Printed a Dragon Crew nosecone for BT-60. But now I want to scale up to 3", I think. Printed an escape tower for the Estes Mercury rocket as well -- all as a single print to avoid gluing those three sections together...

STL files for the 54mm apogee nose
to finish,
- drill / tap for 1/4-20 eye bolt
- drill tap for 10-24 top mount
- drill tap (4 places) 4-40 altimeter mount
- drill tap (1 place) 4-40 for wire holder
- drill tap (2 places) 4-40 for battery retainer
- drill / tap (3) #6-32 holes in the base (nosecone attachment)

A 4", PETG version of the Estes BNC-50X for my upscale Astron Sprint. Printed in two parts for height, and CA'ed together with a tapered coupler ring I printed for the purpose.
Might strengthen the joint with JB Weld, but the CA gel alone seems to have made a damn strong bond in the PETG.
The shoulder is short (again, for height), but sized to go into a coupler tube, which will be the actual shoulder going into the body tube.

Printed IPL's Powerslide fin can. Uses a 54mm MMT as the body. Designed a nosecone w/ ebay (inspired by IPL). It's printing now. EDIT: The ebay sled is for my new Eggtimer Quasar. Starting build tomorrow! Woohoo!
On the other printer, I'm cooking off the Sapphire fins/nosecone that Chuck put up on Printables a while back. Added some centering rings and retainer.

Me like.
Sometimes (read: Most times), I can't leave well enough alone. I had some issues with the Sapphire Fins being really thing and warping (my issue, that I fixed with reducing bed heat). I increased the thickness to 3.18mm (1/8-in give or take a couple thousandths of an inch). I also have added some quality of life components to the build:
All that's left is:
- Fin alignment guide modified to accommodate the thicker fins
- Ejection baffle - I have used this lots of times in the past and it works really well.
- BT-50-18mm MMT with an updated retainer ring. This will accept an 18mm tube sleeve and slips right into a BT50
- Launch Lug
All that's left is:
- Screw eye
- shock cord
- Streamer/Parachute
- maybe a sheet or two of wadding just in case
- Paint/Decals
- Motor
- Park
what is this? Is there a link to the STL? I love the fin config.
Bearing lubrication tips.
I increased the diameter of the nosecone by 0.2mm to 25mm even. This gives me the best fit for Estes BT-50 tubes.

Well...it happened... I printed this.
And then had to do this....
But, luckily I had a spare hot end that been on the shelf for years... never thought I'd need the whole thing, maybe the thermistor or heater, but now I'm replacing the whole thing.

Nice!

The SpiderMax scratch build (there's a build thread on here somewhere) that I worked on last year suffered a broken fin - from the car ride home of all things. I originally printed the fins standing up so the layers make the fin rather weak. Last weekend, my oldest son decided that he wanted to build one so I fired up the printer and started printing another set of parts. I decided that after printing the fins, I don't like printing them standing up. I put them on the side (and used PETG this time), and they came out amazing. I had aggressive airfoils on the V1 fins but they wont work out for flat printing. I redesigned them in F360 with a round over and this is a decent compromise. I tried to break one and tweaked my wrist, so these should be able to handle an I-motor, if the flex doesn't cause the rocket to eat itself ::Note to self: Test this on the far-away pads::
I also resized the fin carriage from 29mm to 38mm. The Nosecone was reworked and I included the nosecone ebay. I also included a few parts from the 3D Menace project. That was nice not having to reinvent the wheel. I should have most of the parts printed out this weekend.
I also found some mailing tubes at Office Depot and snagged a couple. They are exactly the same size as LOC 3" tubes inside and out which was a nice find, so now I can get cranking on the Menace and SpiderMax Too.

Nice - build thread?
It's coming. I'm finishing printing the parts. I have pics as I'm moving, and I'll put them all together this week.
Sneak Peak:
Oh, you might have noticed that these are not the same fins as the previous post. This set is mine. The previous are going to my son. These have no airfoils baked in.
Printed more test pieces for an integrated thrust plate/54mm motor mount for a modular mount system I'm designing for a 2.6" body.
We had an impromptu park launch after lunch of some of my recent builds. We launched:
* WAC Corporal BT20: A8-3 (underpowered), B6-6 (Nice launch)
* RedMax Mini on A8-3: Great flight until the ejection then I had many fails including nosecone separation and body tube melted at top, finally landing right at the crash site, cracking the fin can when it impacted in the basketball court behind us. I know what the problem is, and have some ideas on improvements. Engineering is an iterative process
* BetaMax BT-20 on B6-6: Great flight with perfect deployment. Streamer was too short and it came in a bit hot and broke a fin. The baffle worked amazing with no damage to the chute, using no wadding or fire blanket
* Estes Alpha III on A8-3: Perfect up and down
WAC Corporal
RedMax Mini
Alpha III
Betamax
Also, I'm making tweaks to the SpiderMax Too (Big Red Max) nosecone. It was about 1mm short on the diameter and the coupler needed some tweaking. I will print them tonight and should be able to continue with the build this week.
Happy Easter to you all!

Modular sled for my 6” rockets with removable GPS section that has its own 1000mah lipo for long pad sits. Dual missleworks RRC2s with 3 independent pull pin switches on one pin. All stand-offs, mounts and wire pass throughs printed in. Happy with how it came out, cant wait to fly it.

I finished the Nosecone for the SpiderMax Too rocket. It was scary because the nose cone is 323mm and the gantry goes to 350mm. With the bed slinging around, I was afraid it would break loose even with the brim and raft I used. It hung in like a champ and came out perfect!

Today, I took a Chuck's Nike Smoke fin from Printables and printed it... just to see. It printed real nice. I thought about what I could do with that and well, that turned into this:
I had to modify the fin tab, since they fin directly into the can for this design. I also made it a little bigger. Its printing now. I'll have pics in the morning. I should have it mostly built tomorrow evening. Maybe even have some paint on it this weekend. When it's done and flown, I will post it up with the DRM and Goblin builds from my Extreme Series on Printables.

I hope to see that upload soon. I will surely print one.

I printed some avbay parts and conformal rail guides for some rockets I'm building. These were my first real prints on my new Qidi Q1, as well as my first ABS prints. They seem to have come out great.

changed the print head on our printer..
Waiting for co-workers to give me something to "try"..
also trying to get our older 'Makergear' printer up & running..

Oh, I made them in Fusion360/TinkerCAD. I have a couple of other models and used them as a framework. Nosecone and fin mods in TinkerCAD. The rest in Fusion560.
