T-TRAK-Z module collection

thingiverse

Here's my T-TRAK-Z module collection. I cut mine in MDF, but 1/4 birch ply might be a better choice if your CNC or laser can cut it cleanly. The single double has an integrated backboard - if that isn't your thing just cut another front for the back. The corners are curved to match the track setback and are dimensioned for 2.75 inch hardboard fascias all around. The modules in general require DIY foot blocks which also perform as inside corner braces - I rip 2x4s into sections that I can drill and insert t-nuts and bolts into for feet.
