The file 'Brompton Light Bar 3D Printer Model' is (STL) file type, size is 479.9KB.
I've been using this on my 2020 Brompton M6L-E to mount some lights and I've been really happy with it for four years and have not had any issues. I don't know what other bars it will fit but a few people have report the fit not being perfect on their bike. One person has suggested simply scaling down 1-2%.
Fitting to the bars just requires four cable ties
