Also, I find scophony systems are very interesting. But probably quite hard to build. Especially without using a laser.
A 2 what ever system drum disk mirror idea gives you more flexibility ...as in a standard mirror drum will give you the screen size but you are again stuck as a Nipkow disk at that line rate ......where as change the speed of a 2 what ever system makes it multi system same as a electronic tv but limited to how fast you can drive it so made for your very multi system software .
I have made this and that with the old polygon mirror motor scrapped from laser printers .....lasers and mirrors are a problem but safe if you follow some safe procedures you can use a led if you want to view off the mirrors but i find that not to pleasant as a viewing screen .

Since you have a 3d printer much easier to make some thing nice such as Gregory and he's device.

Think this below would more be your thing
You might be more interested in Holtzman's monitor ,i have made 2 first version working below manual syncing touch off here .
The mistake i made on my second was the main drum plastic was to flexible a wobble at 60 line speed caused line wobble at 32 not to bad but got worse at increased line speed

..Maksim Holtzman is a much better constructor than me and he's monitor gave beautiful pictures as you see in the you tube videos went to 2 colour as well ...gives you an idea of screen size and why i like these over a Nipkow .
