Pros: Great model, easy to print. Nice details and looks to scale. Designer was quick to respond to an initial enhancement but see "Cons". Cons: No option for printing a front glass insert so you can show the crew like the original model retail model. I initially reached out to designer requesting this upgrade and was willing to pay extra. He responded to wait a few days, which I gladly did. Followed up two weeks later and no response. Followed up a few times after again and after over a month now, it is apparent he has no intent to respond. Seems like a reasonable request/upgrade but I guess not. Overall: If you're looking for a proxy for the discontinued model that was sold retail, this is a great substitution. Just don't expect to display the crew unless you want to print the part without the option to print the glass in a clear resin or filament. If you have wish to have any enhancements such as maybe adding magnets to allow you to hold the two halves of the A-A5 together for future enhancements, don't expect a response.
