D/DA Diesel Loco - 3D Printed

The first test prints have arrived for both the D and DA class diesels.  Both models have now been assembled and are running, including DCC and sound (Tsunami EMD645 non-turbo).

The model is designed to use a Hollywood Foundry mechanism, which can be supplied with the correct axle spacing.  Hollywood Foundry don't offer the correct size (15.7 mm) wheels in their normal range, so the wheels are from Northyard but Hollywood Foundry can fit them to their bogies during the normal assembly process at no extra cost, other than the cost of buying the wheels.  

The cosmetic bogie sideframes will be 3D printed as well.  

There is more info on the Marbelup Models blog.

Test print of D class fuel tank, with 7 layers of lead sheet added.
Weight: 166 grams.  Top 2 layers have central gap to clear motor.
