Gravitrax organizer tower === ### Main features * Accomodates up to 6 x 13 = 78 standard Gravitrax tiles * Compatible with most white parts with rail connectors * Printable on any FDM printer with 20x20cm baseplate * Assembly requires no glue * No supports needed Printing instructions === ### Inventory * 1x Bottom * 1x Top * 1x Handle * 3x Retainer * 6x PillarL * 6x PillarR Instead of arranging 6x PillarL and 6x PillarR on your printing bed, you can alternatively use the Pillars12.stl file which contains all required pillars arranged in a dense pattern. ### Printing advices Be advised: **This is not an easy print !!!** * Make sure your printer is well-levelled across the whole printing bed. The pillars are long and contain fine details. When the first layer sits too tight, you will get an *elephant's foot* and the clips will be too tight. Otherwise, when the bed distance is too high, the parts will self-detach and/or warp upwards. * This has been tested with PLA only, print with other materials at your own risk. If you try, please share your results. * The pillars have quite thin lines and your slicer might decide to add some gap filling here and there. Because of the size of the pillars, this might add a lot of retractions which might grind your filamend and lead to underextrusion or completely failed prints. If that happens to you, disable filling gaps and thin lines, and play with extrusion widths and check the paths computed by your slicer. * Before printing all 12 pillars in one go, I advise you to make a test print of one pillar first. * Make sure that you print hot enough and/or reduce layer height if you have the impression that things break along the layers. Printing hot is especially important when you use material that is well-known for not having good layer adhesion (e.g. extrudr NX-2) However, the most important advice is: * **PRINT SLOWLY**. Don't rush! You don't want to have any printing artifacts on the pillars. I printed overnight at 20-30mm/s max. Assembly instructions === See assembly video here: https://www.youtube.com/watch?v=TI-7mkkhKHQ Start with the bottom part. Now, sort the pillars into pairs of left and right ones. Look for the small arrow on one end of each pillar. The arrow should be at the very bottom and point upwards. The left and right pillars should be inserted into the stand so that their domes touch, assuring the right distance across the whole height of the structure. Depending on how accurate your print was, you might need to use some force until it snaps in. When all 12 pillars are standing, it's time for the retainers. They ensure that the pillars stay in place and give the whole structure its stability. Insert the retainers from above. They have clips that should snap onto the domes of the pillars. Start with the bottom-most retainer, then the middle and then the top-most. Now snap the U-shaped handle into the top part. Depending on how much infill you used, you need to use some force to squeeze it before it goes in. Make sure that the connection is tight after snapping in the handle. If you are not confident, you might apply some glue. But it should not be necessary if your prints are clean. Now you can snap the whole top part onto the remaining structure. Align the grooves with the top ends of the pillars and push the whole top-part downwards. It should snap-in and not be easily un-snapped. Again, If you are unsure and are afraid of the top part coming loose while carrying all your precious Gravitrax extensions, you can apply some glue. It should not be necessary, though.
