Poop bag side mount for flexi Giant

remix, i needed a poop bag holder i could stick on to the side of my flexi maxi as the maxi does not have the flexi rail

The most lazy remix but i just cut part of the side of to give at flat side to stick velcro on to so that i can stick it to the side of my Flexi gigant, dog leash as it does not have the normal flexi doog bag mounting system 

here printed in prusa PTEG with fuzzy skin on some parts. maybe consider scaling down the lid by  1-5% as its a bit on the tight side
