This is a remix of thing:566321. The original was difficult to print in PLA and did not fit well. I reduced and added some material and created an STL file to print it vertically. The one pictured was printed with 15% infill density, 0.3mm layer height, and with support. I use a simple pick tool to remove the support material which can be seen in the picture.1.75 PLA 15% infill density 0.3mm layer height With support
