He asked me if I would 3D print scans of Neil Armstrong's glove.
The half scale glove is 6in tall and full scale is 12in.
My relatively thin hands were able to fit inside the full scale part.
Printed each glove in two parts. Filament deposition 3D printing process works best printing forms that start with a wide/thick base and get smaller/thinner as part goes up.
The inside of the gloves were also accurately scanned, and included a mounting collar at the wrist for joining to the rest of the spacesuit. So I split the model of the glove at this "wrist" point and that was the bottom of each printed part. Then bonded these two parts by painting with acetone and joining them.
It will take some sanding to reduce the layer banding created by the software and printer's difficulty matching the fine detail of the high-resolution scan.
The full scale glove is the heaviest and most detailed part I have printed so far at 17oz.
Small glove took about 3hrs to print and large glove about 30hrs.
Fun and cool, but not quick.

Both my friend and I thought that there was odd-roc potential for Neil's glove...
Put the glove on a couple existing rockets for fun pictures.
Inclined to make odd-roc just the glove with a minimal (black?) fin structure below it.
For this purpose, I would want to print the full-scale glove with the same detailed exterior, but thinner walled / lighter weight, and internal form modified for rocketry.

My first flight was the Seis: 24mm FlisKits Tres +3 motors.
Loaded with 3x D11-P + 3x D12-5 only half the motors fired for a hard recovery.
Clustered rockets and igniters flown today had been prepped a couple months ago, but due to a conspiracy of weather, technical and scheduling issues not flown until today.
Meanwhile they were exposed to some humidity and handling...
Rocket will be repaired. Said that too many times this year...

- lay two crossing layers of masking tape to cover gaps between motors but leave nozzles exposed
- fill each nozzle with BP
- lay a grid of quickmatch, with one end protruding to receive igniter
- lay two more crossing layers of masking tape covering all
After doing this more than a dozen times, can complete all motor prep in about 1.5 hours.
Then at the field, final prep time is similar to a single engine flight.

Weather was moderate, 50's with very light winds for most of the day.
First up was the Pink Flamingo on a CTI G68-6 White.
Put a pink flamingo adorned nose cone on the Canadian Arrow and launched from a HP pad just in case...
Flight was quite stable to start, with a slight wobble as it was arcing over.
First flight for this combination of flamingo NC and rocket body.
Used the JL chute release, but it was not needed with these light winds.
As a result of packing the chute too tightly and setting the chute release too low, the recovery was fast and one fin will require modest repair.

The Bomarc is quite low and slow, helps keep it in great shape after 6 flights
May load central E9-6 motors when conditions are favorable going forward
