This is a fully 3D printed model rocket designed to be used with 13mm Estes model rocket engines. It weighs a little more than 30g without an engine. I printed it in PLA+ with a 0.4mm nozzle at 100mm/m with a 0.2 layer height, also make sure to use supports. To assemble, glue the engine mount into the bottom of the main body making sure to put it in the right direction (see photos for alignment), tie a shock cord into the nose cone and use a shock cord mount (or a piece of paper) to attach the other side to the inside of the body tube, lastly attach a parachute to the shock cord close to the nose cone (I used an Estes 8in chute).
