CNC Sensor Cover Remix Without Lettering

thingiverse

I removed lettering from each axis to print them with minimal supports. The original design is excellent but requires printing with the lettering facing up, wasting material on unnecessary support structures. To avoid this, you can print without supports if your cooling system is effective and you use sufficient bottom and top layers to prevent sagging plastic from affecting part quality. I printed mine in PLA due to color availability, though PETG might be a better choice. However, these covers will likely break before the sensor would, so it's not a major concern. I've never encountered an issue where sensors were damaged by impact, but I have bumped them and turned them while they're in use. This could potentially throw the gantry out of square. To prevent this from happening again, I'll make sure to design my print setup with these covers in mind. You do need to drill and tap the sensor mount for installation, which could be simplified by redesigning it to have an extended outer mounting piece that bolts together with a separate part on the other side. The existing mount is still easy to work with, though - I drilled a pilot hole and used Tap Magic along with a Dewalt drill and tap bit, accompanied by an impact drill. After transferring the hole location with a punch, it took around 10 minutes per sensor.
