Various bits & bobs used including spice containers, a/c drain pipes, 3D printed resized pipes & fittings , balloon 6mm diameter tubes & card. The computer terminals are from Antenocities. 5mm ( hole size) chicken wire was used for the railings.
White PVA was mostly used with CA for the magnets.
The bases are made of double Pinsa box card ( just fyi Pinsa is a rectangular type of pizza native of Rome ). So if you can get hold of this type of box card it is some of the best around. Much sturdier than normal pizza card.... and it is obviously recyclable. I stuck mosquito netting to it to add texture.
Almost all the bits have 4mm magnets. Almost all because I made a mistake with the orientation of some of them 😒 ( now I've made a jig with 2 magnets & sprue to avoid just this ... about time !!! )
Anyway, to counter act this I used the heads of old 4 to 5'' nails ( cut down to size ) & 1 euro cents stuck to some of the pipes or terrain.
