lay flat as much as possible, I used a brim to hold it down but as you can see it did curl 1 side but didn't do it the second time so meh, green stuff to the rescue. This is a work in progress it may require scaling up a little bit. that's up to you. I have not got any side weapons to print so using some off other models. This is approx the size or a rhino transport vehicle so may not be accurately sized to anything else it may be a proxy for. hope you like, I have grown quite fond of mine.
