Core One PolyDryer Shelf

Want to use a PolyDryer filament drying dock with your Prusa Core One printer? Neodymium magnets anchor each of these brackets to the frame of the Prusa Core One. The brackets provide secure and level support for PolyDryer filament storage, ensuring that the filament remains dry and minimizing its footprint. Each bracket grabs one foot of the PolyDryer, locking it in place.

My original upload uses a pair of 10mmx5mm neodymium magnets on each bracket. A nice commenter asked if I could make a version that used three or four 6mmx3mm magnets, which are more common. Sure, I said. I deleted the original holes, ran a test print to figure out the right size for a snug 6mm magnet, added four new holes and printed the result, then thwacked in the smaller magnets. They're too wimpy. The bracket mounted successfully and supported its half of the PolyDryer, but it was weak support that would collapse if it was nudged by a cat or a kid or a clumsy printmeister. A magnet-selling website says this size magnet has about two pounds of pulling force, but I don't think mine do and I won't pursue this variation.

(If you want to experiment with alternative magnet arrangements, I've included a no-magnet STEP version of the shelf along with cutters for 6x3mm and 10x5mm magnets. They're in the file labeled PolyDryer Core One Adapter Uncut.)

You can buy twenty 10mmx5mm neodymium magnets online for less than $10. But be sure they're actually neodymium: you need the strength.

Remove the standard spool holder to make room. The magnets are friction fit: just tap them into place. (As the weather turned warmer the magnets loosened, so I fixed them in place with a few drops of glue.)

Printed on Core One in ABS with organic supports. Should work equally well in PETG or PLA.
