MGN12H G5+Mosquito/Mellow Tool Carriage with Part Cooling Ducts FINALLY TESTED AND WORKING - 24h Print Done, No Issues! Version with Precision Piezo Holder Available Too: https://www.thingiverse.com/thing:4189461 (btw, no clue why Thingiverse is not rendering STL's, they are all ok and available in thing files) I'm Testing with Some PRC Blowers "[Magic Dragon BFB0512HH 12V 0.32A 5015 Centrifugal Turbo Fan](https://www.aliexpress.com/item/32720441035.html)" that Are Not Too Powerful and In Rather Noisy Environment But Here Are Some Numbers (Average Values, Measured 3cm from the Device): * Ambient Noise: 48dBA * Blowers Powered with 9V in the Fan-Duct: 55dBA * Blowers Powered with 12V in the Fan-Duct: 60dBA * Blowers Removed from the Fan-Duct, Freely Floating 9V: 60dBA * Blowers Removed from the Fan-Duct, Freely Floating 12V: 63dBA I'm Not Sure How They Are Quieter with the Duct but… EXTRUDER: * **G5 - Tested** Works with Flex3Drive G5 * **BOWDEN - Tested** Originally I Made This for Myself to Use with Flex3Drive G5 (Awesome Remote Direct Drive) But It Can Also Be Used with Bowden Extruder. There's the Bowden Adapter for the Hotend, Looks Like a Standard Grove Mount Top That You Can Screw on the Top of the Mosquito/Mellow and It Has a Hole on the Other Side Where You Feed in the Bowden Tube. * **NEMA8** G5 Can Also Work with NEMA8 Motor as Direct Drive, So Without the Flex Shaft Thingy. I Have Never Tried It Nor I Have the STL for the Top Cap of G5 to Mount the NEMA8 on It So No Clue If It Would Fit Here or If Part Cooling Blowers Will Be in the Way. * **BMG** There Are Bunch of BMG Original's and Clones That Might Fit Here, But I Don't Own Any So Really Have Not Tried. IMPORTANT NOTES: * V3 Tested in Real Printing Conditions, the Brass Inserts Fail and Hotend Drops Out After Few Hours of Printing (Even Sooner); the Main Issue Is That "Cold" Side of the Mellow NF Crazy Hotend (PRC Clone of the Slice Engineering Mosquito) Gets Hot and That Heat Transfers into Brass Inserts and They Just Pop Out of the Plastic So the Whole Hotend Just Slides from the Filament Pressure. It Might Work with Original Mosquito If It Behaves as Advertised But I Doubt It. * V4 Tested in Real Printing Conditions Printing ABS, PETG, HIPS and PC (280C) and It Held Its Ground So It's Now My Main Extruder on Ender 5. * Make Sure You Have the Fan Cooling the Cold Side of the Extruder Blowing Non Stop, Maybe in Some Scenario It Can Work Without Fan But I Doubt It. * Aluminium Tape - In My 10+ Years Experience with 3D Printers and Part Design I Figured That Coating Printed Part with Aluminium Tape Will Reflect Heat and Even Thermally Incapable Plastic Like PLA Can Survive Around Hotend. I Have Pieces Printed in PETG That Are Coated with Aluminium Tape on the Side Where They Are Exposed to 300-350C and They Are Still Alive, Not Deformed.. The Tape Did Not Fall Off .. (The One I Use ATTM for E.g. Is Some "Scley 540", I Think It's Made in Poland) So I Advice Taping the Inside of the Carriage with Aluminium Tape. You Can Also Go Overboard with Aluminium Tape Like on One of the Images Attached. * Mellow NF Crazy Hotend Clone of the Mosquito, While Looks Very Similar Is a Total POS :( ... Don't Waste Your Time On It, It's Not Cheap and It Does Not Work, Especially If You Want to Print Low Temp Materials Like PLA .. Just Get the Original, It's Worth It.
