About this model

This a replacement cap/lid system for the Swix insulated drink belt. The stock cap that comes with this product is poorly designed in my opinion, with the threads on the smaller top cap not being large enough so that they strip easily which allows the top cap to pop off unexpectedly at inopportune moments. In my search for a replacement I came across another design on this site ( however it does not have the two cap system that the OEM cap has, which I like because it is easier to drink from the smaller opening. Given that limitation I designed this version, which replicates the functionality of the OEM cap but with more robust threads for the top cap. If you use this be sure to read the Post-Printing notes on sealing and gaskets.
