I sliced up your hi poly model and its on the print bed now... I have a feeling looking at it thats its a tad on the big side so may need to print it again. I can only print in ABS plastic at 0.4mm vertical density, and its probably a 10+ hour print run.
I can post pictures when its done but dont want to de-rail your thread. let me know if thats ok.
Also since you went to all the trouble of making this model, which is actually pretty good btw (most stuff I get from is far from solid) if you do have problems getting it printed Im happy to work something out if you just want to pay for consumables and postage
