CAD – Greg Horn

First CNC project

First project! A little shuttle-inspired spaceship carved from pine. CAD I whipped it up in Fusion 360 with the sub-d modeling environment. CAM I used Fusion’s built-in CAM package. Adaptive clearing pass (1/4″ flat endmill) Morphed spiral finishing pass (1/4″ ball endmill) Cutting Result

3d printed airplanes

I printed a batch of airplanes for co-workers. I spent a while trying to optimize the size without increasing printing time too much. Eventually I pitched it up 15 degrees and turned it diagonally. Here’s an earlier slice:

Dice shrine

I build some dice holders to improve my DnD game. I’d been making some bad rolls so I built these devices to give my D20s positive or negative feedback. Dice shrine (right) which charges up good luck.Where there is the carrot there must be the stick – if the dice performs poorly it goes in…… Continue reading Dice shrine

I left the ball at home. Well pajamas finally had too many holes in them. They would rip when…… Continue reading Bowling pajama micarta

3d printed pencil holders

I printed some hex-grid pencil holders to challenge myself in CAD. I got it done but I still don’t know of a great way to model these. The end result hot off the printer

SLA printing

I’ve been doing some resin printing over the last year. Here are some examples

Sculptures

I’ve been doing a series of sculptures. Originally the motivation was to build a webcam holder so that I could monitor 3d prints: The original one The second one was more organic and had mostly parametric features with one sculpted feature: The next one was almost fully sculpted. A mechanical engineer at work asked if…… Continue reading Sculptures

Extruder windmill

I made my own extruder windmill based on this post from Prusa I modeled it in Fusion 360 and printed on a Prusa Mk3s

Doorstop

My lockdown office has a door to the deck which I like to leave open when the weather’s nice. The doors were banging around in the wind, and since you can’t get doorstops or toiletpaper during lockdown I made my own. They work OK.
