! I threw this together in like 5 minutes, do not be surprised if it does not assemble correctly !
For assembly instructions, just follow the normal Dummy 13 assembly guides, of course print 2 extra arms but no major changes for assembly.

The author remixed this model.
Modified the chest frame so you can put 4 arms on
