Quick clearance test.

Based on a great idea of J Jake 3D https://www.prusaprinters.org/prints/127569-s-shaped-tolerance-test-01-04mm-in-002mm-increment I upped the challenge such taht the test also includes layer and line changes and thus zits will show up as fused points.Start with printing J Jake 3D's test as its way quicker to print, when your tuning is such that 0.1 mm is achievable this is the next level challenge.print settings:0.2 mm layer height0.4 mm outer layer width0.45 mm inner layer widthother settings as per your typical print settings.My learnings how to improve clearance:Properly tune Pressure/Linear Advance. This is probably the setting reducing the zits the most.Your filament flow has to be tuned properly, any over-extrusion will close the gaps. I set outer layers to under-extrude 5% and inner layers to over-extrude 2% to achieve the best accuracy, esthetics and strength compromise.Retraction may be set ~20% higher than the minimum outcome of retraction tests (http://retractioncalibration.com is my favorite retraction test).Next challenge: https://www.prusaprinters.org/prints/129499-clearance-test-a-new-challenge-who-unlocks-the-006
