Tony Nutile is the leader of Mark One printer support at MarkForged. He spends a lot of time printing, both to troubleshoot problems and to test software and hardware updates. This gave him two problems to solve, a need to have a convenient empty spool for testing different continuous carbon fiber samples and a place to keep the most-used tools for his Mark One.
Tony fired up TinkerCAD to create solutions to those two problems:
A nylon spool for testing small amounts of continuous carbon fiber, Kevlar TM and fiberglass.
A tiny tool rack for holding the most used Mark One tools: the glue stick, tweezers, allen wrench and leveling shims
