These are angled corner sections of model concrete kerbstones for 7mm scale O gauge model railways, created to match up with my other design available which you can see in the first picture - KERBSTONES WITH ROAD SUPPORT https://www.cgtrader.com/3d-print-models/hobby-diy/other/kerbstones-with-road-support-7mm-scale-o-gauge-model-railway

Also available are dropped kerb sections for driveways and a section incorporating a rain water drain.

I have designed the kerbstones so that the elephant's foot effect does not protrude when they are printed flat on the build plate on my printer. I sliced the file in Lychee and printed it on an Anycubic Photon Mono X, using Siraya Tech fast white resin.
