This Model was created to hold coffee filters for drip methods. After few invalid iterations and failed hold system, finally I created this to work with Ikea Skadis or as standalone.

Personally, I am using with small skadis table with other coffee accessories.

It works with all flat filters (Chemex, V60, Moccamaster, Melitta etc). 

You can also use magnets, but 6x3mm (hole size) are too weak for this model alone :)

Have fun and send realizations.
