I wanted a GREAT looking drift track for my home…but didn't want to pay the crazy prices.  

I decided I was going to create this curb model in different diameters so I could piece together a track however I wanted!  

Available in 3ft, 5ft, 8ft, and 10ft diameters.  Note - those are the inside diameters of the circle - each piece is 80mm wide, so add that to get a true OD.  

Good news - they are linkable/mixable.  So you can transition from 10ft to 8ft and so on to create a decreasing radius corner.  

The holes in the top pair with the drift walls - just use some 6mm dowel rods to get a tight fit!  

Printing:   I printed 2 per sheet.  Used PLA.  Reduced to 2 solid bottom and top layers, 5% infill.  Everything to reduce the print time.  

Another pro tip - I shrunk the parts 20% for a test - and they STILL WORKED!  Now I could get 3 parts on a print bed and they printed quicker.  Of course, this impacts your diameter as well, so plan accordingly.
