The Coolest Homemade 3D Printed Bike Parts!

The Coolest Homemade 3D Printed Bike Parts!

Over on the GCN App we’ve seen a lot of 3D printed bike parts, and we thought they were so cool, we’d dedicate a whole video to some of our favourites! Alex takes you through the basics of 3D printing, and some of his top 3D printed hacks!

    I clicked on this thinking it was a video from one of my 3d printing channels. I might print a dropper post lever when I get a dropper post for my hard tail. I’m inherently kinda cheap and currently poor. Stupid pandemic.

    I made some aero boxes that hold hydration bladders under the aerobars and in the frame triangle of my tri bike. I mix my nutrition as a drink and can fit enough for the bike leg of an Ironman. I don’t have to mess with refilling a reservoir or shuffling bottles around. The straw is held in place so I only need to leave aero position to maneuver or stretch out. Plus it looks cool.

    Here is my first attempt at 3D printing some bike parts. https://youtu.be/mc-1zr1Nm4M

    Can you 3D print Zip Ties?

    Question from Si

    😏😆😁



  5. Chris Pownell on September 4, 2022 at 1:50 am

    What software does everyone use to create things like the GPS mount?



  6. Five Minute Velo on September 4, 2022 at 1:53 am

    Here’s my second video of a 3D printed seat clamp cover. https://youtu.be/4Z26S2GoHIg

    Huh?, lots of info, but what is The best tire for a rough roads and spayed?



  8. Fiete Ferrum on September 4, 2022 at 1:54 am

    Pro tip from an engineer working for plastics department at my university, to make a part stronger increasing the wall thickness helps more than increasing the infill percentage. The part walls are in direct of load most of the time. Great video, I printed spd-sl sneaker plates for casual riding, they work great so far ✌️



  9. Dundee Dideley on September 4, 2022 at 1:56 am

    give us a best 3d printed parts competition



  10. chills996 on September 4, 2022 at 1:57 am

    Best 3D print I’ve used so far is a Shimano Hollowtech crank remover tool… took mere minutes to print and is seriously useful. Nice vid! 🙂



  11. James Lee-Pevenhull on September 4, 2022 at 2:00 am

    3D printing IS NOT wrought or drawn. You take the risk.

    The drawing file for the 3D print product is best done on a package that has finite element stress analysis. You need the Youngs moduli of elasticity and rigidity for the material you are using.
    Remember with 3D printing, there is no polymer grain structure.
    3D printing is OK for model aeroplane wing and fuselage parts, because there are no human passengers at risk when the thing hits the ground.

    3D printed metal parts as as good as castings. No structural strength.



  12. Doxie Lain on September 4, 2022 at 2:02 am

    If you want strength, go for petg. PLA gets brittle from uv exposure after awhile.



  13. bele13 on September 4, 2022 at 2:04 am

    How was this not hosted by Si?



  14. Ed R on September 4, 2022 at 2:06 am

    Just spent a satisfying afternoon in my workshop making a replacement part for my shifter using only hand tools. No 3D printer required and it’s made of aluminium instead of plastic.



  15. Henry Kloepper on September 4, 2022 at 2:07 am

    I’ve been printing customized gps/light mounts this week to replace the ones broken in a wreck with a Jeep last month that totaled my Ti Salsa La Cruz. Handy tool if you have the chops to learn CAD/Cam software.



  16. Drew Felix on September 4, 2022 at 2:10 am

    Im trying to get the shop I work at to get one!



  17. Tim Angus on September 4, 2022 at 2:10 am

    What’s the deal with comments getting auto removed on GCN videos? Like what are the rules?



  18. R Plumb on September 4, 2022 at 2:11 am

    Uh oh! I thought about printing headset spacers a couple of years ago, but decided it wouldn’t be safe. Though they’re not specifically load bearing, I think there’s probably too much force going through them as you ride. PLA probably wouldn’t be safe over the long run. Might be wise to ask an engineer though. 🥺 Just think of what would happen to your steering if all of a sudden one of your headset spacers disappeared.



  19. bonbon on September 4, 2022 at 2:12 am

    It is a pity that Si didn’t Si show up in this video him being GCN’s 3D printing expert 😅



  20. c on September 4, 2022 at 2:15 am

    I need a life size, 3d printed Ollie.



  21. FLG8R on September 4, 2022 at 2:15 am

    i designed and 3d printed custom camera mounts for the GoPro Hero Max so that you have that properly stitched, detached view; fasteners for the Garmin Varia STL515 that uses zip ties instead of the rubber bands; storage holder for CO2 cartridges + inflator, etc. … stuff like you said that aren’t load bearing … a useful tool(s) for designing these items are a vernier caliper and Autodesk Fusion 360; i prefer PETG filament instead of PLA; PETG is UV resistant and is the medium between PLA and ABS. I’m just an engineer that loves cycling also … you can see some videos on my channel as examples



  22. Rundervinkje on September 4, 2022 at 2:20 am

    I made a little clamp that has the functionality of a hand brake. When i come home from a wet ride, i can clean the chain without it wobbling and then put it in the garage to dry fully. Very handy tool. Also, spacers for your discbrakes when you remove the wheels.



  23. Alan Daly on September 4, 2022 at 2:22 am

    More videos to follow this idea though would be good. Would be useful to discuss pricing. Leaving aside machine cost how much does it end up costing to make that part. Alex mentioned in the part he made for his bike it took several attempts to get it right so overall what did that part cost and was it worth it in the end.



  24. Chris van Buggenum on September 4, 2022 at 2:25 am

    No load bearing? But it worked so well for the Australian track team.



  25. John Muther Colonel, Ret. on September 4, 2022 at 2:27 am

    More of this please!



  26. Manuel Deubler on September 4, 2022 at 2:28 am

    My personal favorite 3D bike thing is a piston advance tool by Murchderlurch on thingiverse. This tool is base on a Shimano bleed block with a cut out on one side that allows you to advance only one piston for cleaning.



  27. Peter Sauer on September 4, 2022 at 2:29 am

    Is that a egg cup on the table 🤔



  28. TM on September 4, 2022 at 2:30 am

    Well we can make our own design of water bottle, bottle cage,chain guard and maybe fenders with 3d printer.



  29. Nic Christie on September 4, 2022 at 2:34 am

    My sons just got a 3D printer… I may start to take interest 😂



  30. Robert Tell on September 4, 2022 at 2:36 am

    I imagine Si watching this video screaming Hack every 30 seconds.



  31. Sam on September 4, 2022 at 2:37 am

    Alex, how can you talk about cool 3d printed parts without sharing STLs? Collecting STLs is as much a part of 3d printing as collecting spare bike parts is to cycling.



  32. okleydokley on September 4, 2022 at 2:37 am

    I have a bunch of designs for bike tools on Thingiverse. You need to know the limitations. 3D printed plastic is not as robust as injection molded and typical plastic like PLA will warp in sunlight.
    Ideally, you need to use Nylon for parts, which means you need a far more expensive printer.

    But for shims, saw guides, headset presses, stands, it’s OK.



  33. Ronnie Irawan on September 4, 2022 at 2:40 am

    You guys use a new camera?



  34. Andrew Kay on September 4, 2022 at 2:40 am

    I asked for this video from Alex over 6 months ago! Glad it came about



  35. TRiX on September 4, 2022 at 2:40 am

    I made a customized phone holder on stem – when it is well made then it works like "click-in slide-out". It make me happy every ride. 😊 I developed specialized slicing technique / process, so i can made really light and functional 3D parts (with customized infill).
