Compact Printable Spool Holder for Cereal Tupperware Container Single Filament Dry Box

thingiverse

I needed a dry-box for my filament and wanted something that I could print from, as well as being relatively small because I don't have much space. I was looking for something that was big enough for a single spool. I found Cereal Tupperware and used this one https://www.amazon.co.uk/Addis-Close-Cereal-Container-Litre/dp/B003VYAK0C/ these things are much more expensive in the UK than people in the USA seem to find them for. None of the spool holders I found would fit, this container is only just big enough for the spool; so I created this design. I attach the design files so you can change things up. My design skills are pretty bad so it might be a mess. If you need a different file format let me know, --- Print list: - 1x main_body.stl - 1x bar.stl - 4x leg.stl The bar is designed to fit this container, the container is what stops the bar sliding sideways enough to fall off. You need to glue the legs into place, and I cut the legs in half otherwise it was too tall in the end. The legs are to leave more space for desicant underneath. There is a bit of friction between the spool and the container but this has not caused me any problems when in use. I ended up using a file to file away some of the inside of the container - you can just about see this in the picture where the purple sharpie mark is. I drilled a small hole in the front of the container, and glued in a 1 inch length of PTFE bowden tube that I had left over, I feed the filament through this hole. I cut a hole in the lid big enough for a cheap humidty sensor that I got off Am4zon and glued it in there. This maintains ~17% RH with the dessicant in there although I suspect the RH is actually lower and that the sensor cannot read it that low - I average ~70% RH in my flat... [Kettlefish1](https://www.thingiverse.com/kettlefish1/designs) has created [a remix of the main body](https://www.thingiverse.com/thing:5148944) so that it can house the temperature/humidy sensor without needing to make another hole in the cereal container. --- Maximum spool sizes: 69mm wide 120mm from where the spool would rest on the bar to the lowest point (although I'm not sure this will fit in the container) This was designed to fit a SUNLU master spool
