Print Details:
Parts 1-5 can be printed in your favorite heat-resistant flavor of filament, I used PA6-CF with good results.
Part 6 is designed to be printed in a flexible filament like TPU.
Other parts required:
Tap threads in the Rear Top holes, and bolt the rear bottom to the rear using the 14mm cap Head bolts. Remove bolts from the rear trim and insert the spacer, use 40mm bolts to fix the rear bottom through the spacer onto the trim. Tap threads in the hole in Front Cap, use the 20mm bolts to secure the Front arm and use bolts to tension in place.
Cut roof rack extrusion to size, using Front cap as guide drill hole and fit M6 Rivet nut in place, bolt through with 20mm bolts. Fit and tension.
