That looks really interesting and useful. Question, do you have any concerns with regards to the durability of the plastic created by 3D printing, under the kind of stresses (vibrations, hits from the road etc.) it experiences in such an application? Or have you tested that kind of thing before and found no issues?

The PLA is pretty strong, but with some flexibility, so it should hold up ok. Its slightly offset from the fork, so when i make one for the other fork I will try to overcome that which should give further stability. I plan to field test it at the weekend (although not carrying much weight). Once I have one for the other fork i can run them loaded up with weight.

Cheers, definitely interested in your findings. I think 3D printing is really powerful especially for this kind of application, and you can make exactly what you want and need...

A friend helped with the actual designing, as it would have taken me days to do it myself. Print time was ~10 hrs, cost in materials is a pound or two.

Sell a pair to me!

Lets wait and see until after I field test them......

Okay. I'm first in line though 🤠

Edit: Great work obviously, I should have said that first before demanding some

2L cider bottle = 2kg (ish) plus shock loading.
With things I've printed there have been issues with PLA layers separating under load - if this works I'd be very interested in knowing the print settings. I really do want this to work.

Got an approximate weight? I guess that would be the main reason to go that way instead of alu.

Not to hand, another one is printing overnight so can let you know. 2l of cider is ambitious, but I would think it will carry at least 1l no problems.

Cheers

I had a Gopro / Cateye adapter printed a few years ago in SLS PA (I think) and it lasted a weeks before ejecting my light across the road. I'd be very wary of putting 2kg on that!

It's probably worth reminding ourselves that although 3-D printing has been around for more than 20 years (having only recently become affordable), it has previously appeared centre stage as Stereo Lithography and Rapid Prototyping (amongst other monikers).
I'm not convinced that the materials currently available for 3-D printing (especially when it comes to plastics) necessarily have the properties one would choose were one doing a production run using conventional injection moulding techniques.
Where 3-D printing has the edge over conventional moulding techniques is
A) The ability to quickly produce low quantity prototype forms without having to resort to expensive tooling, and
B) The ability to produce forms which would otherwise be impossible using conventional tooling.
I don't think 3-D printing (where we are with it today) was intended for producing stressed components, which rely on the properties of their material for their robustness and performance.
That, I think, is yet to come.

My partner and I are into claywork and make decorative and functional ceramic pieces. It's only a hobby but we just got our first kiln after moving into our own little London sized Studio last year. The future is bright... :)

(will adding pics later from the pc)

If you're feeling impatient, there's a chap up in Scotland producing something similar and selling them through another chap in Scotland: https://backcountry.scot/product/dewidget-strap-deck/

I believe he has them printed at Shapeways, or at least he did for a while. With Shapeways’ nylon prints I’d be quite confident they’d hold up to a fair bit of abuse. Though do note that his design doesn’t have the little shelve at the bottom, probably with good reason.

If CAD skills are the limiting factor I’d be happy to draw something, the Shapeways prints aren’t going to be cheap though.

Great, looking forward to seeing your stuff!

Sounds about right.

While the shelf seems like the obvious solution, I'd expect in typical UK conditions it'll fast fill with mud (even with those drain holes), especially if used under the downtube and that is going to be heavier than intended and pretty grim. I think the 'lip' design other manufacturers go for (thinking King, Salsa etc) paired with a supported bag is probably the way to go if you need the extra support.

I'm pretty sure Bentley Components helped him with the prototyping.

As it happens, I have something currently drawn up on Fusion. I threw it into i.materialise for a quote: £12.42

Can I buy a few of these off you?!

Mine was about £3 in material costs. Compared to £35 for a salsa everywhere HD. If mine fail then I'll buy those.

I'll make a couple of bags tonight to go inside them and see. I don't think filling with mud will happen but yeah, the 'cup' thing on mine is probably overkill.

Carrying lighter things on the forks makes sense from a steering/handling point of view with heavier items in a frame bag or behind the seatpost.

Yea man. I made up a couple dozen, hoped the forum might be interested. Happy to send you a few for suitable forum donation. I still owe a forum donation after @Vince ’s generosity a week or two back.

Send me a message and your address to post to, and let me know how many you want.

Awesome, PM incoming.. #spiritoftheforum #weareallcunts

hoped the forum might be interested

I can't think why you might imagine there'd be forum interest for something like that. :)

I mean, it's not as if there's a history.
