Shelly plus 1/2.5 box and lid for wiring

prusaprinters

<p>This is an enclosure that I designed to hold a Shelly Plus device (1/2.5) and associated wiring in a closed, electrically safe box. &nbsp;The design was inspired on (but not a remix of) https://www.thingiverse.com/thing:4974328</p><p>The inside height has been set to hold 3-way Wago 221 connectors vertically.</p><p>NOTE: Plus 1L or RGB 2W dimmer <i>do not fit</i>. It should be really easy to add support, but I don't need it atm. I wish there was a way to script generating the various variations of the model…</p><p>The lid has holes for screwing on with M3x0.35 bolts, however I am not totally convinced with the threading on the box (it works even on 0.2mm quality but takes a bit of convincing). I run an M3 tap on the holes before using the bolts.</p><p>Each cable entry has slots and a recess underneath to slip in a 2.5mm cable tie to hold the wire in place.</p><p>The volume for the wires is OK for connecting 2 cables, though I'm not sure about using 3 wires yet. I'll try and may need to tweak the model.</p><p>I have variations for 0, 1, 2 or 3 holes at the back, 1 at the front and side slots for fixing against something (let me know and I can share the STL).</p><p>&nbsp;</p><p>PRINT NOTES:</p><ul><li>I printed at 3/4x wall thickness to strengthen the bolt holes, whilst keeping infill at 10%, that seemed like a good compromise.</li><li>I am not convinced about the bolt threads on the box body, so I run an M3 tap down the holes before using them. I recommend M3x5mm button head bolts (see photos).</li><li>The only supports required are for the wire holes - be sure to not set them to attach to the main print too strongly.</li></ul>
