M3 Spanner

M3 spanner. I used sketchup to create this and you can download the file if you want to scale it up to other sizes (thus I didn't write the size into the part). I use it for getting under the heatbed to tighten one or two bolts. My printer has a magnetic heatbed so having a plastic spanner made it easier without scratching the underside. It was printed on my Prusa MK3 and took about 11 minutes at .2 layer height. It is 90mm long and 3.5mm high, simple but strong. It fits the bolts perfectly.
