The clips that hold my old Andersen window's interior wood grill dividers have all been breaking (after 30 years can't really complain). This is a replacement clip, it works well.

However I can't ever get transparent filament to actually make transparent objects, so I used brown filament to be close the color of wood. It is very hard to find brown PETG! PLA may be too brittle and unlike to survive much UV.

The MakerGeeks "Bomber Jacket Brown" PETG was the only brown PETG I could find, thought it's pretty dark (think Hershey's milk chocolate). It also arrived with no vacuum left in the bag and no desiccant. I baked it out and it seems to printing fine now.
