A 3D printer-friendly recreation of of the Centuri PNC-89, the knockoff of the old MPC/AVI Mercury/Moon-Go space capsule with added on retrorocket pack improved by adding vent holes through the pretend nozzles of the main retros, and friend....

Daydreaming in 3D resin about Holverson Designs PNCs including a few appropriated from Centuri. Recreations of Centuri Fighter Fleet parts, a side project, and a recreation of the MPC/AVI Mercury space capsule. The Mercury capsule was modified with a retro that has a hole to accept an eye-screw.

A recreation parts set plus an original nozzle for the Centuri Orion (my all time favorite model rocket) and what an Holverson Designs/Fun Rockets display stand would have looked like if things had turned out differently, both printed in resin, plus a big filament printed side project for a friend.

MPC Moon-Go parts and Centuri Fighter Fleet parts recreated and resin printed. Plus what a Holverson Designs Tangent PNC would look like if I didn't have such wonky luck.

Resin printed nose cones of my own design for the Semroc Baby Orion and finally a good print of my recreation of the old MPC/AVI/Quest dress up kits with a PNC15 thrown in there for good measure.

I'm amused that they live in a bounce house. That use to be my favorite thing at the carnival back when I was a tween in the '70s.

Hoping that Merry inflates even bigger. Although she ain't bad now....

I found this curio in the basement while trying to organize it this morning. It's an Omaha Rocket Club banner from the early days of the group during the BAR summer of '94 before they merged with the local Tripoli prefecture and became THOR. It's a hand-me-down from John Carroll when he moved away.

I designed a new Holverson Designs nosecone this afternoon on a whim, the PNC14028, a double length parabola for the BT-5. Even if it's nearly 30years late to do the company much good....

I'm trying to do the recommended Darren T OpenToonz tutorial on YouTube but I'm stuck before I even start. My workspace is really different than his. I don't have the wonderful horizantal Timelind to click on and can't find how to set it up. I did find the Command Bar but it won't let me move it.

2/ Still burning off frustration over the animatics and not getting any help.

1/ Another visual portmanteau pun. I call this one the "Fire Hawk". It's with two great defunct performance cars from two great defunct car companies. I've been toying with this idea since high school. This is the first attempt where I've pulled it off.

3/This reminds me of why you haven't seen 3D printable actions figures of Flexia and friends for the past 12 years because the Poser and DAZ are impossibly awful and I'm trying to do this alone with no help.

2/I did this because the animatic is stalled again possibly until later to never. I started a tutorial on the software and immediately stalled out because my workspace doesn't look like his and I don't see any of the buttons that he's clicking on.

1/A little icon the I made up for "Skill Lever #6: Specially; RC Experience Required!" for a hypothetical Caliby kit-card. I wouldn't be surprised if this visual pun was done before, maybe back in the '70s give or take a decade.

Work in progress. About all I can stand for today. See if you can find a little creator's provincialism...

I hated them back when, and because, I was a Mac fanboi back in the Beleaguered '90s.

Good news: I got as much done in two days in OpenToonz as I did in two weeks in Krita.

Bad news: I'm stuck at not knowing how to select and remove the white around the tractor and loader. Please help! I hate how much of a vertical learning curve this stuff has.

I'm putting the final fillets on my Uni-Bird built from 1972 Centuri plans. I started assembling my Aerotech G-force that was given to me 25+ years ago.

sam the fan animatic updated now with sound
sam the fan animatic updated now with sound YouTube video by Doug Holverson

The Sam the Fan vanity plate updated with a FANfare by Pat Moriarity's son Jack. I'm letting my child of the '70s with Super 8 Sound animation teen dreams that didn't work flag wave here.

Chicspec loosing up from the retconned InterStellar OverDrive. One of Flexia's security officers. The closest thing Revellia has to a friend. And when Celandine wants to pretend sherif, he can alternate between deputy or One Eye Jack, the Baddest Bad Man from the Badlands....
