Bed level test - human transmutation circle

thingiverse

It's a bed leveling test resembling the transmutation circle from Fullmetal Alchemist, encompassed by a substantial square. Drawing this design was simply a fun challenge for my printer. The test measures 200mm x 200mm, which is comparable to a standard Prusa table size (my own Mk 3 table is slightly larger at 220x220 mm). However, you should adjust the size in your slicer to accommodate any additional surfaces, such as glass or wood panels, that are secured with clamps. This adjustment will prevent the head from colliding with them or drawing outside the designated area. Printing this design takes approximately 20 minutes when printed at 95% scale and a speed of 30mm/s using old Cura software on an Anet A6 printer. The presence of various symbols, circles, and both thick and thin lines makes it an effective tool for determining whether your bed is levelled correctly and if the printer accurately draws circles and identifies its starting point at the table's edge, which becomes crucial when printing large items or multiple objects simultaneously. I've added a revised version with increased material on the corners.
