Just wanted to share a fun little project that I finished this week: a 3d printed frame bag for my gravel bike.
Bag is made of 95A TPU, printed in multiple pieces and glued together with LocTite fabric and vinyl glue. Cover is glued on with magnets holding the opening closed.
This is a picture from the initial print, before putting the cover on. I will post more of the finished bag when I get home.
Love it! I’ve had a similar idea, but it remains just an idea, and would not have been nearly as well executed as yours.
Would love to hear more about your process if you don’t mind sharing!
I like the shaping around the tubes, but that automatically means it’s not a universal design.
I assume the need to glue is a size-based thing? Seems counterintuitive otherwise…
Second vote for awesome! I’ve been thinking of a Swat Box style bag for a Tarmac SL8.
What size is your bike?
The bike is custom, but would be a 58cm or L to XL in most sizing.
I wanted in integrated look, so definitely not universal design.
I originally split the shell into two halves to try to avoid using supports. I don’t have a ton of experience printing TPU so I didn’t know how well they would be removed.
Having built this one, I think I could simplify the process quite a bit knowing how the TPU prints.
Not too sure what to say about the process.
I used On Shape for modeling. I have been using it for a while for various other projects and I really like it. It is free to use and browser based, so I can use it while I am at work, haha. They also have a pretty good tutorial and education section.
I mostly just fumbled my way through the process, just figuring it out as I went along. As I mentioned in another reply, I think I would be able to make another one much easier.
The bike is all round tubes, so that made the design easier. Also, it is a custom frame, so I have my design drawings to work off of for getting the angles just right.
