Description

TOP and BOTTOM Lego to Gravitrax adapters to use as Gravitrax spacers to build towers. With Lego you are free to adjust height as you want, and build as high as you want without wasting a lot of Gravitrax spacers. 📷 Image redacted — claim this model to add your own media If your printer is calibrated, all dimensions should fit between Lego, Gravitrax and adapters. Also, if you calibrated bridges, these parts can be printed without supports. Please check that kind of calibration using Orca Slicer 2.3.2: https://www.printables.com/model/1482067-bridge-density-experiments Suggestions for print: - 0,2 mm layer height - min. 3 walls - min 1 mm or 5 top and bottom layers - I use 5% honeycomb infill for evenly spread and support top layers - with these settings BOTTOM hex ring should be printed solid Bridges without supports for my Qidi Q1 Pro printer: - be aware that these settings are individual for every printer! - speed 10 mm/s, bridge flow ratio 1,3 and bridge density 120% Hex Ring for BOTTOM adapter should fit snugly, push it in place with force, no need to use glue. If printed parts are to tight for you: I suggest changing X-Y compensation parameters in your slicer. To demonstrate how that works, see picture below. 📷 Image redacted — claim this model to add your own media
