Sports chain, Chain Links

Boost MeBoosting is free if you enjoyed my print or model help a creator out with a big thanks and a boost!!! Thank you soo much for your support!!

UPDATE 7/7/25- 

New STL uploaded one side is a little flatter then the other this side goes down on the build plate, Should fix adhesion issues, I also will upload a new print profile thats 15 links at a time of this new style no brim required!! Thank you for all the boost & comments to help with the adjustments! 12% infill is all thats needed, you can bump it up if you want but so far I haven't seen an issues, slowing down the first layer also helps with adhesion issues.

 

Sport chain links, I had multiple people ask me about the link I use for my chains well here they are!! Put them up as a separate link to download, the links go together at a 90 degree angle and then don't come apart very easily.  I designed it to lock together tightly and lesson the chance of them coming apart!

 

*****As of 7/7/25 model doesn't need drop down -.2 layer height****

 Printing slower does help because the first layer is the most important on these once you pull the link into your slicer drop it down -.2 will almost make it perfect, also the outside is very rounded so helps going slower. I have also had more luck using adaptive layers in cura not sure what it is in bambu labs, 15% infill should be perfect on these bump it up in Silk PLA to prevent cracking when assembling.
