BEFORE DOWNLOADING THESE FILES, PLEASE CONSIDER HEADING OVER TO MAKERWORLD AND DOWNLOADING THE FILES INSTEAD. THIS SUPPORTS MY EFFORTS TO A HIGHER DEGREE AND ALLOWS ME TO CREATE MORE HIGH QUALITY MODELS. OTHERWISE, ENJOY THE MODEL!SUMMARY:This model is a replica AH-1S Super Cobra attack helicopter used by the Army and Marines. The model is designed to print and assemble easily, so there are minor modifications to the overall design in order to do that. If you come across any issues, please leave me some feedback. Assembly instructions are found below.PRINT SETTINGS:Global Settings:0.16mm Layer HeightArachne Wall Generator3 Wall LoopsGyroid InfillOuter Wall Speed: 100 mm/sOverhang Speed:25,50%: 40 mm/s50,75%: 20 mm/s75,100%: 20 mm/sCabin:No object specific settings changed, uses global slicer settings only.Tail:Enable Support: Paint them on under the stabilizers only.Normal (Manual)SnugOn Build Plate OnlyOnce printed, I use a deburring tool to clean up any rough surfaces on the overhang of the tail as well as the bottom of the stabilizers.Wings/Cowl:Brim Type: No-BrimEnable Support: Painted on under the wings only. The remaining overhangs will print as is.Normal (Manual)SnugOnce printed, I used a deburring tool to clean up the bottom of the wings.Rotors, Landing Gear, Mounted Turret:Layer Height: 0.12mm8 Wall LoopsPrimary Rotor Brim: Outer Brim Only and 8mm Width.Turret:Enable Supports: Normal (Auto)SnugOn Build Plate OnlyOnce printed, I used a deburring tool to clean up the bottom of the turret barrel. You’ll also need to remove the brim from the rotor and landing gear.Windows:The windows were designed to print on the topside so you can use a patterned plate to create visual effects.There are 3 windows which need supports enabled. These are the rear left and right windows as well as the rear top window. The two side pieces may print fine as is, but have a very small angle at the corner. I’ve printed them successfully without supports, but why not? The top rear will definitely need the supports as it wraps slightly around the top.Enable Supports: Normal (Auto)SnugOn Build Plate OnlyASSEMBLY:The assembly requires no glue, but I recommend using super glue if this is going to be played with. The fit is fairly snug for most components, so all you need to do is press them into place. The connecting joints have sloped holes, so as you press the pieces into place, they will tighten down. I used a small clamp to make sure they were all pressed in sufficiently.Assemble the tail and cabin by inserting the alignment pin and pressing the pieces firmly together.Insert the wings into the cabin and press firmly into place.Insert the smaller alignment pins into the cabin and press the cowl onto the pins.Press the windows firmly into place.Push the primary rotor into the slot. This will require a little force, so I recommend either using a clamp and slowly tightening until it pops into place, or hold the piece parallel to the slot as much as possible and press directly onto the center of the rotor so you don’t bend the connector. Once it snaps into place, it should spin freely with no slop.Push the tail rotor into place. Try to press slowly and straight so you don’t snap the connector.Push the nose mounted turret into its’ socket. This will be tighter than the other two and once it snaps into place, it will have mild resistance when rotating.Finally, press the landing gear into the slots on the cabin and you’re done.
