End Cap for 3/4" Electrical Conduit Pipe on Mostly Printed CNC

thingiverse

**Update 4/9/2016** Rev12: Option added to cut corner off outside to clear Belt Tensioning part. The first photo shows what this looks like. While waiting on some parts, I decided to design and print some conduit caps. This fits the standard 3/4" electrical pipe. I included the OpenSCAD source if you need to tweak the diameter a little or make it fit the metric pipe. Unfortunately, I couldn't find the specs on the internal diameter of the metric 25mm OD pipe. Looks like it should clear the belts and the hole is sized for the cable that comes with Allted's standard kit. You can leave the hole out for corner pipes, but I'm leaving mine in just in case I need to take those caps out at some point down the road. You can use a 3mm Allen wrench to pull it back out if you print it with this size hole. It might be more difficult to take them out without that hole access. Also, when installing this, if the wire is coming from the other end, it might be easier to put the wire coming from the pipe through the end cap before inserting the cap. I used 21mm as the diameter for my 3/4" pipe which snaps right in. I printed about four or five different sizes before settling on this diameter and profile. I could make this work in the customizer, but if you adjust the diameter, it's kind of a trial-and-error process to get the height of the smushed sphere in the right spot. I might be able to make that a rotated extrusion instead of a smushed sphere, if someone needs more flexibility there.
