Thug Frames FooFighter - Prop Guards (65mm)
Description
I wanted a way to tame the FooFighter a little for indoor stuff. So I made these in OpenSCAD. The script will work for any size true X frame just with a few changes to variables. It is printed flat with minimal supports(only the outer ring needs support for where it connects to the next ring). The multi-part construction helps put the layers in a direction that gives strength to the whole construction. It also means that any part can be swapped out if it gets damaged or broken without having to replace a whole guard. The joints are profiled to aid in assembly, and are designed to just take a drop of super glue to hold them in place. The guards then join to each other with either M2 screws(taping the plastic) or some 1.75mm filament used like a rivet. I printed them in NinjaTek Armadillo 75D TPU. If you haven't already tried Armadillo then I highly recommend you give it a go. It is really rigid but has some flex so is not as brittle as other harder plastics. I wouldn't recommend a 95-98A TPU as it will way to flexible, at the least I would print them in PETG so they last for a while. The attached STLs are for 65mm props with a prop line at about 17mm from the base plate with a few mm clearance of the props. They weigh 5g each and with the joining M2 screws a full set weighs in at 22g. If you would like the OpenSCAD file or for me to upload a different size/spec STLs then just leave a comment.
