Here is the Large Red Back Spider model. I don't usually do anything Halloween-related (it simply isn't in my wheelhouse), but this was a request from a longtime follower. There are two basic versions: a two-part version where the body and the red marking can be printed separately, and a two-color single-part version. If you print the two-part version, I recommend lightly sanding the edges of the red mark before adding a touch of glue to insert it into the recess made for it. You can scale it up or down as long as you keep the two parts to the same scale. I have also added an STL file for the two-part version. This can be found under the Download STL/CAD Files section. I have included a free commercial license for those who wish to sell their prints.
