Modular castle kit - Duplo compatible

<p>[Imported from thingiverse and outdated. I am working on a new version, available soon. DKS, Jan 2022]</p><p>Blocks" that can be horizontally assembled into a large medieval castle,<strong>DUPLO size</strong></p><p>Your choice:</p><ul><li>Print bricks with base platform attached</li><li>Print stackable objects that you can put on top of a base plate</li></ul><p>Combine the two The source code is no different from its "parent", i.e. thing <a href="https://www.thingiverse.com/thing:31284">http://www.thingiverse.com/thing:31284</a> that uses<strong>LEGO</strong> size for the STLs.</p><p>I just generated DUPLO size and proportions instead of Lego size and proportions, for folks who don't want to learn OpenScad.</p><p>Therefore this "derivative" is just a Duplo "subdirectory" that includes a subset. Please go and read the rest in the parent.</p><h3>Instructions</h3><p><strong>Disclaimer</strong></p><p>I didn't print any of these models. However, I did print similar structures. See a picture in <a href="https://www.thingiverse.com/thing:2106">http://www.thingiverse.com/thing:2106</a></p><p><strong>Expected problems</strong></p><ul><li>floors over DUPLO-base (nibbles underneath). Plastic may bond sideways and in knots: Try to print as cold as possible (and tighten the extruder). In addition - as soon as you get irregular surfaces in large horizontal fully filled roof layers - you could turn off the fan, so that the nozzle won't get stuck.</li><li>The visible top layer of a base plate should come out ok if you use enough fill and the bottom will be ok iff you print it slowly and nozzle real close to print bed.</li><li>Random filament feeding problem after many hours of printing.</li></ul><p>Ugly horizontal overhangs, in particular with nice modern low-resolution printers ;) <strong>Suggestions</strong></p><p>I suggest to print these models as speedy as possible, unless your printer doesn't mind 24hour prints.</p><p>However, the first layer must printed very very slowly.</p><ul><li>You could try fairly thick layers (e.g. 3.5mm). I did print a fairly nice looking castle over 2 years ago with a RapMan... Try with the small calibration block first.</li></ul><p><strong>Fit</strong></p><p>Fit of DUPLO-compatible connectors is rather loose in order to compensate for sloppy quality and thicker layers.</p><p>If your printer is reliable and you don't mind waiting a day, try 0.2 or 0.25 layers with a rather dense fill for good results. In any case, for quality, you should not use these STLs, but rather adjust the parameters in the OpenScad file (see the "parent", <a href="https://www.thingiverse.com/thing:31284">http://www.thingiverse.com/thing:31284</a> as well as my OpenScad library: <a href="https://www.thingiverse.com/thing:2106">http://www.thingiverse.com/thing:2106</a> which does the work behind. These Duplo models are just lists of function calls...</p><p>Category: Construction Toys</p>
