DIY Popsicle mold (Ponderosa Park Sunnyvale)

To avoid buying new, checking if anyone has DIY popsicle molds that you're no longer using? My toddler's friend brought over some homemade popsicles and now he really wants to try making them himself. I figure it's a fun summer activity and he can come up with creative flavor ideas! Happy to pick up at a convenient time for you; my schedule is pretty flexible. Thank you!
