Eachine Wizard X220 Propeller guard

I'm not a good pilot, so i needed some guards to protect my propellers ;)
Many online designs need a lot of supports and i don't like it because i see it as a waste.
There are designs that do not need supports because they remain flat with the motor mount. The downside is that these designs don't protect well the propellers because they are 2-3cm low.

My design is an hybrid, it prints flat without supports and the guards are bent afterwards with an heat-gun.
The "support" mounts under the LEDs under the motors, it uses the original motor screws. The "guard" have a dovetail tapered joint and thus is a simple press fit with no screws (and thus can be removed during transportation).

Why is the dovetail is so long?
Two reasons:
1. To avoid tinkering with the tolerance, if your printer is a little bit "sloppy" there is no problem
2. They work as legs to cushions vertical falls.
[If your printer is very precise, you can try and upscale the "guards" by a few percentage points to achieve a tight fit.]

How to bend the guards?
One possibility is to keep the bed warm after the print, hold down the external part and lift the shaft 4cm. This didn't work for me, but can be worth a shot if you don't have an heat-gun.
The best way is to use a heat gun (even better a rework station). Place the guard in a heat-resistant surface, put something on the external part to keep it down and flat. Heat up the little arms joints and lift the "shaft" about 4cm.
I guess that you can also use a lighter, but i don't recommend it [please don't burn yourself :)]

Why that "funny" arms shape?
The idea behind is to absorb the impacts without breaking the plastic, however too much bending can result in the propeller touching and thus breaking. For this reason there are three versions with increasing stiffness if you see this problem.
However, the design files are available in .STEP and .f3d format if you want to edit them.

Downsides?
1. Weight and added inertia.
2. Maybe an higher change of the drone to get stuck in trees

Any feedback is very much appreciated :)

I suggest a layer height of 0.2 on the support to make the connector a little bit smoother. The guard can be printed with 0.3+ layer height as the resolution is not super important.
I have printed both with 3 perimeters and 40% infill, but was just a guess and i haven't experimented much.
