anet a6 open-fronted fan duct - with support clip!

thingiverse

I tried a bunch of other fan ducts for the A6 - the round ones don't get great airflow because they're all pushing towards the middle - and the only semi-circular ones I could find still obstructed the view of the print head. So I built this one for myself, but you might find it useful - feel free to drop in any suggestions on how it works for you. I found that over time, this duct starts to sag - the vent on the fan isn't rigid enough to keep it in place - and eventually starts snagging on the print. So... I've posted an updated version that extends up the right-hand side and clips onto the print head, so it's a much more secure solution. It was originally designed to hold an auto-level sensor, but you don't need to use it. It's the "Duct and AutoLevel Clip - v4" thing, and I've included the g-code with supports that I printed it with. Also added a version with the clip, but without the auto-level sensor mount - it's just straight up and down, so should be easier to print. You need to print this quite densely to ensure it is air-tight - use 3 shells and 100% infill - maybe even 125% flow to make sure the air is all getting to where it needs to go. Update - I've added in two new versions, a full-circle clip on, and an open-fronted clip on, both with new improved jet nozzles. These are still experimental, but feel free to print them and let me know if they need any improvements. Note: All these ducts require the adjustable extension piece to be printed and inserted in the top to allow them to fit into the A6 fan housing. Print Settings Printer: Anet A6 Rafts: No Supports: No Resolution: 0.2 might work, but 0.1 is better for a good fit Infill: 100% Notes: You need to print this really densely - use 100% infill and 125% flow to make sure it doesn't leak through the print. It's in two parts - the duct and the extension. I needed to add a 5mm brim to the extension to get it to grab the platform. The advantage of this duct is great directional airflow, less chance of snagging, and you can see the print as it happens. Hope it works for you.
