3D Printed BMX Seat Post

April 12, 2018

Jonny Lee 3D printed a Pivotal seat post for his bike…

It looks like Jonny Lee has decide to try his hand at 3D printing a Pivotal seatpost for his bike. This one might not seem super complicated, but it ended up taking a few goes before it worked out the right way. Hit play to see some footage from the printing process, along with some riding footage he got in after he got the post on his bike. It’s a fairly basic part that doesn’t see a ton of abuse, but does get some wear and tear when riding, and it looks like it held out fine.

“Printed using the Monoprice Maker Select V2 (trash) with a metallic PETG filament. (not trash, but with this printer becomes trash) It’s supposed to be pretty strong stuff, so I hear.

Carbon Fiber BMX Hub Guards?

April 5, 2018

Jonny Lee is back with another custom creation. This time around he tries out carbon fiber hub guards…

Lately when we see a video from Jonny Lee, he’s cooking up a new 3D printed part for his bike. We’ve seen him do a handful of really cool projects, and now he’s going to venture out a little more and try out carbon fiber as well. Jonny recently started testing out a carbon fiber hub guard that starts out with a 3D printed layer. These two videos (the 2nd one below gives better detail in my opinion) show how he made the hub guard and a little testing he was able to get in despite bad weather. These are just a few basic concepts, so we have a feeling we’ll be seeing more from this project soon. Either way, it’s pretty cool and appears to work! Take a look!

What do you think? Have any of you tried to make anything with a 3D printer or something out of carbon fiber? Let us know what you’re thinking or what you have tried out in the comments below!

3D Printing BMX Parts – Questions and Comments

March 24, 2018

Jonny Lee has been pumping out a lot of 3D printed BMX parts lately, so he decided to do a video answering your questions.

If you keep up with the site, you know we’ve been sharing a bunch of videos from Jonny Lee showing his different 3D printed BMX parts that he has been making. After all the videos, Jonny has been getting a number of questions about the different things like the liquid he dips the parts in after they are completed, why he doesn’t run the parts on his bike full-time, how the weight compares to aluminum or chromoly parts and more. Jonny decided to do this one while out for a brisk cruise on his motorcycle, but there’s a good look at some of the different parts he has made over the past few months. If you want to see everything he has created, check out the links below!

“Thank you to everybody who comments or leaves feedback, KEEP THE QUESTIONS COMING!
It was so cold, so bleak. I tried to hide it. It made it super hard to think and clearly convey what I was trying to say, but I didn’t struggle through this ride to not upload the damn video.” – Jonny Lee

3D Printing BMX Hubs?

March 19, 2018

Jonny Lee has taken a crack at 3D Printing his own front hub…

https://www.youtube.com/watch?v=d-NEnvO1MlU

Here’s the latest 3D printed creation that Jonny Lee whipped up in his printing lab. This one didn’t really start out as expected, but after some tweaks and changes, it looks like he was able to make a 3D Printed front hub that worked. Here’s a shorter than usual video showing the process and a little bit o the testing to see if it held up! Take a peek!

“Welp… this was interesting. This is another one people have been asking for since I started the 3D printed parts “series.” The first hub broke immediately because I didn’t provide any lateral support whatsoever, it slipped my mind I guess. I also made the body super thin, so on the second try i just beefed it up a little. The part of the video you don’t see is the two hours of me slowly working up confidence because of how scared I was to try any real tricks. Hope you guys like this one!” – Jonny Lee

3D Printing BMX Grips

March 7, 2018

Jonny Lee is back with the 3D printed magic… This time he 3D prints molds for BMX grips!

Over the past year, Jonny Lee has been experimenting with 3D printing different BMX parts. Today he dropped a video showing us how he made his own BMX Grips by 3D printing his own mold. This video shows you how the mold was made, minus the CAD drawing part that he usually shows in his videos, along with some footage of him riding with the grips. Hit play and take a look!

If you think that was cool and want to see some other 3D printed parts that he has made, check these out…

“This took a lot longer to make then I had anticipated! I’ve wanted to make custom BMX grips for a while, I finally got it figured out so here you go! They turned out great and I have every ambition to keep riding them for the foreseeable future, encase you were wondering.
Let me know in the comments what you want to see next!” – Jonny Lee

How To 3D Print BMX Bar Ends

November 28, 2017

Want to learn a little about using CAD? How about 3D printing? Jonny Lee is back with a video to show you how it’s done.

It has been a little while since Jonny Lee put out a video showing you his 3D printed BMX parts, but he’s back with a real rad one for you today. This time around he has decided to 3D Print some bar ends, but instead of just printing it and showing you the end result, he decided to also teach you how to use Free CAD software to design the bar ends, then take that to the 3D printer and then get a look at the end product. This might be a little over some of your heads, but if you just watch it, you will pick up a few things along the way. Real cool.

“In today’s video I walk you through how to design a pair of BMX bar ends using the free 3D modeling software, FreeCAD.

3D Printed BMX Pedals?

August 26, 2017

It’s time for Jonny Lee to experiment with 3D printed BMX pedals…

Over the past few days, Jonny Lee has been giving us a little look into his latest 3D printing project, which he has decided to go with some BMX Pedals. This one turned into a 3 part series that spanned a few days from the initial design and testing to make sure it’ll fit a spindle and bearings, to getting the kinks figured out with the design, the 24 hour print time to make both pedal bodies and then getting the pedals dialed in and tested out. Up top is part one and below you can find part 2 and part 3 showing you the entire process. If you just want to see the finished product, skip to part 3 below!

3D Printed BMX Pegs?

August 13, 2017

Jonny Lee has been on a mission lately to see how many 3D printed parts he could make. First, he made a 3D Printed Sprocket, then he went and made a 3D Printed Stem. It looks like he didn’t stop there because he has cooked up a set of 3D Printed pegs. Well, they’re actually peg sleeves. Check out the video to see the pegs, along with how he got them to work with the chromoly inserts from another set of pegs. After that, he puts them to good use on a flat ledge / rail setup he has in his driveway. There was some speculation on how safe / durable the sprocket or stem was, but we’re pretty sure everyone who rides plastic pegs will want to try this one out.

“A lot of people were asking for me to 3D print pegs/peg sleeves… so here you go!” – Jonny Lee

What else would you want to see for a 3D printed BMX part? Pedals maybe?
