Magnet Stirrer Helper

I use a magnet stirrer for cleaning my Resin prints, but somehow the IPA couldn't quite flow. So I created a little helper.
Place the lower part into the glass, put the printed parts on the upper part and place the upper part on the lower part in the glass. Switch the magnet stirrer on and clean your parts.

I designed the helper in two parts. a lower part that stays in the glass and makes the IPA circulate and a upper part to put the prints on. There are two vrsions of the upper part. One with 10mm spikes and another with 20mm spikes.
