    Nice reproduction!

    That 3.4" tube is sure a pain to reproduce these days. What are you using for fins?

    Did a full brain transplant on my Ender 3 Pro to get better quality parts. SKR v1.3 32 bit board with TMC-2208 Stepper drivers in Uart Mode. Now need to test out PETG and make some rocket stuff!

    But if you hold the cone the other way it turns the frown upside-down!:)

    What I think you ought to do is master the art of drooping nose cones like that, get a matched set, and use them for side pods.

    I use a home made cheapskate version of this crafted from a large cardboard box. Overspray settling hasn't been a problem. Overspray wafting out the front is the problem, giving interesting colored boogers the next day. (Yes, I know, I should wear at least a mask.)

    Take a box that's at least 2'×2'×3'. Tape it closed on both ends. Cut an opening in one side that leaves a border about 2" wide; the border keeps that side stiff even with the material removed. Once you're inside, you'll need to glue the inside end flaps to the outside end flaps that you've already taped; do this by lifting them, spreading glue underneath, then weighing them down. Once both ends are glued up, designate the end that's the top and punch one or more small holes. Through those holes you pass hooks with a right angle bend on one end and a 180° hook on the other to hang things from; said hooks can be made from cut up pieces of wire clothes hangers in various lengths as needed. It's a serviceable better-than-nothing booth. And yes, it would be a lot better with a vent fan; I just have to pick a fan that will survive paint exposure and figure out how to mount it and the filter in front of it. At which point I'll rebuild the whole thing out of hardboard or MDF or something. But this is, like I said, better than nothing for now.

    Turn it into a feature! That could look pretty awesome!

    It seems to me that the real advantage of 3d printing is not being confined to simple geometric shapes like cones, nearly any arbitrary shape is possible (I realize support and strength are still limitations).

    Found a
    North Coast Rocketry Launch Controller in my stash never used.
    Went to my local hobby shop and got a set of batteries for it. I like it a lot.
    tested it on some igniters and worked freaky fast.

    Also received in the mail a Estes 1:200 Saturn V
    Nice, but no fun. Already built, no assembly required.
    Will see how they both work after the summer heat is over here in texas

    It hasn't done that. It's bigger than it looks. I can actually get inside of it and stand about 3/4 of the way up. However, I am spray painting smaller rockets right now. Luckily, they have one twice as large if and when I need it. It's worked great so far. But we'll see.

    Finished my Mach 1 Black Hole. DD with Eggtimer Quark, Eggfinder Mini in the Wildman nosecone. I hope to fly it on the18th. at the PSC473 picnic and launch. I have various 29 reloads to try. I'll run some sims and see what I get. Would like to get around 1000' for a first flight. I'll be using a 60" streamer and 30" main. Weight without a motor is around 900g. Maybe the G52-8?

    I actually went to Walmart and found a flexible clear plastic box and cut it up for fin material, then hot glued it together to a ring of wood that will be held in place on the bottom by the Engine Nut.

    Today it was so hot out stayed in and worked on my Igniters. I soak off the cornstarch crap Estes puts on them and then use flammable glue and 4FFFF black powder. They ignite every time and even fire off 29mm F engines with these !

    The rocket is flyable. It now has the engine mount and chute installed. It does have decals, but I've heard mixed reviews of the decals from the kit. To prevent bleed through, others have apparently layered the decals with an undercoating of white before applying them. I may look into that, but I won't have time before this weekend.

    Today I found some 18mm and 24mm motor retainers in the recycling. The spout from the almond milk is a very good fit on a BT50 tube (an even better fit on BT50H foil-lined tube). The soy milk spout is just a little loose on a BT20 tube.

    Indeed. I am working on my first printed fin-can right now (an update of the TAO spin-stabilized-finless-sustainer-two-stage contest winner) -- I am lofting and sweeping all over the place.

    I am also going to print a repair/modification for the Mini-A Heli, the nose of which was blown off by the ejection charge when I launched it last weekend.

    20190806_183133.png

    That said, being able to print a simple cone to fit an odd-ball body tube let me finish this build in a much shorter time -- which was important in this instance.

    It was also pretty cool to be able to print up a replacement for the oddly-sized cone.

    That's funny. I had the same thought when I was throwing out my daughter's almond milk container a couple of days back!!!

    You guys inspired me. I hit Hobby Lobby to restock the 20 engines I blew through at the launch this weekend. I emptied the Bs, Cs and Ds. IMG_20190807_123328444_compress89.jpg Some new kits there too. It was nice to see a Cherokee-E.

    Working on a cluster rocket first one I’ve built been fun so far my fins don’t go though the body they have epoxy fillets though. Idk if it will make it but I’ll build another.
