The model looks very great and his screen accurate.
I scaled it down so that the overall figurine measured 13 cm high (the scale is 1/16)
I printed it using a resin 3d printed, with separated parts. Gluing the parts togethers was easy but there was some gaps (even after a bit of sanding). For example, between the right arm and the chest, or between the chest and the legs. So I would recommend, if you can, to print it in one piece (even though it's harder to paint). I didn't print in in one piece because the one piece version comes with the stand, and I like to have my model free from their stand so... Painted using an airbrush, with Vallejo paints.
I also printed separated helmets : really cool ! The different versions of helmets is very much appreciated.
