My dad had a cabin bag with a very flimsy handle that broke during regular use.
We looked for a replacement online but we were unfortunate, mostly because the telescopic posts used are oval-shaped and tilted inwards.
All replacement parts we could find did not fit that design.
I have a 3D printer at home and he just happens to be a retired AutoCAD wizard, so he designed model.
It was a really heart-warming moment of father-son collaboration to me. Good core memory.
With luck, you may also happen to benefit from it.
We printed this on PETG to make sure that it last while exposed to the elements or the rough rides it may get at the airport (at least it is sturdier than the original)
It works as a full replacement, so you will still be able to use the button the engage and disengage the locking mechanism that controls the telescopic posts.
The broken handle had a spring that used to prop up the button on the handle. If you have salvaged that, you can make use of it on with this replacement part, but it is not actually required. (we could not find ours and it worked just fine)
To put the piece together, you may have make use of an electrical drill to make some guide-holes and 4 screws (if think M3 would do).
Maybe some superglue for good measure.
Props go to my dad, Renato.
