This is a version of David's gearbox in which the casing is screwed together from individual parts, making it easier to print and assemble.
Only the gearbox casing is my design and is based on David Viewing's original and Donald Picket's adaption of this for home printing. The gear wheels are taken from Donald's files although I have made one or two adaptations to help fit the casing.
This is a 3D printed travel case for the G1MRA Greenly starter locomotive.
A more or less there version of the short lived Class 17 Clayton. As the loco is more or less a mirror image, print 2 of most of the parts.
Bogies are designed around the Fosworks units with top hat bearings.
Handrails etc. 1mm brass wire.
There is adequate room inside for directional lights (3mm bicolour), headcode lights (use Fox transfers), and sound.
I would construct the two bonnet sections using self tapping screws, before joining the two halves together.
LNER designed BK container to Diagram 31. 200 containers were built to this design.
In LNER days, these containers were painted Oxford Blue with yellow lettering in a "Zig-Zag" colour scheme promoting furniture removal.
These would be seen on conflats, Lowfits*, 3 plank wagons and high sided open wagons. High sided wagons were sometimes used to prevent the doors being opened in transit and pilfering of the load.
*BR prohibited use of Lowfits for containers but photos show them being used in LNER days
LNER designed BD container to Diagram 29. 300 containers were built to this design.
In LNER days, these containers were painted red oxide with yellow lettering.
These would be seen on conflats, Lowfits*, 3 plank wagons and high sided open wagons. High sided wagons were sometimes used to prevent the doors being opened in transit and pilfering of the load.
*BR prohibited use of Lowfits for containers but photos show them being used in LNER days
This model is designed from drawings published in "Historic Carriage Drawings, Vol 3, Non passenger coaching stock" by Peter Tatlow
It's the 'Blue Book' (ISBN 1-8998 16-09-7). Also consulted were, photographs available on-line from many sources supplemented by viewing vans where I could.
These coal loads have been generated using the coal load generator in OpenSCAD loaded by Les Coombes, many thanks to him for making it available. I have used this to create some loads of the right size for the 1923 RCH mineral wagon, and also created a base to set the coal load at a suitable height. As the coal load generator is quite slow to run (on my laptop anyway) these models may help save time for others.
I've done some work using openSCAD to replicate the gearbox used on the Greenly starter loco.
The initial brief I gave myself is to create a clone of the gearbox, not necessarily identical but close enough that it can be used as a replacement in the loco.
The aim was to allow myself to experiment with different gear profiles and ratios, primarily the use of herringbone gears rather than the straight spur gears used in the original.
I've created a 3D printable G1 track for indoor shelf type layout. With 1800mm radius curves to be suitable for 4-wheel wagons and small locomotives.
27 June 2026, I replaced the Throw Bar 71, with Throw Bar 71.1.
1 July 2026, I replaced the Throw Bar 71.1, with Throw Bar 71.2.
This section contains some add-ons I've designed for the G1 MRA Greenly starter loco.
Currently this consists of:
