Donation Box - "Conversion Kit" for Suction Strainer Pen Holder

Due to many requests, I have now also designed an insert for use as a money box or donation box, specifically for the suction strainer pen holder.

The money box insert is inserted into the coupling instead of the "seal" and glued. The insert has a thread to screw in the corresponding counterpart with a coin slot. As a small aid, I have also created a kind of "key" this time, which makes screwing in and out easier.

For all those who want to use the suction strainer as a donation box, I have additionally created a corresponding "DONATE" sign which can be printed. This must be glued with adhesive (preferably superglue) onto the existing grid basket of the suction strainer.
