Wassup dude, so I'm a mod in a Facebook group that focuses primarily on the Kobra standard. We have found replacement parts and added them to this Google doc. Along with helpful tips regarding some of the Kobras trouble points. https://docs.google.com/document/d/19IJDYukagmwTXQ_ApvPc6_TyC-kGGLNYsQa2Wi0JBJI/mobilebasic

But if you don't feel like reading through this whole guide, here are the upgraded belts and crimps that users have used to replace the stock ones.

Good luck, and happy printing!

I had this happen as well and bought these off Amazon.

I found the belt slightly longer then needed, so I bought these to shorten it.

I would recommend buying something like this for the belt, so you can have more spare on hand. https://www.amazon.com/dp/B07PGHTSLT/ref=sspa_dk_detail_1?psc=1&pd_rd_i=B07PGHTSLT&pd_rd_w=7eOR1&content-id=amzn1.sym.88097cb9-5064-44ef-891b-abfacbc1c44b&pf_rd_p=88097cb9-5064-44ef-891b-abfacbc1c44b&pf_rd_r=247AJMDSMQHPQQGYN2D3&pd_rd_wg=IxGZf&pd_rd_r=cd306f21-6bcb-4379-b23b-3cfd9b72271b&s=industrial&sp_csd=d2lkZ2V0TmFtZT1zcF9kZXRhaWw&smid=A4IWNATC64MMF&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEyS1RVVDlLOUo5NkpIJmVuY3J5cHRlZElkPUEwOTU1Mzk1MjhXT09FODZZVFVSUiZlbmNyeXB0ZWRBZElkPUEwNzI5MDQxMjNSOU02U1VUMlVRTyZ3aWRnZXROYW1lPXNwX2RldGFpbCZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=
