4" x 10" Shipping Tube on Clearance for $1 @ Michaels

[BigMacDaddy]

Might make some cheap big short fat rockets (although easier if you make your own nose cones, etc... since shipping tube will be thicker than traditional tube).

Small army of short-fat rockets unlocked...

Note: these weigh around 85g and have 1mm thick cardboard.

Word of warning -- these were not marked as clearance at my local Michaels so I needed to show the website to get the discount.



Reminder again of how I wish I had a website with ratios for body tube length to width to figure out what I could make with random body tubes. These will work for a 2.5x ratio.

Nice! Would you have a 4" nose cone on hand to test fit for us?

Sorry, I don't have any commercial cones that large.

I was just thinking about how since I 3D print all my nosecones I look at every tube as a potential custom build...

This is on my "To Build" list.

Nice -- that might be a 6" or 8" tube (unless he is a small guy).

I went by my local Michael's today and they didn't have the 10", but had 4"W X 12"L for $1...whoop! I bought the three that were left.

Oddly enough, there were 4"W X 6"L tubes on clearance too, but for $2.

I did a quick check of a Madcow 4" centering ring and the ID of these tubes are a tiny bit bigger and the tube is thinner, so maybe a good candidate to try fiberglassing the inside with a balloon.

If I get a chance to design any 3D printed parts for these I will share them...

That'd be great, thanks!

Its DIY - I printed it today on a new 3D printer I got yesterday...

Great find!

I posted a few designs for nosecones that fit in these mailers here (free):

That would be a serious upscale!!! Not sure I would want to get hit by that coming down...

Yes, certainly not your typical tumble featherweight recovery.

Make 2nd segment a AV Bay... The from there to motor, the segments separate, and "wiggle" on way down. At main deployment pop nosecone with parachute from 1st section.

Just a thought.
