Bridging test i modelled with the inspiration from "How far can you BRIDGE? by palatis"

there are 2 stl files, one is for smaller printers.

small one tests 10 cm bridging at max. it has a max width of 110 mm. large one tests 16 cm bridging at max. it has a max width of 170 mm.

i recommend using raft or brim. if it fails on the supports abort the print, it won't bridge well. if it fails on the bridges abort again since there is no point going any further.
