This is a holder designed for bicycle bags that mount the baggage porter on the bike (like those from Ortlieb). At home those bags usually lie around somewhere and are a bit of a pain to pack when not mounted to a bike. This thing gives you a wall mounted baggage porter for your bags! I printed the brackets with a .5mm nozzle from ABS with a layer height of .2mm. The print came out ok. The overhang doesn't look too good, but it's fine for the intended use. The bracket might look flimsy but worked for me so far: I'm sometimes putting 5kg upwards in a single bag. Only mount the brackets with the rod/tubing on the upper side, otherwise they will break much easier.BoM (for 2 bags):BTW: http://www.ortlieb.de/ bags are great!
