I designed these trays for my youngest daughter to hold snacks, milk, and water bottles. The base was tested with the Graco and Safety car seats I own; fit can vary with other seats.
The tray slides back and forth and can be removed for cleaning. Options include Large, Large with a snack divider, Medium, and Small, plus bottle bases with a stop for smaller bottles or a straight-through opening for taller bottles.
Print and assembly notes
- Material: ASA or ABS suggested for higher-temperature conditions. PETG and PLA may deform in a hot vehicle.
- The sliding design can be made stationary with a few drops of CA glue, as described in the source listing.
