Model Description
Flat, 3-way junction box for Wago 221 series wire clamps. This model is heavily inspired by a design shared by https://www.printables.com/@geroulas. This version features a more rigid hold on the Wago clamps by using a compliant snap-in mechanism and hexagon shape. Otherwise I tried to replicate all the features from the upstream model.

Printing
Wago 221 series is rated to ambient temperature up to 85ºC so a Flame Retardant (UL 94 V0) filament type should be used which also matches the temperature rating of the clamp. PTEG or better ABS are good choices. Do not use CF variants as carbon is electrically conductive.
The lid needs to be printed upside down. No support structures are necessary.
Remixing
use either the attached STLs or the OnShape Project: https://cad.onshape.com/documents/f975c60949c2366f473a068e/w/5ac4209302856b510c29a303/e/968612dffb756501b0102f0b?renderMode=0&uiState=694f146626f810cdc93e246e
