A short story about a drawer slider bracket, 3D printing, and the internet

Among my numerous hobbies is 3-D printing. My wife bought me my first “put-it-together-yourself” kit back in 2016. Since then I’ve upgraded to a Bambu Lab X1, which is as close to a home appliance as 3D printing has ever been. It literally has never failed me short of my own errors.

Recently, my mom called me up to tell me that multiple drawers in her kitchen cabinets were broken. The rails the drawer slides along had fallen down, and the drawers were no longer horizontally level. Her husband took one apart and found that the bracket that holds the rail to the back of the cabinet had broken.

She looked online to see if she could find a replacement part, but was unsuccessful. Knowing I have a 3D printer, she asked if I could print a replacement. Always eager for a fun challenge (and because I’m a good son), I said sure.

Before I started measuring and modeling the part, I took a look online myself to see if I could find replacement parts. Sure enough, there were other people were having the same difficulty sourcing a replacement part.

So I started measuring and preparing a model.

A few minutes into doing this I thought, “Wait a second, I wonder if someone else has come up with the same solution and already made a model?”. Guess what? Someone had!

In 2017 bmonnin created and uploaded their model for others to use. They had the same problem my mom had!

“I had several brackets that support the drawer slider on my kitchen cabinet drawers break. After looking around at several different big boxes and online I couldn’t find the same bracket anywhere.

So I got to printing.

A few minutes later, a solid replacement for the part was born.

I printed it in red because red makes it go faster

There is a slight, almost imperceptible, difference between the original and the model. The lip that holds the rail in place is on both the top and bottom in the original. Assumedly so the manufacturer could print one mold and flip it for either side of the drawer. bmonnin’s model only has the lip on one side. They provided a mirrored version though, so all is well!

Since my mom needed more than one, I set up the X1 to print enough for all her drawers.

A few hours later, and less than half a spool of filament, I was done.

The next time I saw my mom, I handed a box of brackets off to her and Ken. A few days later she shared these photos.

Huzzah! A resounding success. I hope they last as long as the old ones (26 years, since the house was built).

This is one of those mundane, but also incredibly interconnected, stories where technology – combined with the social aspects of being able to share information easily and freely – come together to create a tangible solution to a problem. A small problem in this instance, but I think an example of how even larger problems can be solved when we think and work together.

Michael E. Koerner

Michael Koerner was my dad. That’s hard to write. “Was”. There’s not much new to be said about the death of a loved one after centuries of human experience, especially those who are the closest to our hearts. But that’s what I’m going to do, because this is my dad. And I loved him.

August 6, 1951 – January 3, 20241

My dad and I in San Diego, 2022

My dad was born in St. Louis, Missouri on August 6th, 1951. The internet says it was a Monday, and hot (92ºF). He doesn’t remember that. He grew up in south St. Louis City, Affton, and was the second oldest of four children. His parents worked hard to provide a safe and loving home and they did. Something that we Koerners continue to strive for today. He had a typical lower-to-middle-class upbringing. Running around the neighborhood getting up to no good, cooling off on the porch roof on a hot summer night. Hanging out with his younger brother Greg. Grandma, Georgia, never learned to drive, having access to public transportation – and Grandpa, Christ, did own a car and would take her wherever she needed. They both worked and cared for their children.

After high school he tried college. Forest Park Community College, but ended up joining the Navy. He spent a few years aboard the USS Reasoner. Even after only serving four years, he had a lifetime of stories to tell. About the people he met and befriended and the places he saw. Southern California – where he met his first wife and my mother, Carla, Vietnam and the Philippines, Washington state and even a little bit of Alaska, by way of motorcycle.

Oh I should mention motorcycles – or really my father’s love for anything with wheels and a motor. 

A car aficionado since childhood, my father could look at nearly any vehicle on the road (or often in a parking lot at a local car show) and tell you numerous indelible things about the construction, performance, and culture around it. If it has a 404 (a size of motor), but came from the factory with a 306, he’d know what make and trim and year and…well, you get the picture. He was at every Easter Car Show in Forest Park for the last 30 some odd years. Even the little local ones every month, April through October.

Mike, sorry, Michael – he was big on proper names2, not that he ever chided anyone for shortening them – spent his forty-something years of employment working in warehouses and mailrooms in higher education institutions. First at Washington University’s Central Stores, and later Saint Louis University. He worked hard and smart. Never making a trip back-and-forth empty-handed.

He defied the oft too common stereotypes of a motorcycle-riding, blue collar worker by being a fan of the arts. Which makes sense when you work for universities I suppose. Nah, my dad was just a voracious learner, a critical thinker, a common sense maker. A set of skills that continue to be passed down.

He was kind and loving. You couldn’t get off the phone without saying, “I love you too”, and even in my teenage years – and much to my chagrin – I always appreciated the affection he shared with me and many others. He showed up so many times throughout my life – all the way up until the end. He always told me how much he was proud of me. 

He adored being a dad and eventually a grandfather, lovingly known as Pop. Pop attended every dance recital, choir and orchestra concert, soccer game, and numerous other events his granddaughters do. Most recently he helped his oldest granddaughter Kari complete her Eagle Project. He welcomed my wife of now 20 years, Jackie, with such admiration and care that she was taken aback by the first hug and has loved every one since. 

Pop and the family

My dad was an avid reader. Of sci-fi, westerns, fantasy – anything with a good story and quick-witted dialog. He even started writing a few of his own stories, unpublished, but loved. 

He loved the movies. Film was a big way he and I bonded. Sharing the experience of being in front of a big screen and kibitzing afterword about the plot and characters and special effects. Oh, and going back to the mistaken stereotype, my dad loved the theatre. His favorite show was Mama Mia. A musical based on ABBA songs! I think he’d seen it enough times that they could have asked him up on stage to fill in as an understudy. We loved the Fabulous Fox Theatre and the hundreds of experiences of a live performance. A many blessed memories with the Vogelsangs (his godmother Martha and cousin Pat) and many others.

Education was crucial to my father. Working at universities (and being aware of the world) he always drove home the importance of being open-minded and continually learning. He worked these physically demanding, not very well paying jobs, so I could go to school. My going to college was very important to him – that I could have, and succeed, in a life better than the one he had. 

They say a way to a man’s heart is through his stomach and that has never been more true than with my father. He loved to try a new place to eat, to take us out for a casual burger, and to enjoy a home cooked meal. He stuck to the more traditional fare, but he never turned down trying something new. 

Never quite a trendsetter, my dad is proceeded in departing this life by his parents, Georgia and Christian, his brother, Gregory and sister, Barbara. He leaves behind a sister, Helen. He is proud of his son Christopher, his wife Jackie, and their two daughters, Kari and Kori. As we were of him.

To tell a story is to have one’s memory live forever. Please watch a film with a loved one and tell a story or two. Pick up a good book and read it aloud to someone. Travel. Go someplace new, even if it’s just a restaurant across town. 

If you’re interested, my dad asked that donations be made to the Ronald McDonald House Charities of St. Louis.

He didn’t want a funeral or a burial ceremony. “None of that dreary stuff”, he said. I don’t think he’d want a traditional obituary either, hence, the more casual and conversational tone in this one. Something I think my father was known for. If you want to pay a visit, he is interred at Jefferson Barracks National Cemetery.

A gathering will be held in the near future to celebrate his life. Where we can come together and share stories of him.
