Simple Replicator 2X Spool Holder / Rollenhalter

based on JimFouch's "Simple Replicator 2X Spool Holder Replacement" i designed this one for German standard PVC "Elektro-Installationsrohr" with a 20mm diameter.

I added a radius to the connection fillet between the plates due to durability. My first made with the original design broke with almost no stress.

Be careful attaching the tube, because i made it a very tight fit ;-)
