10M Test V2 - 10 Minute Mini Calibration Print

thingiverse

What is it?The 10M Test can be printed in 10 minutes This is a very compact test and calibration model for 3d printing and supposed to supersede my previous model https://www.thingiverse.com/thing:1815784, while keeping the core idea of a 10-minute test. It's goal is to make a test print for various design elements.What is the reason in it?Main goal was to make a calibration test as tiny and effective as possible for regular 0.2mm resolution printsSave as much material as possibleSave as much printing time as possibleShow useful test results for retraction and printing qualityOnly include the most important and basic tests for proper calibration (in my opinion)Why this and not others?There are plenty of other test models out there, either with a very big range of tests, or just one test. Usually they are using a lot of printing material and printing time. However I just wanted to make a quick check, if printing results are okay. Compared to my V1 design, which was really useful over the years, I felt that within 10 minutes more could be tested.What is in it?Fast: Print in less than 10 minutes (depends of course on printer speed)Small and lightweight: 1.3g at 40x13x12mm3D printer friendly: No supports, rafts, brims, ...Bridging at ~ 16mm: Top bridge with 1 layer only (0.2mm) and bottom bridge with 3 layers (0.6mm)Stringing and oozing check between left and right towerOverhangs at 40°, 50°, 60°, 70°, topped with a 9 x 9 mm square surfaceSlots/gaps at 0.1mm, 0.2mm, 0.4mm, 0.6mm, 0.8mm, 1.0mmFillet 2mm and 6mm in layer directionChamfer 45° in layer directionLetters with 4mm heightTapered tip 45°Inner edge 90°Use overhang structure as a handle to easily remove from a sticky printing bedSpace for label sticker on bottom side (12x24mm)TipsTop and bottom layers: Make sure to have enough layers, so that there is no infill below the text and gaps/slots!Layer height: Can be also printed with other layer heights than the "default" 0.2mm, but check layer amount setting, tip #1. Also note, that the top bridge has a height of 0.2mm, which may have then more than 1 layer (e.g. at 0.1mm layer height) or disappear entirely with higher layer heights - though all depends on the slicer settings.Overhang: The upper overhangs at 60°, 70° are of course challenging, don't be too sad if that won't work out well. IMO good designs for 3d printables should anyway never have overhangs >45°. If the top square is off, then the 70° might be too much of an overhang to handle.Z Seam: Recommended to put it manually on the long continuous, 6mm fillet side without the steps (backside I believe)
