Just some basic translucent PLA filament I have from a while back. It's branded "3D Solutech", I think they list it as natural clear. I can't find where I bought it from but I assume Amazon. Prices vary so much over time though and the listing I see there now is too expensive (some $50 CAD) for what it is IMO. Prints pretty well but it does get brittle on the spool and when I load it up I usually have the last couple of inches break off where I clipped it to the reel for storage.Cool print! What translucent filament did you use?
I suggest just searching for clear/translucent PLA on Amazon and checking out the reviews and customer images. Some clear filament actually looks a bit yellowed. PETG might be a better choice if you have experience printing that, I think it does translucent stuff a bit better than most PLA.
