Success!!!
Testing the Arduino MIDI controller, attached to the Tiny LD with crocodile clamps:

Removing everything but the glued-on touch screen:

Marking how much space I have, and later also where to drill, on some sticky paper:

Pre-drilling the top panel with a 2.5mm metal drill bit worked super well:

Opened up the holes with a 5.5mm and 6.5mm drill bit. The pots actually needed a 7mm hole, which I didn‘t have a bit for, but I could expand them with the 6.5mm one:

It all fits:

Testing the Arduino MIDI Controller again. Still all good

Cramming everything into the case. The Arduino sits in the lower left corner and is held in place with a piece of 3M Dual Lock (my favorite synthesizer adhesive):

Added some potentiometer caps:

So now I have two switches, each sending either a CC value of 0 or 127 (which I can scale and invert in the Tiny LD), three pots and a light-dependent resistor (LDR). Switching the first switch up will make the LDR hold its current value, which I always wanted to try. From testing it now, it‘s indeed a cool feature, because you can shine a light on the LDR or cover it with your hand and if you want to do something else, you can just hold a nice sounding LDR value, without it jumping back to zero or the maximum again.
I also added a random CC generator for each control in a different CC# range. So flicking switch 1, for example, will set CC#20 high or low, but also generate a random value on CC#40. Same for the pots and the LDR. So in total I have twelve CC# for funky, manual modulation.
So far so good though! I will post some video jams with that setup of course. I must also find
a good way to disable my mod next, because right now it‘s soldered to the MIDI In port of the Tiny LD internally, so I can‘t connect an external MIDI source.
EDIT: Formatting, typos, all electronics working fine now, added random CC generator to the Arduino code.
