I created this simple model, which is used as a spacer when placing hexagonal wall art on the wall.

The artwork that needs to be referenced is this -https://makerworld.com/en/models/138220#profileId-150513

The width of the spacer blocks is 8 mm, which is the same as the width of the hexagonal wall.

Print two copies and simply put them on the wall.

The configuration file is for a 0.6-millimeter nozzle, because I'm using wood to print decorations.

The integrated 3D files are already included, in case you need to modify them according to your own requirements.

There are 90-degree/square/cross versions here -https://makerworld.com/en/models/163189#profileId-179164
