FAMMRR121 Kiruna Wagon Helix Dumper H0 scale 3D print model

UPDATE 2024-10-26!

I fixed an issue with the center parts of the Hinge at the pan. For the fix there is a V3 for the pan!

UPDATE 2024-10-24!

some changes in the Addons (orange Color in the pictures):

1. Handwheel on the hinge side is V2 with a small change to not clash anymore with the hinge even though it is not scale
2. Handrail to climb up the wagon added in 2 versions (didn't print them so far), first in 0,5mm which is more scale and then with 1mm for easier prints.But i still recommend to drill a small hole and use a 0.5mm wire to create them.

UPDATE 2024-10-23!

Accesoires added (marked yellow in the overview pictures), i recommend to search for pictures, i don't took any good myself so i couldn't upload them here:

1. Handwheels, one on each Side, see pictures
2. Bogie Step, one on the bogie far side of the hinge
3. Pipeholders (for 0.5 and 0.3 wire) 6 on the far side of the hinge on the frame
4. Brakecylinder, 2 versions, refer to pictures for position, Brakeline is the 0,3mm from the Pipeholders.

For the handles to climb up the wagon i recommend aswell to bend it from 0.5mm wire with reference pictures, but maybe i will add a 3D print version later that will have thicker diameter.

UPDATE 2024-04-12!

1. V2 i found a rubbing point on the pan from the wheels at a turn radius of 360mm (Märklin K, normal cirle 1 )
2. The pan is updated with a lower bottom curve to prevent that and might be possible for industry radius (not tested yet)

Initial Upload 2024-03-22

1. V1 is the baseline I uploaded on march 22nd. Parts in a rustbrown of the overview pictures

For my Modelrailroad I started to design the FAMMRR121 from KirunaWagon, as well known as Helix Dumper, they are designed for continous unloading by driving through a helix (will be uploaded as seperate Model).

so far I only have the the Bogies, the Frame, the Pan and the NEM 362 slot.Minimum Radius tested is 450mm so far.

I will update the model constantly until I'm finished and add more details like the brake cylinders and some tubing.Since i have another job i could not promise when it will be donemaybe you need to drill the wheel bearing in the bogies a bit and add some oil

Pins for the couplers are flush at the top and secured with a drop of supergluefrom the bottomside add a drop of oil

ballbearing pin needs to be secured with a drop of glue.

Install the bogies with a drop of oil

Important!several changes were made to adjust the Model for Modeltrains

• NEM slot is lower than the original
• model is a bit wider for stability and added the parts for the helix (it will need a guide to prevent the wagon from tiping while unloading)

you will need

• 4 axles letght 24.4mm / diameter 10.4mm (for example Märklin 700580)
• 2 NEM 362 couplings (for example 7203)
• 4 small springs to keep the coulping aligned (just startet testing with Märklin 7194)
• Small Ballbearing (AD 7mm / ID 3mm / width 3mm)
• 4 small pieces of 1.2mm wire for the hinge of the pan + 4 larger for the springs

For printing:

• 4x Axle_KirunaWagon_HD.stl is only if you want a standing Model, i did not test it !
• 2x NEM362_KirunaWagon_HD.stl
• 2x Pin_NEM_KirunaWagon_HD.stl
• 1x Pan_KirunaWagon_HD.stl
• 1x Ballbearing_pin_KirunaWagon_HD.stl
• 1x Frame_KirunaWagon_HD.stl
• 2x Bogie_Kirunawagon_HD.stl

Later I will make a build video or a pdf with instructions.

Fell free to write me if you found errors or have questions i will answer them as soon as possible.

Check my UnloadHelix aswell https://www.cgtrader.com/3d-print-models/games-toys/toys/unload-helix-for-fammrr121-in-h0-scale-kiruna-wagon-helix-dumper

I printed the parts with a 0.05mm Layerheighta mix of 80% ABS like and 20% Monocure Flex 100 to make the Printed Parts stronger
