The model uses some of the parts used in the Dummy 13 Frame, so assembly is similar. Print with supports and maybe brim, in PLA or PETG, preferably PETG. I may edit this model later to lessen the number of supports needed, or to make the joints work better.
Update: please use version 2, it is spaced better and has a modification to make the joints fit slightly easier.
The author marked this model as their own original creation.
