I designed this for my RC garage. Please note: This is not to scale. It has 3mm holes to attach together. On mine i put 3mm screws and nuts on. Please note: This is not 100% perfect as i have not had to much experience designing. This may require sanding and need holes drilling out. This moves up and down once built. Enjoy :) I printed mine in white them painted using Tamiya spray paints.
