Train bogie model 18-100, H0 scale, HD (for resin)

Update 2025-12-19

A newer, more detailed Mk3 version was released here: 

Update 2023-10-13
Added 3rd variant with long coupler pocket. Length from bogie axis to end face is 24mm. Used it for the model of gondola car.

 This is a resin-printer oriented highly-detailed model of a train bogie series 18-100, widely used in USSR/Russian/CIS freight wagons.

The FDM-oriented version can be found here or here. Compared to FDM version, this one has much more fine details, reworked bearing holder, and different slider height (it is made prototypical).

The height from rail level to the top of bogie is 9.8mm when using 10.7mm wheelsets (36" prototypical), e.g. these from aliexpress. Sockets for wheelsets follow NEM 314 (Carriage Wheelset for Tip Bearings). **This model does not contain wheelsets!** I strongly advise using ready-made metal wheelsets for better rolling performance, but if you really want, you can 3D print the wheelsets too, the wheels can be found here, for example.

Center hole is for 2mm self-tapping screw or M2 metal screw, hole can be drilled out for larger screws.

There are 2 versions of the model - with NEM 362 pocket for couplings and without.

The minimum size of features is 0.3mm (in rare cases, 0.2mm)

The photos contain slightly older design, the current one differs in detalisation of brakes.
