This is a holder to record with a phone objects magnified by a microscope.
This model will work with a 2.8mm eyepiece and a Mi 10 lite 5g. 
It can be adapted to any phone by modifying the holder and if needed it is possible to adapt it for smaller eyepieces.
To print this I used PolyTerra PLA+ with a 0.4mm nozzle. Supports are not needed for the barrel and are suggested for the base of the screw.

A small 3d printed catapult, the model already accounts for clearances.
It does require an elastic band and some assembly, you will need to glue/weld the arms to the base.
