Flatpoint Tower mini-ITX case

Positron · July 4, 2025

I wanted a 3D printing design challenge. Something hard for me to do.
I am a Graphic designer, Industrial designer, Mechanical Engineer. {retired}
Been a designer all my lifetime, but I'm still a noob to owning a 3D printer.
My brother gave me his AnkerMake M5C for my Birthday.

My idea was for a mini PC case that can hold a SFX PSU and a midrange GPU.

For Mom. Her PC is ancient, she complains, but won't let me buy her a new one.

The 'Flatpoint' name was the High School on the Comedy Central show 'Strangers with Candy'.
At first I made a vertical chimney tower config. It was too tall. I had to flatten it out... led me to name it Flatpoint Tower.

I designed 3 other prototypes and tossed them for not being good enough.

It was hard to make a small PC with a BIG GPU in it look small. Some solutions were too ugly, too weird, too big or boring plain boxes that didn't work out.

I kinda like how version 4 turned out. It's about the size of a Xbox 360. Looks good. Works good. A nice balance of Art & Engineering.

The criss-cross tape design was inspired by a Van Halen poster on Tony Hawk's pod cast with DEVO.

The case took me 3 weeks to design. I had to do a lot of research to get the screw holes in accurate locations. and a lot of experimental layouts to figure out the best position for the components. Then I had to figure out how to cut a 350mm case into 6 x 220mm bed sized chunks. One of the chunks is an option to fit a micro-ATX motherboard in the case. It has No room for a GPU & No PSU and HDD brackets. A bare empty test bench version of the case.

Flatpoint took a week to print and assemble. I used nearly a full roll of Inland Micro Center Shimmer Red PLA filament. I was taking my time to make sure I did everything right. Because the print uses over 900 grams, I had no margin for error to mess up a chunk and re printing it. Most of the chunks took about 15 hours to print. I was very happy that the chunks lined up well when I epoxy glued it all together.

I Photoshopped the fake motherboard and GPU prints to be exactly actual size.

One minor fault is the front is about 1mm wider than the back = that is why the plexiglass top panel is bowed.

It's too hard for me to risk cutting a little bit from the edge of the acrylic without damaging it.

Other than that I need to build a real PC in it to enure that my engineering is sound.

Perhaps Alex and Linus can finish where I left off for content?

Anyone can modify my design to suit their needs. Or more likely, fix my mistakes.
