Window blind front clip by jungletech - Thingiverse

I have printed several versions of these in Inland PLA+ and Inland PETG+. All have come out perfectly using standard settings on my P1S using an AMS unit. It's recommended to use PETG due to the UV degradation issues with PLA. This will fit a 2.5" front valance for a Home Depot blind.
