My recommendation? Make the pegs in glow-in-the-dark PLA and find them easily each night. This is a reasonable replacement for any missing "long" pegs you may need. NOTE: The peg and hole are pretty close to spot-on, but I'm a bit of a perfectionist, so there may be a v4.2 of the peg with additional compatibility efforts. The striations on the printed peg cause excessive wear and tear on softer plastics if the fit is too snug, and I'd rather not find myself needing to replace the entire set of pegs. As always, comments or constructive criticism is welcome and may be utilized in revisions, derivatives or entirely new creations which themselves would be open for additional commentary. ;-)
