These spacers are designed for use with my TrackToolz sets. They will work with any scale, but the 33mm spacing is the standard spacing of Kato N Scale Unitrak and is used on T-Trak modules.
The set includes all four spacers shown: 2 two track spacers, 1 three track spacer, and 1 four track spacer. The keys on the spacers fit into the notches on the tools, and with a rubber band wrapped around the hooks on the tool and over the top of the spacer will stay in place during use.
If you need longer spacers (5, 6, or more tracks, up to the 60cm limit of the 3D printer) let me know and I can make them available.
