Maverick / ThermoWorks Probe Spool

Wanted a probe spool for my HeaterMeter probes that could be stacked on itself to keep all my probes together. This design consists of one base part which is printed once per probe, and and end cap which completes the final chamber. The base parts are symmetrical so they can be rotated 180 degrees (alternating probes) or have the probes stack up on each other. Stacking up on each other allows them to trap the probe wire to prevent it from unraveling completely.

Tested with:
* Maverick ET-72/73 and ET-723
* Thermoworks ProSeries

The Maverick fit a bit tight, the Thermoworks are a bit loose. In the OpenSCAD file, there are build plates defined for printing 1-4 probes at once. Printed versions available in [the HeaterMeter store](https://store.heatermeter.com/collections/frontpage/products/probe-spool-for-maverick-and-thermoworks-probes?variant=40966768134).
