this is simple bosch easygrasscut 23 wall holder its very strong and stiff. if you want it to be more loose you need to make it %1 bigger. i have printed it 3 layers 4 top and bottom %30 infill. its stronger than i expect. also you may use it as bag holder. i think it can hold up to 3 kgs. i hope you like it. doesnt take much time and filament. i have used pla plus hs to print. best regards..
