      Text, star & nut size
      The star and nut look pretty decent but the surface finish is terrible.
      The nut hole is really rounded.
      Text has a thin bottom layer.
      Everything looks really good.
      Spike, pyramid and concave
      Just a square hole where the pyramid should be, nothing else printed.
      Rounded concave print looks a bit rough. The spike was longer before we separated the print from build platform. I think it was almost as tall as sindoh's. Toni said that the spike was tall but had alignment problems.
      Concave and pyramid features are smoother than in fortus's print. Top of the spike has long and pretty thick string all the way to the warp test.
      Everything looks good. Spike is really sharp.
      Overhang 25°-70° in 5° increments
      Nothing printed.
      The 65 and 70 degree test have thicker bottom side.
      Top corner of the pillar is messed up in every test.
      Looked good
      Warp
      Nothing printed.
      Looks good.
      Has a bit of surface roughness on both sides from stringing.
      Looks good.
      Hole in the wall and Z-height 0.1-1.1 mm in 0.1 mm increments
      Apart from the surface finish the Z-height looks suprisingly good. Wall didn't print.
      5 of the 11 Z-heights visible. Overhang of the whole was too much.
      5, maybe 6, of the 11 Z-heights visible. Helo in the wall is pretty clear.
      Can't tell from the picture because of the IPA smoothing the surface and I don't have the part at hand but I think all Z-heights were printed. Hole in the wall looks smooth.
      Bridge 2, 4, 8, 16 mm apart and 3D optimized font
      Markings looks better than sindoh or fortus. Nothing else printed.
      Bridges are narrow and have lot of stringing. 16 mm bridge is drooping. 8 and 16 markings are unreadable, 8 looks like 6 and 6 looks wonky.
      8 mm bridge has small drooping. One of the pillars has couple of really thick strings stuck to it. 16 is unreadable.
      16 mm bridge is drooping. Markings look good.
      Wall thickness 0.7-0.1 mm in 0.1 mm increments and wave
      Wave looks pretty good. Walls not printed.
      Only 0.7-0.5 mm walls printed. Wave looks good.
      0.7-0.5 mm walls printed but they have lot of layer mismatching. Wave also has a tiny amount of mismatch.
      All the walls printed. Wave looks good.
      Minimum distance 0.7-0.1 mm in 0.1 mm increments, holes, spehere and text
      Minumun distance is really good. 0.3mm gap is clearly separated and 0.2 allows a light come through.
      0.5 mm gap is the smallest one. Sphere and holes are pretty good.
      0.5 mm gap is the true smallest gap but elephants footing ruined the smaller gaps, maybe fiaxable with raft? Holes are rougher than in fortus' print. Spehere has piece of filement stuck on top of it.
