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

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

The North Staffs battery powered shunting loco is now preserved in the NRM in York. I felt that it would be appropriate to make a battery powered model of a battery powered prototype. The greater part of the loco is 3D printed, with a couple of N20 motors and wheel sets from Peter Korzelius (or you can print your own wagon size wheels).

This became the standard LNWR van from the mid Edwardian period up until grouping. They were used for traffic until the mid 50s at least, and some survived in departmental use for much longer. Note that it has been designed for resin printing on an Elegoo Saturn or similar. I don't know whether it can be printed on a filament printer (but let me know if you try!)

This is the short wheelbase version. The brake gear for this wagon is unusual as there is a small operating lever pivoted on a small bracket attached to the buffer beam and a connecting link to the centre brake gear pivot

This is an update of a previous model with a one piece top plate
