That’s a great price considering the work and numerous prototypes involved!
I would be interested by the stl but I need to find a painter first
I have two tips I would like to share with you:
i didn’t see any display stand option, but I have noticed that it can save a lot of place by displaying the toys mid air on a flight stand. The most practical stand I have found is the Gundam / 1:12 figure display stands which have a plastic pin. They sell for 2-3$ each on aliexpress and can be found in any Gundam stores. And it is easy to design the hole or drill it.
Buy pins! I have bought hundreds of 1mm diameter pins in different lengths: 3mm, 5mm, 6mm, 8mm, 10mm. 12mm. And never regretted it. Each time I am running short of one size I can’t imagine myself to cut the pins, sand them smooth etc. So I just buy them over and over.
