Warning: Three-Dimensional Printed Parts May Break and Pose a Choking Hazard for Young Children. Many Adhesives Used Are Toxic, So You Take Full Responsibility for What You Print. PETG is Preferred Material. "Hot Melt" Glue Is Used Throughout the Entire Project. Duplo Can Be Annoying to Print as an Exact Friction Fit Is Required. Experiment with a Small Part like S1 or P3 and Check for Fit. If Parts Are Too Loose, Try Over Extruding a Little, If Holes Are Too Loose (They're Generally on the Bottom of the Part As Printed) So Squashing the Bottom Layers a Bit Can Help (IE Have a 0.1mm Gap But Have Slicer Set for 0.3). For More Unexpected Results, You Could Try Resizing the Part a Tiny Bit or Changing the Accuracy on Your Slicer. If Parts Are Too Tight, Try Mechanical Means to Remove Excess (Sanding, Drilling, Reaming, Cutting a Few Prongs Off) or Underextruding a Little. Printing/Construction Advice Turbo Fan Jet (J1, J2, J3) Print in Orientation Shown in File. I Used a Brim for Jet Parts As They Are Pretty Tall with a Small Base. Glue Parts Together in a Common Sense Way. Internal Jet (Intake / Exhaust Parts – IJ1, IJ2, IJ3) IJ2 Is Used for Both Intake and Exhaust. Print Intake IJ1 on an Angle So Its Front Rests on the Build Plate. Print IJ3 In Its End. Print 2 IJ2's and Glue IJ1 and 2 Into Them. Propeller (P1, P2, P3) Print in Orientation Shown, Other Than Propeller – Print This Flat Side Down. It Is Difficult to Print the Slot on the Propeller (P2) to Accept Nose Cone Well (P1). It Is Oversized but Still Needed a Knife / Engraving Tool to Clean It Up So the Parts Could Fit. If You Have a Working Cooling Fan, This Would Likely Help. Wing Tilter for Swept Wings (S1) Print As Shown, Just Make 4 as You Tend to Need to Clamp the Wing from Above and Below for It to Hold Properly. Tail (T1, T2) Print in Orientation Provided. I Found the Holes on the Base a Little Narrow. But These Could Be Loosed by Shoving a Few Duplo Prongs In at a Time and Doing This Lots of Times. Undercarriage Wheel (W1, W2, W3) Print in Orientation Provided, Mirror W2 in Slicer and Print One Normal and One Mirrored W2. To Hold the Wheel On Use Some M3 Bolts with Their Heads Cut Off. You May Need to Screw Them In on One Side W3 and Drill Out on the Other W2 to Spin Easily. Assemble in Common Sense.
