Summary

When searching for double-walled funnels as tool for separating my IPA from the resin inside I only found relatively small funnels. So I created my own, fitting the usual size 6 coffee filters.
The funnel is divided in three parts: the internal filter holder, the external holder and the bottom nozzle to be screwed into the external holder.
