Thermos knockoffs in Europe

8 replies6 peopleMay 1, 2026☆ Follow
Summary

Where can I find a food thermos with matching 3D printable inserts for storing lyophilized peptides, preferably in Europe or as a budget alternative?

Users discuss locating suitable thermoses that allow use of existing 3D insert models for snug vial storage. Several report finding workable alternatives from various retailers with available print files, though one notes thread quality issues on certain units. Others plan to test cheaper options for stacking vials with added filler materials like silica gel. The thread focuses on practical fit and local availability rather than perfect insulation.

Just picked up some freeze-dried peptides recently and now need a solid way to keep them stable for a long stretch. Clips online pointed to one specific insulated bottle as a good option. Plenty of printable insert designs exist that match its size exactly, so tracking down that bottle would work best. Any users based in Europe aware of places carrying it or a close copy with identical sizing? I suppose I could always build my own inserts to fit a different insulated bottle instead, though that feels like extra effort for no reason.

I've spotted comparable items from elsewhere with altered measurements and the printable design file for that edition is locatable.

Meanwhile i've found a very good alternative from a furniture retailer. One model looks promising so I'll be visiting tomorrow. Also some good 3d print files available.

I recently purchased a one-liter insulated container. It probably won't excel at holding temperatures, yet if the measurements line up well enough I should manage to place two sets one over the other while leaving extra room along the sides for loose tubes. A layer of cushioning material might help guard against bumps. This works as a low-cost version of that setup.

Update me on how things turn out. Being detail oriented means I like my container held securely without any room to shift around. That's just how I am.

Once things are prepared I'll share some images. I also have a hundred desiccant pouches on hand. They'll occupy any empty spots. That container will end up extremely arid inside.

Picked up a few of these, not for any peptide stuff by the way. The worst part for me is the messed up threading around the openings. I regret not looking them over at the store before grabbing three. One came out fine but the other pair makes screwing the top on tricky since the lines don't match up. Just saying in case it affects others too.

I have two from an online marketplace and the printed inserts fit perfect! Happy with them!
