Title: OLED screen doesn't fit in case [solution]
Post by: asage on March 25, 2025, 12:57:43 PM
I printed out the OLED case from the GitHub repo (https://github.com/LowPowerLab/CurrentRanger/blob/master/CR_OLED.stl) and it's too tight to fit the screen into it.  Was there a new model OLED selected?  If so is there a newer STL I should be printing?

With each OLED batch the dimensions can be slightly different, so I adjust (usually enlarge) the STL by a fraction of percent in the slicer.
For instance the current OLED batch is printing the STL at 100.4% and it fits perfectly.
Even then some OLEDs have rough edges so I sand away the PCB Vscoring a bit to make them fit.
I did reupload the STL right now anyway (https://github.com/LowPowerLab/CurrentRanger), not sure how it was different but I may have adjusted it back a few years ago when I went from blue oleds to black ones. Give this a try, let me know how it works.

Awesome!  Thank you very much.  I will give it a try tonight.  Should have just thought to try that on my own, forgot you can easily scale models in the slicer.
