How long do 3D printed parts last?

Posted on February 5, 2023 by paulwallich

One data point to add to the world: in a dishwasher that’s used every day, about three years, maybe more. Back in 2020, I fixed the bottom rack of our dishwasher by printing some pegs and new wheels out of … Continue reading →

Ok, this is actually useful

Posted on January 13, 2021 by paulwallich

And it only took me 9 years to notice. It’s an openscad script for making keyboard feet. Thank you. Not such a big deal at home, but at a school with donated computers of interesting provenance and a couple dozen … Continue reading →

Something actually useful

Posted on March 3, 2020 by paulwallich

Our dishwasher is getting to be a certain age. And the plastic parts are showing it. Especially after one of the youth tripped over a cat and onto the bottom rack. When the wheels fall off they have a really … Continue reading →

Let There Be Light

Posted on December 4, 2019 by paulwallich

I remixed an old openscad christmas tree design to include space for a coin cell and an LED. Coincidentally I have a bunch of green LEDs lying around — their light gets through the plastic a lot better than the … Continue reading →

Vindicated

Posted on June 12, 2018 by paulwallich

About two years ago, for no really good reason, I designed a 3D-printable setup for coupling those standard gearmotors to Lego bricks and axles, and posted it at Youmagine. Hardly anyone liked it or downloaded it. Then, last week, Adafruit, … Continue reading →

Burning down the house by remote control

Posted on March 9, 2018 by paulwallich

A few weeks ago I blew up my Octoprint installation by adding and deleting too many extensions at the same time. Before reinstalling, I thought it might be a good time to upgrade a bit.  So now there’s a cute … Continue reading →

Lubricate your fans

Posted on October 28, 2016 by paulwallich

(tl;dr: if you have a fan that cools your hot end or heat break, lubricate it. It may solve some problems.) It’s a good thing I splurged on the dual extruder for my printrbot way back when. Not that I … Continue reading →

The autopilot conundrum

Posted on May 11, 2016 by paulwallich

This morning I stopped by a local school where some of the kids had crowdfunded a 3D printer (a printrbot Play) to see if I could help them get it working. I seem to have become the town expert, which … Continue reading →

The gift that never ends

Posted on March 22, 2016 by paulwallich

This winter I had the idea of donating my old Cupcake CNC to the local library. Get it out of the basement, I thought. Put it where other people can use it. Find a home for all that extra 3mm … Continue reading →

I like Octoprint

Posted on February 15, 2016 by paulwallich

So I was sitting upstairs where it’s warm, instead of down in the cold basement, and suddenly I had the idea to print something I’ve been noodling on for a while. Click. Click. Click. Move the Octoprint browser window so … Continue reading →
