Wall bracket / mount / hanger for Xiaomi M365 Scooter

What's this?

This is my custom wallholder for a Xiaomi Mi M365 Scooter, including space for the powersupply. I wanted to create a design which doesn't look too bad, is able to securely hold the scooter and also doesn't need a ton of filament, so it shouldn't be too large.

The design consists of 4 parts - two wallpieces, which get screwed into the wall with two 4,5mm countersunk screws and two “arms”, which slide over the wallpieces, hiding the screws. The following GIF should make clear how it works.

Here's a picture of two scooters attached to a wall with them.

They are holding up quite nice for me.
 

Printing the parts:

It is very important to use durable filament and enough infill at the right places. That means no PLA. Also, the print-orientation matters a lot, see below.

I used ASA-X CF from Spectrum Filaments, but “normal” ASA should also work - maybe even PETG?

It's important to get the high layer-adhesion, because they will otherwise fail by splitting apart from the tension.

As this is mission-critical, I'll visualize what I mean by adding some GIFs, but I also will share a PrusaSlicer Project with the correct paramters.

The wallpieces:

The wallpieces need to have 100% infill where they're screwed into the wall and at the slot-part. The slot also needs support, I used organic ones because they work great here.
The part where the power-supply rests on doesn't need to be particulary sturdy, so I used 20% infill there to save some filament.

Also, the orientation is important - Yes, I know, I could have printed it without supports by laying it on its wall-side, but this will not work because the layers need to be oriented like in the GIF or the weight of the scooter will break it.
If printed laying on its back, all the forces will pull on one layer, which the layer-adhesion cannot sustain.

The arms:

The arms need to be extra-sturdy in the area around the slot - again, this is extemely important and they will not hold when doing it wrong!

Personally, I printed the whole part with 100% infill, 3 perimeters and 0.2mm layer-height.

This makes it extremely strong, but after some testing and simulations in Fusion 360 I think that this is not neccessary.
The main stress concentrates around the wall-slot and the U-shaped slot for the scooter.

That's why you should be able to get away with 100% infill around the wall-slot, 30-40% in the middle and 50% at the scooter-slot.

I'll provide two different PrusaSlicer Projects, one with 100% infill and one with the minimum amount I think will work.

I'd love some feedback if someone tries the filament-saver-edition! I'd test them myself, but currently I don't need anymore holders.
