Morgenstern

“Have - have you got an appointment?' he said. 'I don't know,' said Carrot. 'Have we got an appointment?' 'I've got an iron ball with spikes on,' Nobby volunteered. 'That's a morningstar, Nobby.' ― Terry Pratchett, Men at Arms Really like the medieval weapon. I've printed it with ABS. In order to minimize support I divided the morningstar ball into two halves and each chain ring as well. I used ABS juice (ABS + acetone) to glue the pieces together and it works great. So yo just need to print 2 pieces of morgenstern_half.stl and 12_half_ring.stl (6 chain rings). You don't need to use support for half_rings (but you need it for the main part to support the spikes). You can use chain.stl to print half of the chain ring. I also included the file morgenstern.stl and chain.stl which allows you to print the main part and the chain. But I don't recommend to use it because removing support ruins everything. But maybe you have a nice two-head extruder and soluble support. Beware:
