lithophane frame with built in lithophane storage

I found that the Bambu Labs designed lithophane frame while nice on paper had some issues with stability and also could not store extra lithophane slabs if you had more than one. I also found sometimes the gap where you slide in the LED board from Bambu labs was sometimes tight and caused me to break a few LED's.

My frame has the following major differences and mostly is rebuilt.

1 - It has a solid stand while designed for landscape layout it can be used for portrait if needed.

2 - The access slot where you slide the Bambu LED board has been slightly increased to allow easier and less risk free install and once installed is still snug.

3 - The built in stand has slots to allow 3 extra lithophanes to be stored allowing the user to swap them easily.

I have provided the STEP file and the 3mf file you will need the following settings to best print

Filament type: PlA/PTEG though I printed in PLA
Wall loops: 5
Top shell layers: 5
Bottom shell layers: 5
Sparse infill density: 80%
Support: tree (auto) 

I also printed with support PLA to act as interface though I printed in a way to try and reduce as much support as needed.

I used the original purely to get measurements and dimensions for the lithophane part where you install the LED board sold by Bambu labs.

Besides the frame bit been mostly similar the rear is original solid stand design with slots to hold 3 lithophane slabs.
