A pocket-sized holder with a sliding lid for storing individual eye drop vials. Comes in a small size (holding up to 2 vials) and a large size (holding up to 3 vials).

Highlights

• Keeps your eye drop vials in a sturdy container so that you don't have loose vials lying around
• The lid is able to easily slide open for access but also stay securely shut
• Has a separate compartment for quick access to your last used vial
• Lanyard holes on the front let you attach this holder to a lanyard or keychain

Printing notes

• Print the size that you need: Plate 1 is the smaller version and Plate 2 is the larger version
• The sliding lid works best in PLA because this piece will bend and curve across corners (but it should not break from my testing)
  • TPU does work as well but you may not find the lid closing sensation as noticeable
    • For context, the lid secures itself shut by “jamming” itself into the corner
    • TPU will still “jam” but it also scrunches up unlike PLA which is a bit stiffer
• Ensure that “Detect thin walls” is enabled

Assembly

1. Slide the side of the lid with the knob along the edges of the holder
   1. You can help navigate the lid around the corners by pushing down on the lid as you slide it across the corner
2. To slide the lid off, push down on the side that is “jammed” up in the corner to allow the lid to move

Other notes

• If you find the sliding lid to be a bit stiff, you can flex the lid to help break the stiffness (no need to fold the lid)

• I tested the holder with Systane Ultra PF vials (Amazon link) as they're my preservative-free eye drop of choice but also they are the largest individual vials I've seen so any other vials should fit
