Happy new year to all!
Being in the Norwegian wood for a while, I`m out!
After mixed experience with etching, I got interested in 3D printing. This have resulted in a few new parts for my Rena 1900 project: steam NG loco NSB type IV in N finescale 1:160. But designing for 3D printing have given me some frustrations also. I use Sketchup for designing the 3D files. For a while I have struggled with a drawing comprising the cab and sidetanks. I plan to print it in high detail steel or brass for weight. So far I have not been able to refine the drawing into STL format which is required by the printing companies. I now think all the tiny boltheads may be the problem. But I have succeded to have some other parts 3D printed. Its the splitframes printed in brass and a soldering fixture for holding etched parts together while soldering. This as an alternative for 3D printing the cab and sidetanks. The turned brass boiler in the picture is ok, but I like to try 3D printing also this. Afterall, I need several of those locos. The motor is a 5mm Ø pagermotor that I was lucky to obtain from China. It slides snugly into the boiler. The picture shows the leads popping out of the boiler tube in the front.
