About this model

IMPORTANT: Get the latest updates for this model here on PrusaPrinters. In 2021, all updates and uploads of new models were moved to PrusaPrinters, of course still free and under the same conditions... :) In the Anet A6 kit the 40mm fan is bolted against the cooling rib to keep the filament assembly drive together. This is done without no support for the fan. I made this spacer/standoff design to give proper support for the 40mm cooling fan and make the assembly more rigid. To make assembly easier the two spacers is interconnected with a bridge with correct spacing, just insert it into the cooling rib as shown on the photos.
