There are two versions, the first version is standard and can be cut to fit smaller printers if needeed ( in slicer cut recommended )
The second version is modified to fit Bambu P1 and X1 or printers with the sane print volume without cutting or support . Note (This is the one I recommend if it fits in your printer ,the surface finish is better with this print orientation.)
There is a tracksaw track compatible router base plate that fits in this packout insert fond here

Print settings recommend
Wall loops. 2
Infill.
5% to 10% ( I found 7% grid to be the best for the V2 1P model )
Filament.
PETG , PCTG , PLA*. * pla may not be the best if the box will be in the sun. ( heat reasons )
Other. use only 4mm brim on V2 1P model to make it fit on the build plate.
The author marked this model as their own original creation.
