◆ Clay
Corrugated roofing sheets with overlapping seams, nail heads and a few dents. Shacks, sheds, barns and post-apocalyptic scrap terrain.
Wavy corrugated sheets with a 4 mm pitch, overlapped at two seams per repeat with a row of nail heads along each, and a few shallow dents where something hit them, the tin roof of a shed, a shanty or a wasteland bunker. Roll it into air-dry clay, foam or polymer clay for shed and barn roofs, shanty walls, fences and scrap barricades on post-apocalyptic, western and modern wargaming tables, or for model railway goods sheds.
Made with our free texture roller tool, not modelled by hand: we drew the pattern in code as a seamless picture, uploaded it, and set a roller 30 mm across and 80 mm long with an 8 mm bore, the pattern raised 1.5 mm and repeated twice round and twice along. The zip holds the roller and the tool's own fork handle with its two retaining pins, as two STL files, plus the pattern picture, so you can remake the roller at another size or depth.
Every roller in this set is the same size and fits the same 131 mm handle, so you print the handle once and after that only rollers: pull the two pins, swap the roller, push the pins back in.
Shown as a 3D render of the printed roller in its handle on the clay it has pressed, not a photo.

Print the roller standing on its end and the handle and pins lying flat, all as exported, no supports.
Set the roller between the arms of the fork and push one pin through each arm into its bore, hex head outwards; the roller turns on the pins.
Roll the clay to an even thickness first: 4 to 6 mm for terrain and slabs, 2 to 3 mm for jewellery and ornaments.
Roll across once, in one direction, with steady, even pressure, and lift off at the end. Going back and forth doubles the pattern.
Pull the pins to swap to another roller from the set, and wash the roller in warm soapy water after use.

The ridges are 4 mm apart, which reads as heavy corrugated iron next to 28 and 32 mm miniatures and as ordinary roofing at 1:35 and on larger model railways. For finer corrugation, upload the pattern picture from the zip to the texture roller tool and raise the repeats along.
Roll polymer or air-dry clay thin, about 2 mm, texture it and cut ragged sheets. Once dry or baked, prime black, paint a dark metal, then sponge on browns and orange in patches and drybrush the ridges silver so the rust sits in the troughs.
Yes. Every roller in this set is 80 mm long and 30 mm across at the base, with an 8 mm bore, and every zip carries the same fork handle and pins, so you print the handle once and swap rollers by pulling the two pins.
About 2 h 50 min for everything on a current printer at 0.2 mm layers: about 1 h 15 min for the roller and 1 h 30 min for the handle and pins. Once you have the handle, each new roller is only the first part. The times are estimated from the parts' volume, not sliced.
