3d printing – Greg Horn

Over engineered Bracket

What do you do when a $0.05 part breaks on your IKEA coffee table? Order a new one, right? Of course not! You learn how to use your favorite CAD software’s topology optimization package! The algorithm that is used by most of the CAD packages is called SIMP. The important thing to know is that…… Continue reading Over engineered Bracket

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

Epoxy drip catchers

I had a problem with resin and hardener dripping onto my workbench resin drippage I solved it with an overengineered dripcatcher

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

Multi-material printing

I helped put together the MMU2s for the work printer. It is very painful and flaky and I wasn’t able to get consistent results. The dream is noble but hobby-level tech is not there yet. The Prusa XL printer is supposed to have multiple print heads via a toolchanger, maybe that will advance the tech.…… Continue reading Multi-material printing

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.
