Small add-on for the Filament Spool Holder from ThomaS - suitable for the IKEA Samla 22l boxes.

For additional control of the humidity and temperature in the filament boxes, I have designed a small holder for the common mini LCD thermometer hygrometer.

The holder is fixed by slightly lifting the spool holder frame and sits directly on the frame. As I store the boxes in Kalax shelves, they sit lengthways in the shelves - hence their placement in the front right-hand corner.

I have tested the holder with these two mini thermometers from the big A and they snap perfectly into the printed housing. The back is intentionally open for measurement and battery replacement.

Here are the links to the two sensors tested:

Don't be alarmed by the values displayed on the mini hygrometers in the photos - I had them in my hands to take the photos ;-)

Perhaps someone else could make good use of this holder...
