Polymaker H/PolyDryer™ Box/

Very well-built and thoughtfully designed. The box seals tightly, feels sturdy, and keeps filament reliably dry. The spool runs smoothly, and the viewing window is a nice touch to quickly check how much is left. I especially like that you can feed the filament directly from the box — no rewinding or mess. It also looks great and fits nicely into a printer setup. One star off because the price is a bit on the high side. Otherwise, it’s an easy recommendation for anyone who values clean, dry filament storage.

Outstanding product. Packaged very well and secure for shipping. Printing mostly PETG, they keep my filament in a perfectly workable state after dehydrating. The digital hygrometer is very responsive and accurate enough for the use case give or take 1-5%. They are nice and compact fitting nicely on shelving for storage. I am a little worried about the clamping sides as they are slightly tough to snap on and engage. Putting the lid on slightly wrong may result in breaking those clamps. I would keep an eye on this. The filament holes on the top and front are great for their use case. I look forward to purchasing more of these as my color library continues to grow. Highly recommended 5 Stars.

Très bon produit pour conserver le filament parfaitement étanche, cependant si comme moi vous l’utilisez comme boîte de conservation ou pour imprimer, prévoir quand même un sécheur de filament pour d’abord bien enlever l’humidité de ce dernier pour une meilleure conservation dans la boîte.

e' il 5 che compro molto contento del prodotto, consigliatissimo a chi come me vive in zone marine con molta umidita

Erg praktisch. Ook om kleinere spoelen, die niet op een spoelhouder van bijvoorbeeld de Centauri Carbon passen, direct vanuit de box te laten printen. En je filament is dan ook afgesloten tijdens het printen. Je kan zelfs drogen en printen tegelijk, mocht dat nodig zijn. Voor opslag is het vooral interessant voor veelgebruikte spoelen/kleuren gezien de prijs. Enige minpunt: display van de hygrometer is niet altijd even makkelijk afleesbaar.
