Prusa MK3s upgrade fan duct

thingiverse

Update: June 6, 2019. I've crafted a brand-new version with even more open space and robust walls. It's clearly visible in orange in the screen shots (V1 in cyan, original in red). Keep in mind that this version is designed specifically for use with socks, and because the "front" wall has been moved back 1 millimeter, it may blow onto the heatblock slightly more. A few adjustments have been made to the Mk3s fan duct. The main differences are: • The wall thickness and internal columns have been beefed up for easier printing and increased strength. • The gap between the fan and the heatblock has been enlarged to provide room for a silicone sock In the renders, red represents stock, while cyan showcases the new design. Performance is remarkably similar to the original.
