8mm rod holder for Kigima filament box

thingiverse

I finally found a box in Germany that holds a single filament spool and is not overly expensive. You can find it on Amazon as Kigima Müsli box with 5,7l volume. 3 of these cost 18 Euros. For my setup this is easier than a big box with multiple rolls, but this depends on your usage case of course. To make things easy, I drew this rod holder to hold a 8mm rod on which you can put your favourite spool hub. I use [this one](https://www.thingiverse.com/thing:3118978) and the outlet for the PTFE tube is [this one](https://www.thingiverse.com/download:5881906). If you like you could also add a hygrometer. I found [these ones](https://de.aliexpress.com/item/Mini-Digital-LCD-Indoor-Bequem-Temperatur-Sensor-Feuchtigkeit-Meter-Thermometer-Hygrometer-Gauge/32936762466.html?fbclid=IwAR2cpzsE0I0pdSfXLRnK2sdcqv4fahF9j3u2vfcUnkqIRbzWPn2qhVjyI_c) to easily mount. The rod holder has a central hole where the rod will sit later - this is to make marking the holes to drill easier. You first mark the desired position with a pen on both sides (by measuring first of course ;-) ) and then you place the printed holder on the outside and align the center hole with your marking and then you can finally mark the 3 holes to drill so that you can add some M4 screws and nuts to fix the holder to the box. Add some silica and you have a nice box that keeps your filament clean and dry.
