I couldn't resist any longer, now the last piece is glued to the hull, I had to put a coat of paint on

Now it's starting to look like a Centurion.

next is the finishing of the back of the tank

Coming together nicely Alwyn, can’t wait to get these printing, I’ve a print running that should finish at midnight, I might just risk the wrath of her indoors & print them over night
Cheers

Top effort Alwyn, it's been an exciting journey seeing the iconic silhouette take shape. The finish line's in sight, so of course the question on everyone else's lips now is "what's next?". ;)

Thanks everyone for the good words, it's much appreciated. The satisfaction of seeing a tank emerging from a stack of styrene sheet and PLA filament is enormous and I'm sat here looking at the Chieftain and Centurion side by side on my WIP shelf and having a brief rest before finishing off the rear of the cent.

Image

I'm feeling a bit 'tanked out' at the minute, and I think I might return to some unfinished projects like the 1/10 scale Morris quad and 25 pounder gun, and the M19 Diamond T and trailer which are sitting on my shelves and pleading quietly.

Anyway onwards and upwards as the saying goes.
