Edit (May 18th 2024)

A small hint for Prusa Slicer users: Turn off Arachne Perimeter Generator in Prusa Slicer. It might fuse your model at some points. (thanks to @mrkthmn_320114 for mentioning. Check the comments for more information.)

I wanted to make a Double_Desert_Eagle Add-On for Flexi-Rex, 

[https://www.printables.com/de/model/708319-double-desert-eagle-for-flexi-rex](https://www.printables.com/de/model/708319-double-desert-eagle-for-flexi-rex)

but the model i had was too limp. Have fun with it.

Edit (Jan. 20 2024) - I added some slots for adding perimeters in Prusa Slicer, to give his lower body more weight.
