RaspberryPI Armor Velcro mount

The Qidi X-Max has enough free space in the electronics "compartment" to mount a RaspberryPi. But it has to be mounted upside down - something which can be done rather easily with self-adhesive Velcro tape. This has the benefit of being able to easily reach the TTL pins (and also the touchscreen). But since the electronics are not really isolated from the printing chamber, it can get really hot in there and can cause some overheating problems in a standard RaspberryPi case. Luckily, the temperatures in the chamber are still lower than the temperatures the RPi reached - so only a larger heat sinks + active fans are required.

A solution here seems to be the GeeekPi Raspberry PI 4B Armor Case with Double Fan. But its heat sink design makes it hard to actually use self-adhesive Velcro tape on it. Something with a flat surface is needed for the tape. It is also important leave some space between the "flat surface" and the bottom of the heatsink to ensure that it can still do its job.
