Modelling Roof Trusses for Scratch Building

Modelling Roof Trusses for Scratch Building 3D print model


As part of my group of designs designed to help scratch builders I thought it was only right to include roof trusses.

These large A frames are ideal for anyone trying to create a scene with houses under construction.

I have created two sizes that have been slightly over engineered to allow you to scale them up or down to fit the specific size you require. The botton rafters are either 8m or 6m long which is 105mm or 79mm long in the scale I have used 1/76, hopefully you can scale these to the scale your modelling in.

The angle of the roof is 35 degrees.

As per normal with my designs there is a balance between accuracy and printability, hopefully not affecting the look of the model too much.
