About this 3D model

I needed a long shelf for my honeycomb storage wall, and couldn't find one so I created one that was as long as I could possible fit onto my X1C build plate. It measures 301.69mm x 150mmx 40mm (LxWxH). If there's any interest in different lengths lmk and I can add those, otherwise I've included the STEP file so that you can make your own adjustments. This is designed to be used with the M3 insert because i find that accessories with multiple hexagonal pegs are often incredibly difficult to remove, this way it can easily be unscrewed and the individual insert are easy to remove by srewing it an M3 screw part way and yanking it out with a pair of pliers. I printed it out of PLA and it turned out great, with the following print settings: 4 wall loops 4 top shell 4 bottom shell 15% gyroid infill 15mm outter brim 0.16mm outter brim gap
