printed slowly, e.g. 15mm/sec for first layer and 25mm/sec for all the rest. Using a bigger than 0.35 nozzle also would be a good idea (the sticks in the picture are made with a 0.35 one). To insert the magnets, take a stack of 8 or more magnets (you get more force like that and it will be more likely that you get the right direction). You also can stick a magnet into the head and the heart. This allows for more funky constructions. Then you have to take a decision about the direction (polarity of the magnets). For most stickman I printed, I always use the same direction, i.e. the hands of stickman A would stick to the feet of stickman B. Make sure to test the right direction before forcing the magnet into its hole ....
