Filament dryer extension for Brentwood + similar dehydrators

prusaprinters

Convert a food dehydrator into a filament dryer without breaking any racks! This extension gives you ample room for a 1kg roll of filament and the divots in the dehydrator lid. It prints in four pieces (compatible with the Prusa Mini) that slot together.It turns out most food dehydrators are the same models using different brands. This dryer extension should work for the Brentwood (mine), the Westinghouse, the Commerical Chef…and perhaps yours? It's ~23 cm in diameter.Remixed from walter's Filament Dehydrator Tray Extensions specifically for the Westinghouse, using Haprog's slot mechanism for an unrelated model. There's a lot that could be improved upon, but I got tired of burning through so much filament! In particular, other racks/the lid do not fit securely on top of the extension due to the sliders, so it's not particularly sturdy. It was also a terribly tight fit (I cracked a piece trying to slot it in). You could also make it smaller; even accounting for the lid divots, it's still taller than necessary. (Or larger; it needs maybe 1-2cm to fit a second roll.Vase mode was unsuccessful for me, seemingly due to the overhang. Print in PETG or similar heat-resistant material, especially if you have the one-setting Brentwood. Doesn't need supports. Don't print with a brim if you can avoid it, and definitely don't accidentally turn on fuzzy skin like me. Also, don't buy the Brentwood.
