There are 2 approaches, which seem to be used by hackers:
The birdbrain method: https://youtu.be/mm2ZiJNfISs?si=2QqST28nyiQPh9w5 --> PWM fan motor based
or sth. based on https://hackaday.io/project/192036-diy-spin-coater

My personal preference is to the 2nd one.
Cutting off plastic with a knife and using some pwm-fan looked hacky.
Furthermore, an approach with brushless motors makes it possible to "upgrade" the device, if we need sth. with more punch.

We can get at least 1 of the recommended engines from banggood:
https://de.banggood.com/Racerstar-BA2216-880KV-or-1100KV-or-1250KV-or-1400KV-or-1800KV-2-4S-Brushless-Motor-For-Fixed-Wing-RC-Airplane-FPV-Racing-Drone-p-1798968.html?akmClientCountry=DE&cur_warehouse=CN&ID=47995557529&rmmds=search&a=1751395804.2277
We can go even cheaper with aliexpress:
https://de.aliexpress.com/item/4000589355217.html
Then we even have an ESC
