Kitchen rail system based off of 20 mm conduit.
Print two or three wall mounts and two end caps. Cut the conduit to appropriate length.
Mount the wall mounts with screws or double sided tape. Insert tubing and put the end caps in the tubing.
Should your chosen pipe or rod not fit the wall mount, I've included .step-files so you can change them to your hearts content.
Add your favourite tools to it with the Kitchen Appliance Hooks and Paper Towel Holder.
