Thermocouple junction box
thingiverse
This is a junction box for paperless recorders that use Omega thermocouples (SMPW/HMPW series). It fits up to 30 thermocouple sockets which is a common number for the widely used Yokogawa recorders. You don't need to buy a frame to keep them in place; this is being done by the box after attaching the lid. You'll have to obtain 9 pieces of M3x10 screws; preferrably some with a coarse thread and a countersunk head. Here's the type of thermocouple sockets that are supposed to fit in my box: https://www.omega.com/temperature/pdf/SMPW_SMP_HMP_HMPW.pdf edit: Due to request I added a quick & dirty edit for 20 thermocouples. I didn't print that one so there's no guarantee on this one.
