Dryer Rack for Freezer/Storage Bags

Concerned about the impact of plastic on our environment? Re-use your freezer and storage bags!

We like to wash our freezer bags and re-use them. Wife used to have a drying rack like the one here that she bought a long time ago in a galaxy far, far away... Well, the drying rack broke so I was tasked to design a replacement one. Here's the result. It can hold up to 3 bags.

Version 2.1: My wife finally managed to break one of the stems, or rather the thread from the base… I used to opportunity to improve the model by adding a wide chamfer to the stem, to counteract lateral stress. As a result, each “flower” now needs one “stem” and (at least) one “extender”. Base needed to be increased a bit in diameter. 

Print instructions

One unit consists of 1 base, 3 flowers, and 3 stems. I would suggest adding one extender to each stem, for use with gallon-sized bags. Just the stem should be okay for quart-sized bags.

I printed everything with 0.2 mm layer height, 15% cubic infill, no supports, using PETG but I don't think PLA would be a problem. It's not that these bags are dripping wet. I used 3 perimeters for stem and extender.

The stem/extender components come with built-in sacrificial supports, to stabilize them. They should easily break away.

When you screw things together, remember these are 3D printed parts, not metal, so use mild force to avoid shearing the male parts of the threads off.

3MF files with suggested settings are included.

Version History

Version 2.0 (August 10, 2020): Replaced the previous press-fit with threaded connectors for base, stems, and flower. Replaced the previous flower (tulip) with a rose. Now prints without supports.

• The flower is a remix of XYZWorkshop's anniversary rose (https://www.thingiverse.com/thing:152642)
• The idea for sacrificial supports for the stems comes from FFFTechnology's e-vise 2 (https://www.prusaprinters.org/prints/52457-e-vise-v2)
