Never before in the history of Ebay has a such a small order been so difficult to complete. I ordered a set of stainless allen bolts almost two weeks ago, he sent cheap flat head bolts which are useless, and has since been either ignoring emails or telling me that he has problems. If they don't get here within a couple of days I will have to lodge a black mark against him, and order elsewhere.

In the meantime I have been sticking the various parts onto the hull, and reprinting all of the undercarriage to match the PzIII tracks. It all lines up, so in theory it should run very nicely. It could do with longer springs, but I can work around that.

The only thing left to design is all of the racking, boxes and brackets in the crew area, and tow hooks etc.

Praise be, the bolts arrived today, so I attached all of the suspension arms, road wheels, idlers and both tracks. It's starting to look the part now.

Wibbly a true testament to all your hard work and dedication. Looks excellent I'm amazed how your design goes from a thought at the museum to a an actual running machine.

You are not the only one.....

The new printer is a Creality CR-10. Out of all of the printers out there it is the one that none of the You Tube reviewers have criticised, it has a large print bed, is as solid as a rock, and comes pre-assembled, just two parts to bolt together. It's not the cheapest, but Alibaba is where all of the bargains are. It's a rep-rap printer, so made from common parts, so no problem with spares in the future.

Nice one, Rob. I spent last weekend researching different entry-level printers based on the list of recommendations you gave me, and the CR-10 was what I'd decided on too. I need to clear my existing projects and free up some funds, and then I'll be looking to get one in the coming months too. Prepare to have your brains picked.

As I mentioned in the 3D printer thread, I ordered one, opened the box, and had it up and running within an hour. The print quality is 'very' good. I printed some triangular brackets for my Delta printer. These are 60 degree brackets, and have to be a friction fit on 2020 alloy extrusions, and have numerous holes and mouldings for screws etc. They all printed identically, and were a perfect fit. No adjustments to the printer at all.

One 15 hour print later, and I have a perfectly fitting one piece interior.

Glad to see you've got everything up and running Rob, it looks like the CR10 has already paid for itself with that print. I'd be interested to see some close-up photos to see the quality of the print, the treadplate detail on the floor looks great in the video.

It was the treadplate that increased the print time dramatically, because it was printed vertically the printer had to deposit one tiny amount of filament across each strand. The accuracy of doing that so neatly is amazing. The matrix is only 0.25mm in diameter?

It's difficult to take pics that show how smooth the surfaces are, although lines are visible the surfaces are all glassy smooth. I could get them even smoother if I downloaded the very latest version of Cura as it has a top surface smoothing option.

On the home run, still not got around to the interior though. Thought I would paint it before doing that so that I don't have problems getting at some surfaces.
