With this mod, it is now possible to buy a whole Nextruder in pieces without the need for buying a MK3.9 Kit.
This mod removes the need for the missing 'Pin 2.9x8.5', 'Tubular spacer 13.2x3.8x0.35', and the 'Spacer 6x3.1x8'. These are still not available to purchase on Prusa eShop - See assembly link at the very bottom for images.
