It took a while, I couldn't build for a long time in a row, and besides, I'm very dubious about the flaps, despite the correct dimensions in SW I really don't get it right. I also had to demolish things, so first the rounded plates, they were too thin, so I replaced them with thicker ones, now it looks better
But yes, if we put the stuff together it is not neatly aligned, as was rightly pointed out
So, what do you do then.........................
Yep, we're just going to demolish
And then just align the components bit by bit
So this comes close
TIP: if you are going to scratch something, measure everything 2 times and check yourself 3 times, but accurate dimensional sketches
