QAV_R motor guard (with Dual material Print)

thingiverse

My custom remix of a motor guard for my QAV-R quadcopter frame is complete. In TinkerCad, I combined the guard from Sl33py Dog with mounting holes from meoster to create a single model. The mounts needed to be sturdy enough to withstand a crash, so I printed the entire guard using Ninjaflex. Unfortunately, the flexible material made it difficult to tighten the motor screws without pushing all the way through. To overcome this issue, I decided to print the guard in two parts: PLA for the bottom 2/3 of the mount and Ninjaflex for the rest. Using Meshmixer, I sliced the model accordingly, and then created G-code for both parts using ReplicatorG. Next, I merged the code into a single file. To achieve good prints with the Ninjaflex, I increased the temperature to 240 degrees, which caused it to ooze, but allowed me to get decent extrusion. However, at this temperature, I was unable to get good results, so I tried printing at 240 degrees and manually slowing down the print speed using the on-screen menu during printing. This resulted in a better print quality than expected, with excellent adhesion between the PLA and Ninjaflex.
