I wanted to make a fun and creative pen holder, and this is what I came up with. A pen holder shaped like an archery target.
It works by pressing t...he pens through the holes in the base, and because it's only one layer thick (.2mm), it flexes and holds tightly around the pens.
You assemble it as shown in the gif on the bottom of this page. You do need a small strew and nut to mount the base onto the stand. But you basically screw the base and stand together, then fit together the rings on the base, and set the leg in place, by punching the pin into the hole in the stand.
PLEASE NOTE: YOU DO NEED TO STICK IT TO THE TABLE SOMEHOW, TO KEEP IT FROM FALLING OVER.
This is just my attempt on this 'technique', so fell free to improve on my design. But I hope you like it.
