This is a multi piece 3d printable rocket for use with DIY rocket motors made with 5 inch long, 3/4 inch schedule 40 PVC. You can find multiple youtube videos on DIY sugar rocket motors. I based my dimensions off TKOR's video on how to make sugar rockets.

Assembly of this rocket is fairly straight forward. The longer piece with one end mostly closed off is the bottom. you can slide a rocket motor into the larger end and it will stop against the smaller end's "bulkhead". The small hole is to allow a parachute ejection charge to pass into the smaller section of tube that must be glued in place. (sorry i dont know how to to do alignment tabs in cad yet.) The nose cone should fit over the end of the tube just slightly and you should be able to use a screw to attach a parachute line. or if you dont use a chute you can glue this in place. the fins you will need 3 or 4 of depending on the look you are going for. (Again I dont know how to do slots in cad yet) attach the fins to the engine section with the fins longer end pointed down so they can be used as legs. you can try and put a slight angle on all of them with the same degree roughly. this should make the rocket spin slightly and hold a straighter course.

For launching you should be able to stick the points of the fins into the ground to hold it upright or if you have a launch platform. or piece of rod shoved in the ground. you can glue a straw to the rockets side and use that as a guide for launching.

I havent printed this yet so I cant say how well it preforms. I can say this is not a toy and when rocket motors are involved they are dangerous. You can find DIY rocket motors on youtube and TKOR also has a diy parachute from plastic table cloth.

This is a work in progress and I plan to make changes to how it goes together and how to build. I also want to put a loop in the under side of the nose cone so no screws are needed.

for printing. fins and lower rocket body I recommend 100% infill. position to print with the small opening facing down.

The upper rocket body I would recommend 4 walls or 100% infill. The nose cone should be light weight so it comes off easy when the parachute charge goes off. Id say 20% infill. and if you dont plan to use a parachute, use a soft tpu and make it as hollow as possible. this should provide a soft bumper when it lands to stop it from shattering on ground contact.

I would use abs, petg, or any tough material you have and can print.

I will update this when I am able;.
