Here is a little magnifier for small-to-read OLED or LCD screens, this is for lenses that approximately 1" by 0.5" big, but of course you may need to adjust! NOTE: you still need to buy a magnifying lens, these can be had in bulk for cheap, or you can use any magnifying lens and cut to shape! Most lenses on the market are now plastic, so you can easily trim them down with a Dremel or other rotary tool. Be careful, you only have 10 fingers!
As you can see, I use this for small Eurorack screens. The model as is fits perfect into the wonderful clock/trigger module called Gravity by Sitka Instruments -check them out if you don't know them yet!. The magnifier works perfect and it will make you feel like you are watching an old tube television again! It magnifies about 3x, but you can increase this simply by extending the cone at the bottom of the holder - this can be done in TinkerCad or other software program fairly easily.
And this was a rough draft of a model, so if any engineers can thinks of ways to improve this or add to it, please REMIX away!
This was printed with PLA but can be done in PETG or any other material, no supports needed. I did find I got better results when I printer at 0.1 mm layers, just to make sure the cone is shaped nice. but the default for most printer is 0.2 mm, and I have printed with that as well, you just get a little more stranding.
The author marked this model as their own original creation.
