Build thread for this rocket is found at: https://www.rocketryforum.com/threads/13mm-snake-eye-bomb-rocket-build-thread.169009/ You'll need the following to build this rocket. BT-5 (13mm) body tube for center tube like https://www.apogeerockets.com/Building_Supplies/Body_Tubes/Low_Power_Tubes/13mm_x_18_Body_Tube_Estes_BT-5_size BT-50 (24mm) body tube for main tube like https://www.apogeerockets.com/Building_Supplies/Body_Tubes/Low_Power_Tubes/24mm_x_18_Body_Tube_Estes_BT-50_size 1/8" Launch Lug like https://www.apogeerockets.com/Building_Supplies/Launch_Lugs_Rail_Buttons/Launch_Lugs/1_8_Launch_Lug 1/2" rubber bands like https://www.amazon.com/gp/product/B003H54TY8/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 Thin cardboard, like from a cereal box. Mine was around .5mm thick and came from the divider cardboard in a canned cat food box. If you have cats and feed them canned food, this is where I got my cardboard: https://www.amazon.com/Purina-Fancy-Feast-Poultry-Collection/dp/B005OB3E30/ref=sr_1_21_0o_fs?dchild=1&keywords=Canned+Cat+Food&qid=1634932341&qsid=142-4151838-0244230&sr=8-21&sres=B08MLBGGB5%2CB00283MYSI%2CB07QC8CBRY%2CB084S93JHP%2CB08MKQS588%2CB00JVHSGUO%2CB006TAD0AW%2CB08MKWMGXT%2CB0061LRULE%2CB00CK96HUG%2CB06X9GL9MG%2CB006FTJ0NI%2CB07NRC3B7K%2CB005OB3E30%2CB00JVHSGVS%2CB078JYLL18%2CB07CX9STN3%2CB001G0NKV4%2CB06XZYHSS9%2CB002CJG1YQ&srpt=PET_FOOD You should be able to make 4 or 5 of these rockets if you ordered those parts from the links above. Print 4 Bottom arms with support (only part that needs support) Print 4 top arms Print 1 of everything else The fin template and cutting guide are helpers for construction and are NOT used on the finished rocket. Note that the Bottom and Top arm holders appear identical. The Top arm holder has a slightly larger inner diameter, however as it needs to slide freely over the 13mm tube. There is a small circular dimple on one of the upper surfaces that can be used to tell it apart. I marked that dimple with a paint pen to make it easier to see.

I gave up on the "helicopter" version. It spins alright, but it basically tumbles as it spins and that ruins the effect for me. I much prefer the regular version. https://www.youtube.com/watch?v=07eqrBgJ3gg
