Printrbot Simple Metal Fan Shroud
Description
50An6Xy06R6N'S Version 7.1 Didn'T Fit All Too Well On My Simple Metal. It Scraped The First Print Layers Off The Bed And Was About 1.4Mm Too Long Towards The Z-Probe. As A Result, The Ubis Hot End Was Offset From The Centre (Towards The Fans Side.) It Also Hit The Printer Frame Above The X-Motor When Homing Y And Z. I Have Modified His Design Slightly So That My Hot End Is Centred Within The Shroud. I Decreased The Profile By Approximately 1Mm In Order To Better Clear The Bed And Not Scrape It. I Increased The Clearance Where It Is Near The Printer Body On Homing. V7.1.2 Is Similar (Part Printed In Blue), But I Increased The Internal Volume By Adding Height To The Portion That Surrounds The Extruder (To Try And Reduce Back Pressure.) Print Results: So Far So Good, A 3Hr Print Came Out Extremely Clean. And No Clearance Issues At All. Note: I'M Not 100% Sure If The Sw 7.1 File Corresponds To The 7.1 .Stl File In Terms Of Exact Dimensions As Something Was Most Likely Altered Inadvertently.
