hello i designed this box for a tuner shop but it is a box you can open it from here and for that we need a square sheet of paper the crease pattern is very simple we start by dividing by half but only pinching here and just the same now we open up and we fold the cup a couple of fold in this way and open up rotate and repeat now it's time to complete the half marks up to the fold lines and again so it's almost a grid of four by four but we have the center almost straight so now we have to adjust a little bit more we take this corner to here but we squeeze or crease only from here to the left and i'll do it again from here and third time and the last time so this will be the base of the box and now we have to finish the processing at this square you have one diagonal we'll add the other one like this so it's one two three and four okay this is it just to show you the crease pattern in a bit more visual way this is what we have the green part it's the grid the red one is the two creases we have done in four directions and now we are ready for the collapse we first start with this full line we just fold it as it is and down now notice here it's the end of this diagonal and this corner is going to meet this point so it's going to be like this and now we want to go with this corner just to meet the same spot which is here so in order to do that we have to twist this whole line and now this corner wants to to get here so we fold this whole time and then here and now this corner wants to get here so we hold this whole time and we are finished now all we have to do is enforcing the pieces and make sure that here you have valleys but without any crease line i think it's better this way and this is the box thank you for watching
