The project uses parts from the original AMS from BambuLab.

Shopping list:

• bearing 618/4 4x9x4 - 8 pieces,
• bearing MR137 7x13x4 - 8 pieces,
• threaded insert M4x8.1 - 30 pieces (https://cnckitchen.store/products/gewindeeinsatz-threaded-insert-m4-standard-50-stk-pcs),
• threaded insert M5x9.5 - 6 pieces (https://cnckitchen.store/products/gewindeeinsatz-threaded-insert-m5-standard-50stk-pcs),
• smooth rods linear shaft 4mm
  ... also, some rubber roller, something to replace the front roller from the original AMS. Personally, I used something like a rubber fuel hose with a diameter of 11 mm and an outer hole diameter of 4 mm. It's important that your roller doesn't have an outer diameter greater than 11mm.
