Threaded Rocket w/ Interchangable parts

thingiverse

Update, I corrected the cover to ensure it's now the correct diameter. This rocket comes together seamlessly as a single unit. At its core, the bottom three pieces are joined via screws, while the nose cone simply slides into place - allowing for the parachute to be ejected smoothly. The design draws inspiration from the established standards of the Estes company's rocket engines. I successfully printed all required parts without resorting to using supports or any internal structures, such as infill, other than a triple layer exterior shell (3). As I've only just begun experimenting with the actual flyability of this model - I highly advise you test its capabilities at your own risk before proceeding further. Instructions: Begin by printing the lower section of the rocket, and proceed to print the engine cover, if necessary, depending on your 3D printer's specific requirements and limitations in handling tolerances. It may be necessary to add this extra component to ensure that the engine remains securely locked into place. If you choose to exclude it altogether or replace it with a shortened variant, consider printing only one of either 'bottom middle' (BM) parts available for more flexibility. On the other hand, you should make sure to print at least 'top middle' or its equivalent short part (#2). The sole function of these is securing and keeping in place the entire top section - often also referred to as the nose cone.
