Thingiverse admins!
Krank up the servers instead of messing with the design again and again.

REVERT to the previous design.

Update:
Picture: the train, harvester with the trailer attached
It needs still some tuning, the covers and a full size cabine.
But, man. it was a long way to come to this point.

New parts:
-simplyfied trailer parts based on a rectangular bar instead of a circular rod

• bar combined with supports and lug (bar length:224mm)
• toolbox for rectangular bar

-small parts for making the trailer assembly (see the 5x part numbers)
It utilizes a circular round rod (diameter 6mm)
The wheels on the trailer are the same as on the rear of the harvester/combine.

ZIP-archive with pictures of the reel trailer

Latest new parts:
-beveled drivers roof (hollowed)
-simple drivers roof (hollowed)
-simple drivers roof (solid)
-rear wheels with the red rims.
-big wheels with the red rims.
-front wheel rim 40/50mm
-front tires for wheel rim 40/50mm
.

New parts.
The reel (rotary cutter tool) rods (diameter 3mm) holder plates:
-intermediate (take 2 pieces)
-endplate through the hole (take 2 pieces)
or
-endplate cap (take 2 pieces)

Choose from the endplates, depending on the end tips of the rods you have.
I have used sticks from Mikado game, with peak tips.
Have cut off a bit from the tips.
If you have flat ends you could push them trough the holes.
For mechanical strength with no glue I have used both plate types,stacked in series.

New parts:
smaller tail lights parts (for those how find the 12mm diameter lights looking clunky)
-tail light bar with lights 8mm
-tail light bar flat 7.5mm (easier fit in the channel)
-tail light cap 8x7mm
-tail light bar with lights 12mm
-tail light bar flat 8mm
-tail light cap 12x7mm
-front axle 82mm for big wheels
-rear axle 55x21x8mm for wheels 31-34mm
-mirrored big wheel
-simplified feeder V1-3
-base part 3 (with hollowed structur) inside for easier printing
Take care when generating the needed supports. Do not waste time and filament by printing support inside of the part.
A group of 4 mount holes has shifted to unwanted position. Not a big deal.
The holes on the base1 part make the pilot holes for drilling something new.
.
Do not look close up at the printed parts.
Printed out at low speed of no more than 50mm/second it should look much better.
Made on the new printer (Sovol 01), see below.

While waiting for the next part I made this:

The making of the thing goes on.
But you know. The layers make the steps/stages.
Had set the top and bottom layers to 3 each.
This should allow some smoothing by sanding down the stairs.
Or doing the pant job with the filler and sanding repeatedly many times.

-New part:
base part(1-2) combined with head lights
It merges base part 1 and 2 into one, it has much material cut off, less printing needed
Hope the side walls will prevent bowing of the plate.
Nevertheless it takes a long time to print it out.
.
-Have printed base1 V1-2 part relatively ok,
except from layer shift caused by wrong filament change midways,
it has shown a little bowing after taking it from the bed.
.
-New part:
Base part1 V1-3, it has doubled the thickness (10mm, with headlights)
.
Attention please: the biggest part x*y direction size is 215x81mm.
This might not fit smaller printers work area dimensions.
.
slightly dimensionally changed V1-2 parts with mount holes added
Base1
Base2
Base3 with groove for tail lights bar
Kornbunker
Dreschkasten

This is the upcoming E512 harvester/combine, the Sandmann TV edition.

For the original white/blue color schema see the pictures of the operational machine.
Many can be seen in action on YouTube. Just search for E512.

By start making the printed parts this is the begin of a temporarily made and hopefully frequently updated worklog.
Will be cleaned up when finished.

See the other things I have designed and made.
It has the growing fleet of mobiles I have made.
Given the little Sandmann, the GdR made TV hero , lovely alltime favorit of children since 60 years.

This is in early stage.
This time I could accept a bit of glueing when needed.
As with most of my mobiles, small juntions will be made by using 2mm diameter tooth picks.
See the drivers work place.
The part without the seat, no integrated wheel guide, no integrated control box has a few small holes.
Same with the corresponding parts.

The feeder and the cutter holder assembly have those pins as well.
Those pins are used on the mount of the rotary cutter as well.
But to make it safe a screw of 3mm diameter will be applied as well.

The design follows the original "E512 Vollerntemaschine" (harvester/combine).
Made by the company "Fortschritt" located in Saxonia / GdR starting 1968.
https://de.wikipedia.org/wiki/Fortschritt_E_512

Same as the ZT-300 tractor and the W50 truck the trusty workhorse of the GdR farmers. Many are still in service, now in the eastern regions of the BUNDESREPUBLIK.
Exported to many countries all over the world.

Some farmers and fans not only use them for harvesting but having much fun on meetings.
The picture has the E512 whipped by crazy Czech farmers/fans on an annualy held meeting.

Guess what, the cars and tools made in the GdR do not need expansive crippled fucking proprietary copyrighted spare parts protected by IP claims. (John Deer and alike).

It just needs a few very simple tools and oil, to keep it alive by maintaining it on a regular base.
After many years in service some sealing rings should be exchanged.
That's it.
Many farmers operate those machines till today at very low operational costs.
.
Since size limitation on the display in my living room the proportions need to be squezed, as they did on the TV edition.
Making it fully 1/25 scale would occupy much space.
Some changes will be made as needed.

Some parts do exist in two configurations.
Take a preview tool before printing.

The rotary cutter thing will be changed, made from steel spokes or shop sticks or similar.
A trailer for transporting the rotary cutter on the roads could be made.

The compartments behind the drivers seat used for storing the harvested fruits and the engine have covers.
Will design them at very last parts when everything fits.

The cabine could be omitted.
If I make it from acrylic plates it should have separated windows inserts or at least some cut outs and a sliding door.
The first model gave the driver the open sky.
Following models had a roof or cabine.
Later the cabine became standard instead of being an option.
