That school 3D printer sure puts out a nice smooth finish on the parts!!

Bambu labs P1P 3d printer. I am going to get one to replace my old 3d printer at some point. Best parts about it are that it levels itself, it takes timelapse videos, and makes amazing quality parts. I never could get my 3d printer at my house to stop making spider-webby parts, no matter what I did. I did a test on the 3d printing splicer and the Dragon Capsule takes 27 hours on my printer and 7 hours on the school printer. The school printer parts are still 3x better quality.

I go to private school.

I don’t go to a private school but my middle school did have a set of 3d printers, they never told us who to go to too use them so they eventually gave up and gave them to some other school.

Max-Q has a much smaller falcon 9 model and I've been wondering the same thing. I want to try it, but I suspect things won't go well based on the results that @BigMacDaddy had with his TWA Moonliner.

My guess is the MaxQ version would fly well that way, but on landing parts would go everywhere!

I work with a middle school teacher on rocketry. She says they have the printers, but no idea how to use them or what they should make.
However, they did manage to finance (through private donations) an e-sports facility and have started a team.
Priorities??

Ok guys I think that's enough arguing about waffles

I'm not arguing about waffles, but wondering... Can you attach grid fins with maple syrup?

I think the IT guy knew how but he hates kids so I didn’t want to go there. (It’s not his fault, he has to fix all the problems they make)

Toothpicks. Learned that watching "Fifty First Dates".​

This rocket is much longer than the Moonliner so it may be more feasible to use drag from those open struts to make it stable.

However, I also warmed up to clear add-on fins after seeing how invisible they were in the Moonliner.

Maybe you can find a way to hide the clear fins inside, below, or between the struts...

 

[ljwilley]

Already said I'm not going to open the struts. Just using clear fins.

Liking the build so far
Think your idea of having essentially 2 different booster tubes is a good solution to the looks vs flight debate
Keep up with the posts!

 

[ljwilley]

Today I 3d printed the nozzles that have a central hole for flight:


And.... uh..... here's another picture of the der falcon max:
(i'm sorry I couldn't resist)




I also have another timelapse video!

I'm sorry.... but I'm starting to like this rocket as-is!

 

[Simon Auty]

I’m with you TechRat -can we have a Der Falcon Max kit?…

 

[ljwilley]

No, but when I finish 3d printing all the parts I will try to attach them all with masking tape for a good picture!

 

[ljwilley]

So, I have finished 3d printing all of the parts. I also laser cut the centering rings and was able to acquire some tubes for the build. I still need to buy the lower tubes, but this is a start! I plan on making the motor mount 29mm because it fits well with the nozzle assembly. Should fly well on baby H and I motors!

 

[ljwilley]

Motor mount has been assembled, just 2 plywood rings, a tube, a motor retainer, and tons of epoxy.

 

[KenECoyote]

I think the fins look grate.

 

[ljwilley]

HOW ARE YOU COMING UP WITH THESE!

 

[ljwilley]

Today I decided to paint the Dragon Capsule.

I painted it white and then masked it:





Then painted it black!

Food For Thought... maybe a build for another day?

What a coincidence! Flew mine yesterday! I tried to fly it a week ago but it went unstable. Then tried to fly it yesterday, but the delay turned out to be too long and it was destroyed. The D12 is just not powerful enough. I am planning on buying a bamboo lab P1P printer, and once I get it I will make another and fly it on a quest D22. The videos and pictures of the aftermath are on my dad's phone, I will post them when I can.
