Proteus (modified with control surfaces reinforced)

This is rework of the wonderful Proteus U-91035 by guydebored. I work with HP industrial 3D printers that use powdered nylon built up in layers so no support is ever needed. I can test print literally anything which is why I don't need to have models sliced up for the home printers. I was excited to find his file for the Proteus. When I printed it, unfortunately, the control surfaces quickly broke off because they are attached by the accurately depicted pivot shafts. I am just learning to use Fusion 360 and placed in "slabs" to better anchor the control surfaces. I haven't had a chance to 3D print yet, by my HP slicer shows no errors with the STL file. Unfortunately, I don't have the expertise to cut this in half (yet). guydebored recommends to print with support so that is all the advice I can offer.

Edit- Uploaded a lower poly STL, much smaller file size.
