I am now happy with my 3D printed 9mm gauge wagon turntables, so they are now available.
The 24mm diameter version is small, the 48mm might be more suited to narrow gauge, and a friend suggested I do one in-between, which I initially declined but because I can use its size for other scales/gauges I will do a 36mm diameter version. This will be just big enough for anyone using the Peco 15ft wheelbase chassis.
Best link to webshop is via my website below. I am trying to group items related to scale and gauge, so turntables for 9mm gauge are under several headings . it is not possible to amend headings /groups so easier to introduce new ones.
