Attachment ring for FM Matttsson soap shelf

Spare part for the soap shelf S600331 in the FM Mattsson Siljan series. Sold in Sweden as "Distansring" or "Fästring" with number S600336 There are three variants for different pipe dimensions. Note that I have only tested the 20mm version, so send a message if the others need some adjustment. I have printed with standard PLA with 20% infill. Any material which is not too rigid should work fine.
