About this 3D model
Say goodbye to warping and the noisy fans... This mod work well with the hotend stock fan mounted on the I3 (s also). (E3DV5)Only the extrusion cooling fan MUST be replaced by another model. (not necessary if you print only with ABS filament) Update 07 March 2020 :*******************************Added Sunon Maglev extrusion Fan references Update 15 January 2020 :******************************Following few requests, here are the link to the nuts and bolts used in this projectCase assembly : Self Taping screw http://s.click.aliexpress.com/e/_cmJxzL Fan BFB0512 assembly (extrusion cooling fan) or Sunon MaglevNutsM4 x 25 mm NYLON (because maybe you will have to reduce the thickness of the head inside the fanbox)http://s.click.aliexpress.com/e/_cmoLlrBoltsM4 Nylonhttp://s.click.aliexpress.com/e/_c3QzJJor Alloy Bluehttp://s.click.aliexpress.com/e/_c2E8TT Fan assembly (40x40mm Stock Fan or upgrade (see below))NutsM2.5 x 20mmhttp://s.click.aliexpress.com/e/_cm3UPp(kit M2.5)Bolts M2.5 inside the kit Update 03 December 2019 :******************************** Added an E3DV6 adapted Right side (File Right Side RB5 E3DV6) Added BL Touch Version for ED3V5 or ED3V6 Hotend (see below) Update 27 September 2019 : More than 10K Views and 1K downloads, It's a hit ! :)*********************************Thanks to all, please post your makes ! Update 07 April 2019 : Correct Mismatched link to 5015 Fan (thanks to Slobodan)**************************Update 29 January 2019 : Added Half air duct "half buse V1.3" see below****************************** After trying a lot of fanbox for hotend for the mega i3, I was often disappointed by the characteristics, including poor head cooling for the printing of PLA, hot air escaping through the underside which causes detachments of ABS (Warping). As you can see on the utimaker S5, the bottom of the hotend is completely closed to prevent cooling of the part by the bottom side.Lightening the fanbox allows the print head to be lighter and thus have less inertia, which allows higher print speeds, even without control of acceleration or jerk.The front deflector design force the airflow to go up, by this way prevent delamination effect. So I decided to create my own Fanbox for the I3 Mega.After a lot of working hours under Solidworks and a dozen impressions, the result is there .. All parts are print WITHOUT SUPPORT. Just choose the right direction for the piece to print.(see pictures) Print in ABS because it is resistant to heat.A finish with acetone is the most beautiful effect. (in a plastic box that seals tightly, place a sheet of aluminum foil in the bottom, wrap the inside of the box with paper towels, soak the acetone paper, place the ABS object on a stand (made for example wine bottle stoppers and toothpicks) so that the piece does not touch acetone, close the box for 10 to 30 minutes, and here ... The extrusion fan duct MUST be replaced by the following one: The Rolls Royce : Sunon MagLev (magnetic levitation bearings)https://s.click.aliexpress.com/e/_d6covxb(Don't care the yellow wire, tachymeter output, here it's not connected. connect only red and black wire) or an efficient but more noisy fan (classic brass bearings, (no ball bearings))FAN BFB0512HH 12V 0.32A Type 5015 http://s.click.aliexpress.com/e/cnapTa4o The extrusion fan duct is designed to provide an airflow efficient. the internal aerodynamic shape of the fan duct was calculated, simulated and measured using a thermal camera. The hotend original fan CAN be replaced by a very quiet fan Sunon MagLev (magnetic levitation bearings)http://s.click.aliexpress.com/e/bkBs4qMC or the Roll-Royce...Noctua NF--A4X10http://s.click.aliexpress.com/e/cBFASjxE ..only if you want to reduce the fan noise... This design works great with the stock fan. The bottom of the fanbox is closed to the maximum so that cold air does not cool the tray and the object when printing abs. Prior to the installation, you have to check your original anycubic hotend support is perfectly perpendicular, otherwise the new parts will not fit perfectly to the support. (see picture, mine isn't re-adjusted on this pic) Few M4x25, M2.5x20 Nuts & Bolts, few M1 self taping screws and you will be ready to print PLA, ABS without headache Led illumination will be added soon. 23 May 2018 : Parts "gauche.stl & "droite.stl" updated to V5, Top fixing holes has been adjusted, the two retention tips has been thinned because some guys report me the fixing screw of the little pcb with all connectors must be different in diameter on some batch of the printer. 10 January 2019 : Added "Half Buse V1.1 for the people who want to see the printing head in action or using a BLTouch like this onehttp://s.click.aliexpress.com/e/MizWXDX6 Beware the fact the cooling maybe less efficient with this optionparts are optimized to be printed verticaly (see pictures) ************************************E3DV6 HOTEND The E3DV6 Hotend is a great update you must consider..Here is the link to the part i use :http://s
