Every pie cut jig I make, in one purchase. 43 STL files. The 9°, 15° and 18° bulk packs together: 14 sizes at 9° (1.50" to 5.00"), 15 sizes at 15° (1.50" to 6.00") and 14 sizes at 18° (1.50" to 5.00").
Why the Complete pack. The three bulk packs bought separately are $457 ($149 + $159 + $149). PIE Complete is $365 — about 20% less — and covers every tube size and every cut angle you will ever need on a header, exhaust or intake build.

How many cuts do I need?
A 90° bend takes ten cuts at 9°, six at 15° and five at 18°. Fewer cuts is faster; more cuts is a smoother, rounder bend.
Print settings
My official settings for every G1Pro fixture: 2.5 mm walls, 2.5 mm top and bottom, 20% cubic infill, support-free, printed in Inland PETG-CF. Print one size first and check it on your tube before you commit a whole spool.
Licence — Shop Use
Buy it once and print as many copies as you like for use in your own shop, including on paying customer jobs. You may not share or resell the files, or print copies of the jig to sell. Need a print-and-sell licence? Get in touch.
