Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4818867.
just to be clear: i designed this from scratch, but i marked it as a remix, as the design from Tom--DK was my inspiration.
i really liked the design that holds beer cans by Tom--DK. https://www.thingiverse.com/thing:4760105
i just don't drink beer out of cans, and it was too large to be printed on my ender 3 pro. so i designed it to fit 0,5L bottles, divided it to 8 parts, and added the handle and lids separately.
the lids are a little loose, so they might come off too easily. i recommend glueing them on, or making a remix. i might upload a better version of them
things to print: 2x Side 2x Side mirrored 2x Middle 2x Middle mirrored 2x Lid 2x Lid mirrored 1x Handle i'd recomment printig with at least 3 walls and 20% (cubic) infill. it should take a total of 1,2 - 1,5 kg of PLA to print.
additional materials: 34 screws M4x16 52 nuts M4 - or 34 nuts M4 (see below) 68 washers M4
since i had minor warping on the 8 sections i decided so "conceal" that by adding M4 nuts as spacers. but don't add these "spacer-nuts" along the middle (long-side; below the handle), otherwise the 2 sides of the handle (with the screw holes) will be too short. if you don't use these "spacer-nuts", you have to scale the length of the handle down by 2%, otherwise it will be loo long.
printing oriantation: i printed the 8 sections on their sides, and used custom supports only for the (now horizontal) 3 screw holes of the middle sections. if you're having trouble with overhangs you might want to use automatic generated supports the handle was printed upside down, so the top side would look ok, with the trade off that the sides with screws on them don't look as good, because they need supports.
update 21.08.2021: added mirrored versions of "side", "middle" and "lid" as requested by user amipower
update 22.08.2021: uploaded a reinforced version of the lid (named Lid 1.1 +mirrored file); so now it should stay in position more reliably
