OpenDryer [Filament Dryer]

Boost Me🔩For more electronics stuff⚡

First question: WHY. Why not just buy a PolyDryer?

My answer: full control.

 

The PolyDryer isn't a bad machine, but the fact that it only has three settings instead of letting you adjust the temperature is just ridiculous. And the price isn't something everyone can easily afford either.

 

Here are a few reasons why Opendryer:

• Compatible with most PolyDryer mods (in terms of the top connections)
• Set your own temperature, whether it's 75, 66.5, or 55.3 or more.
• As the name OpenDryer suggests, it’s OPEN for improvement, customization, and creation. A Step file is provided. And I ask that any remixes be linked to the project.

• Price: Opendryer costs between $20-30+-.
