HCMaker 7 chain hot bed bracket

Main requirement for this to work: your chain must have end segment like on photo (common chain fron china) and this chain must me flexible enough to freely move between surface printer stands on and heat bed bracket

Two versions available: left and right. Right version installed by me and it works perfectly. Left version can be even better in practice - you just need to turn 180 degree heated bed belt bracket. Left version not tested by me.
