Lincoln Log inspired Log Cabin stackers

prusaprinters

These notched blocks can be stacked up across each other to build complex rectangular structures. Great fun for kids. All of the blocks are rectangular in section with 45° chamfers so they can print in FDM without support. The standard shape ones  should be printed sideways. The half blocks should be printed with the flat side down. The 3-notch block can be printed on a Ender3 sized printer easily along the X or Y axis. The 4 notch block can only be printed at a 45° angle. I printed mine with .2 layer height (.4 nozzle), 1.0mm walls and 15% gyroid infill.
