Have us print this for you
PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
I created this to make Lego trains compatible with Kadee 743 couplers as I think these are much more convenient and cheaper then other systems with meachnics and/or electronics.
### Buffer versions and build
* I recommend printing these with 0.16mm layer height.
* The FULL version has shortened buffers to not interfer in turns. Print WITH supports with buffers facing down! Exclude the pin hole.
* The MINI version has no buffers and can be printed as oriented in the STL WITHOUT supports.
* The case of the 743 coupler needs to be modified to fit. Cut off the protruding parts on the sides with a knife.
* To mount the Kadee coupler you need a rod with 2mm diameter and between 12mm and 15mm long.
### Decoupler tracks
* For decoupling, you need magnets to fit under your rails. I used these 60x10x3mm with double sided tape attached.

* You have to file off some of the studs (6) to place the magnets.
* Use a 2x8 plate and 4 2x4 tiles to cover the magnets
