    Compressor such as a local garage car tyre inflator - ideally with 'free air' and staff that know you.

    Compressed air > partial vacuum (5 bar rather than 0.5 bar) but watch out for flying debris such as rust, brazing flux, etc. as well as the bit that rattles.

    Mine was from Kowloon via eBay - MrsE refers to it as a tenner ukulele (£) in spite of it being soprano sized. It's my first ever 'musical' instrument - I suspect a 10yo will learn better than a 59yo.

    My most recent project. While waiting for stain and varnish to dry, I printed replacements for the fret board, nut, saddle, bridge, strap buttons and tuning peg bushes, all of which were included in the kit but of poor quality.

    Well done for giving it a go and sharing the outcome! You'll now get all sorts of unsolicited advice and unwanted suggestions: here's my probably unwelcome contribution.
    Change the orientation so the layers run vertically. Probably need to support 'everywhere' which will then need finishing.
    Also increase the skin thickness until there is no infill - even at 100% fill I'm pretty sure the continuous bead of the shell will be stronger than a fill matrix.

    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.

    1, 2 and 3. Yes.
    4) It depends on which bike and what I'm doing / where I'm going. Arriving with things wet or dirty is a frequent source of annoyance this time of year. (Things being typically tools, spare clothing, wallet, keys, phone, Ventolin)
    5) Attachment to bike (related to security and stability)
    6) Light mount, definitely. Reflective elements possibly.
    7) Medium? Around 5 litres mostly works for me.
    8) Grey or black. Just measured my favourite saddle bag - rectangular(ish) box at 20x20x12cm.
    9) An internal loop for securing items such as keys for house, car & bike lock. Internal pocket with an additional closure would work equally well and also hold a wallet & phone.
    10) Permanently attached is only ok if there are no high value contents - detachable with a carry handle / strap (or maybe a removable inner compartment) often makes more sense.

    You might think how to present the answers to 1, 2, 3, 7, 8, 10 as percentages or in graphical form to justify your conclusions: qualitative answers (4, 5, 6, 9) can be difficult to analyse when there are enough of them to make a survey worthwhile. Don't spend too long on research because making and testing a prototype will take more time than you can imagine! Good luck with this.

    Read 'The Age of Surveillance Capitalism' and try not to worry that it's already too late?

    A friend mentioned ukuleles in a recent group e-mail, and for a time my Pinterest feed was full of pretty pictures of the bloody things. Apparently one of us has a Gmail account...

    I saw rough sawn seasoned cherry planks in the NT shop at Attingham yesterday - not London but Google suggests Hatfield Forest might be a possibility?

    Just out of curiosity, are you laser cutting holes for the thread? I used to do a bit with a GCSE Textiles group, and laser cut holes at uniform spacing made for quick and accurate leatherwork that a pupil could do by hand with an ordinary needle (and Corel Draw and a CNC laser)
