So printed off a draft bracket to use to size the actual one. There's a couple of issues.....
In order to use the basket in shopping trolly mode it needs to line up about the bottom 2 holes on the basket in order to clear the 'top tube' when folded in to that config. It fouls the seat but this is easily remedied by rotating the seat.
The complication comes from the mounting holes are the same place as the bracket sides, so some cunning engineering solution required in teh design to mount it using the existing holes... or just drill some new holes (less inclined to do that as there's nice plastic coating on the cage
)
Another option would be a metal adaptor plate to offset teh basket up a bit more and allow side flange on the printed part to connect to the metal plate... There is a similar design already on thingiverse
Some thinking required on the ride to the pub and back tonight I think... I've done recessed nuts before but not taking the load this might take (though max weight for on the label is 5kg!)

My luggage block and bottom bracket spanner arrived today.
Luggage block was a nice simple job
I wasn’t happy with the bottom bracket, there was too much play in it so It needed adjustment. My trusty crankset removal tool made light work of whipping the crank arm off. I hate bodging with a hammer and drift so the proper lock ring tool worked a treat.
Everything was filthy, it’s probably never been off the bike, so I scrubbed and degreased everything and cleaned the spindle and crank arm, took the play out of the bottom bracket and reassembled with a smidge of copper grease.
Put it all together and now zero play, so had to have a cheeky beer to celebrate!

My plan was just to drill it and then use some oversized washers on the mesh part of the basket. Are you saying that the basket is too close to the frame, will it need spacers?

If using the current holes, they need to be aligned with the top half of the block- I guess my concern is around additional leverage on the 3d printed part. The part will have to be printed with the layers vertical rather than horizontal, that much seems logical so far (which was how the test piece was printed.)
I was initially thinking it would be as easy as something like this https://www.thingiverse.com/thing:2269441 but wanting to use it in shopping cart mode (seems daft not to!) means it does need the block lower on the basket.
If you are drilling holes, then this would work https://www.thingiverse.com/thing:1581133
If not, then it needs to be something like this one: https://www.thingiverse.com/thing:2479007
The latter was where I was in my thinking, the clamp that comes with it already has prefitted nuts in a back plate which I wanted to use, any holes to use them would end up on under the return edges of the bracket. I'll make a start on a model to see where exactly and see where I go from there.

If it’s any use to you, I can print one / all of those things for you and post.
A bit like my "proof of concept" bodgery?

You’re a star that would be really helpful

Which one(s) do you want?
Anything which you think would attach the basket below from Decathlon to a standard Brompton luggage block.
