Many G1 modellers who have their own rolling stock use the 'Really Useful' brand of plastic boxes, particularly the 22l version for transporting and storing G1 coaches.
A problem with these boxes is that if stacked and then slid over one another the standard blue polypropylene lid clips can come dislodged. If one is not careful one can find that trying to lift 2 boxes just results in lifting one and a lid.
The object of this clip design is to provide a more secure clip that does not project above the box top and prevents dislodging.

Tref’s G1MRA Anniversary Brake Van Project was  a van to celebrate the 75th Anniversary of G1MRA, with a contribution from the 3d Printing Circle.

It is intended to be easily printed and assembled on the majority of FDM printers.

The initial publication of this coach is an attempt to make a simple model for the "Christmas tree" project.

Some discussion is needed to simplify the design to make it easy to print. Currently the break gear on the ends of the coach are rather fragile and the body, if printed on a resin printer probably needs dividing into two for most printers.

The smaller components were designed for resin printing. The body, when resin printer is in two parts.

Model of the SER Clapboard Waiting Shelter based on the drawing by Brian Hart in the Elham Valley Railway book. 

10mm scale. Slots provide for 1mm clear plastic sheet to be used for window glazing. 

Wooden underframe five plank wagon produced in huge numbers during the 1920s. Lasted into the 1950s.  This model was originally on the Groups.IO site but got lost in the move. I have taken the opportunity to improve some details. It now incorporates a barrow ramp at the top of the door, and the brake gear rack has been considerably narrowed to come closer to the prototype.  The W irons are now less of a tight fit.

Freelance model of a Storkleg locomotive steam toy of about 1900.

Tool developed for bending handrails for the BR 20t Brake Van Project - but obviously its use extends beyond that...

Designed for and tested on 0.8mm diameter stainless steel mig welding wire, that is otherwise rather difficult to get a neat, tight, bend in.

It utilises a modified M5 Hex head bolt, with a plain shank element of at least 20mm, cut and slotted at 1 end 5mm deep - see the .STL, just don't expect a 3d printed version to work! It uses a second bolt (or second part of the first one).

Sectional track each printed as one piece.

After the second world war 10 War Department Class 08's were purchased by the Nederlandse Spoorwegen in 1946. Because they were not equiped with Westinghouse brakes, they could only be used for shunting services (500 series). The series 600 and 700 were fitted with the required brakes to operate on the main lines. The exterior of all the series is almost identical.  

Stanier's first long wheelbase guards van, built from 1933.  Very much an alpha release as I have not managed to put together a completely satisfactory model myself. Please feed back any issues found.

Chassis and gearbox for 1910 Greenly designed Great Northern Gauge 2 0-4-0 Saddle Tank. This model was originally electric when made in 1910 but came to me without chassis or mechanism. The outline follows Greenly's design and the mechanism is a modern 385 motor driving through my standard bevel wheel gearbox. Power is supplied by 2x 26650 Lipos and running time is several hours (at least).

This is some openSCAD code and stls for an L shaped corner clamp. Given the need I will try to enhance this code further at some time.

Hopefully this will prove usefull to someone. Does not need supports to print.

The first parameter "type" is there for future additions of different clamps.

It is sometimes desired to combine the use of a slicer program with a 3d Printer that was not originally designed for it. This can occur when changing slicers or using older generation printers. I had a particular need to use an ageing but large and still excellent Taz 5 3d printer, with Prusa Slicer, which is one of the leading slicer programs currently (2023), under continuous development. Prusa Slicer does support many third party printers but not the Taz 5. After searching I came across a Reddit/Lulzbot link to a Github project that is aiming to link Prusa and Lulzbot in this way.

Pug Saddle Tank -Revision 2 – Optional changes Aug 2023
This update provides:
1.     Revised frames and frame stretchers to allow access for a ball driver/screw driver to the frame side screws with clearance from the wheels. This aids assembly.
2.     A revised footplate moves the battery holder forward to give clearance for a firebox LED if desired. Also this footplate accommodates a Hornby HM7000-21TXS Bluetooth DCC decoder and connection adaptor board in place of the previously fitted 'Locoremote' controller.

A simple gauge to check for 45mm track gauge & buffer heights. Track gauge faults cause derailments. Buffer height variations lead to buffer locking on curves & then mysterious derailments on straights.

Four wheel horsebox with groomsman compartment built by the SER on an 8'6" wheelbase chassis. Would have likely later been modified by the SECR to have brakes or at least through-piped. These units were used into SR service and were more numerous than the 6-wheel design. Drawn in 10mm scale

The SR precast concrete PW platelayers hut, 1:32 scale, four files zipped into one folder.

Drawing & STL files from Ole Holm's article in G1MRA NLJ 276 on making a diamond crossing. G1MRA members can read the article online or in their paper copy on pages 41/42. Non members will need to find a G1MRA friend to realise what they are missing.

G3 Track, 64mm (2.52") Gauge Curve 700mm radius, straight 300mm, turnout, end stop and 90-degree crossing. Should be printable on 220 x220. Peter Davis

Folder for some experimental BR Mark 1 coach STLs. The models are all aimed at using the Creality CR-30 belt printer which allows the whole coach to be printed in one length.

A selection of models loosely based on the popular series.

A short length of curved track (functional rather than aesthetically pleasing) with a sliding section to allow a dip or rise to be incorporated to challenge your springing or compensation
