{"product_id":"flexi-rex-with-stronger-links","title":"Flexi Rex with stronger links","description":"\u003cp\u003eThis is my improved version of the classic Flexi Rex. Somehow this version became the most popular one, maybe just because it doesn't break easily when handled by kids (and adults of course).\u003cbr\u003eThis model has existed since December 2017, but I uploaded it to MakerWorld as well for everyone's convenience. \u003cstrong\u003eThe primary source for this model remains \u003c\/strong\u003e\u003ca target=\"_blank\" href=\"https:\/\/github.com\/DrLex0\/print3D-FlexiRex\" rel=\"nofollow noopener\"\u003e\u003cstrong\u003eits GitHub repository\u003c\/strong\u003e\u003c\/a\u003e where you can find the latest updates, the model's history, and detailed instructions.\u003c\/p\u003e\u003cp\u003e\u003ca target=\"_blank\" href=\"https:\/\/www.dr-lex.be\/3d-printing\/models.html\" rel=\"nofollow noopener\"\u003eGo to my site for an overview of my other models\u003c\/a\u003e.\u003c\/p\u003e\u003ch3\u003eAttribution:\u003c\/h3\u003e\u003cp\u003eThis is a remix of Kirbs' Flexi Rex (\u003ca target=\"_blank\" href=\"https:\/\/www.thingiverse.com\/thing:1759297\" rel=\"nofollow noopener\"\u003eThingiverse thing:1759297\u003c\/a\u003e), based on airfish's remix (\u003ca target=\"_blank\" href=\"https:\/\/www.thingiverse.com\/thing:2189652\" rel=\"nofollow noopener\"\u003eThingiverse thing:2189652\u003c\/a\u003e). That model in turn was most likely inspired by the ‘Flexy Rex’ by zheng3 (\u003ca target=\"_blank\" href=\"https:\/\/www.thingiverse.com\/thing:929413\" rel=\"nofollow noopener\"\u003eThingiverse thing:929413\u003c\/a\u003e).\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eThe reason why I made this version is that my print of Kirbs' original model was not very kid-proof: one of the links broke after some rough handling. Hence I made all links more robust. This means this model can probably be printed even smaller than the original ones before the links become too weak. Of course you can also scale it up at will.\u003c\/p\u003e\u003cp\u003eI have further tweaked the model to be more balanced: it should be less inclined to face-plant than my previous version or other remixes of Kirbs' original model. Also, balancing the model on its tail should be easier, although success still depends on your particular print settings and accuracy.\u003cbr\u003eIf you want to print this larger than your printer allows and don't mind some manual assembly, try the \u003ca target=\"_blank\" href=\"https:\/\/github.com\/DrLex0\/print3D-flexirex-separate\" rel=\"nofollow noopener\"\u003eseparate parts version\u003c\/a\u003e.\u003c\/p\u003e\u003ch3\u003eNote to anyone wanting to sell this:\u003c\/h3\u003e\u003cp\u003eYou \u003ci\u003ecan\u003c\/i\u003e sell prints of this model without having to ask explicit permission, but you must honour the \u003ci\u003eCreative Commons - Attribution - Share Alike\u003c\/i\u003e license. \u003ca target=\"_blank\" href=\"https:\/\/github.com\/DrLex0\/print3D-FlexiRex#license-clarification-read-this-before-contacting-me\" rel=\"nofollow noopener\"\u003eSee the GitHub page for detailed instructions\u003c\/a\u003e.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e(And yes, if you see other copies of this model on this site or others that do not refer to this original, either through the GitHub page, the old Thingiverse page, Printables, or this very page, then they are violating the \u003cstrong\u003eCC-BY-SA\u003c\/strong\u003e license indeed.
