my weakest point is taking a good pictures , need to find someone to teach that ,of course taking a professional pictures for your item will show how great it look that why I use BBQ
For 3D CNC I believe my speargun not yet reach to the optimum shape , still modification even small details is very important ,in this one band elevator was not done as I want and line guide need to be shifted few millimeter near the spear , this not affect the performance but affect shape ,when I make the perfect gun I'll go for 3D scanning ,today catch was nice but still rubber not giving me the enough power for long shot I need to either put another one or just go back to traditional 16 mm rubber
