Juice Box Holder with Handles

I designed a juice box holder to help prevent my kids from squeezing the juice everywhere and the tantrum that ensues thereafter. 
 
Added my kids names after making the original model, but should be much easier with PrusaSlicer 2.6’s text tool.  

Internal dimensions are 51mmX39mmX77mm

3mm thick

When I did the lettering, I had it set to 1.5mm deep
 

Printed on an Ender 3 V2 

LH 0.2

4 perimeters (otherwise at 3 perimeters the gap for infill is very small and results in a lot of unnecessary zig zagging movements when laying infill down)

15% infill

supports : yes
