JJ-CCR Hud protector

My Hud did broken while transporting the JJ
So I design this little box to Store and protect the HUD and attach it to the JJ when transporting

For the fun I did design it in 1 piece no additional screw. it print without support
I print it with PoliMaker Polycarbonate (PC-Max) for maximum strong.
Actually the prototype where print in PETG and it yet very strong

I add the Fusion360 file if you want to improve this

UPDATE:
3mm thickness did broken.
So I change the design for 5mm
v15 -> 3mm
v20 -> 5mm

UPDATE 2: (2020-05-29)
I add some guide to avoid HUD moving inside the box and button be pressed . This avoid HUD to turn on unexpectedly
v25 -> 5mm with HUD blocker
