![]() ![]() This took almost 3 weeks and the result is more than 1 GB in size. Thanks! Another user managed to generate an order 7 model. IRC channel (and especially InPhase) have managed to generate an order 6 model, which I included as an STL file. However, processing time and resource requirements will raise increasingly faster with higher orders. Generating order 6 and even order 7 models should be possible with the latest OpenSCAD builds. On my computer it took about 90 minutes to generate the order 5 file included with this Thing. If you want to generate an order 5 pyramid, you will need to download the SCAD file and run it through OpenSCAD yourself. If Customizer is broken on the Thingiverse website, here are instructions () to run it on your own computer.Ĭustomizer is limited to an order 4 pyramid because higher orders take so much time that the Thingiverse server would most likely timeout, leaving you with no model. You can make your own custom pyramid in Customizer. The same goes for the order parameter: if a model of order 2 prints alright, then an order 3 or 4 model with the same parameters will print in exactly the same way. This ensures a consistent print from top to bottom, it also means you only need to check whether the bottom level of a model will print correctly, because the higher levels will be printed in exactly the same way. Of course I also had to litter the code with fudge factors and some geometric tweaks to avoid non-manifoldness problems, which Slic3r is particularly sensitive to.Īnother change is that the model will auto-align itself to the print layer height (default: 0.2 mm). This produces a cleaner model and avoids inaccuracies or slicing errors when cutting right at the division between two pyramids. Instead of stacking small pyramids together like aeropic's code, holes are cut out of one big solid pyramid. I started out fixing these issues, but in the end I rewrote a large part of the code to construct the model in a subtractive way. The parts connecting the pyramids are too small, which causes them to become separate perimeters as well. It should be set to slightly less than half the gap size that can be set in Customizer.Ģ. It is the ‘Slice gap closing radius’ in Print Settings → Advanced. Note: the most recent Slic3r PE releases do allow to override this gap size. ![]() It uses gaps of 0.01mm, while Slic3r fills gaps smaller than 0.1 mm (see issue 520 in the Prusa3D Slic3r GitHub). However, neither does aeropic's model, for two reasons:ġ. One of the problems with ricktu's original model is that it does not work with Slic3r's spiral mode. This produces a model of high quality in a surprisingly short time (and causes your printer to make funky sounds). As described in ricktu's () and aeropic's () original Things this one is based on, the 3D model can ideally be printed in ‘spiral vase’ or ‘spiralize outer contour’ modes of slicing programs, which means the whole print can be done in one single continuous line with no retractions. The difference with the straightforward pyramid is the addition of inverted pyramids to make this 3D printable. ![]() This is a variation on the square Sierpinksi pyramid. ![]()
