These are based on a old kit that is no longer in production. I managed to make the details smaller than the original kit, thus this 3D printed kit looks better. You with need to trim and sand edges and pieces. The Center and Side builds a 20cm walkway. You can extend this with the Extension STL or shorten it by trimming pieces to fit your needs

Tools Needed:

Hobby Knife for cleanup, trimming and cutting parts to desired length.
Sand Sticks and Files for cleanup.
CA Glue

Note: Handrails are 80 and 120mm in length to create over lap and help with assembly of the 100mm platforms.
