Housing for Thermal Safety Cutoff Switch

thingiverse

This enclosure is designed specifically for the MakerBot safety cutoff switch and requires no modifications to the switch or the ToM itself. The enclosure consists of two parts that snap together, with a 0.05mm clearance all around the joining faces for ease of assembly. The base replaces the existing spacers on the switch, while the top cap snaps onto the switch and allows the LEDs to slide right inside. The design includes engraved lettering on the top of the case, but the designer experienced issues with this not showing up in their print. They suggest that it may be due to the small resolution of the lettering being too fine for Skeinforge to handle. The bottoms of both parts also warped and did not print well, which the designer believes is due to Skeinforge setting errors rather than design flaws. The enclosure was based on digital caliper measurements of the Generation 4 cutoff switch and the designer welcomes feedback and photos of successful builds or modifications. The designer has yet to mount their safety cutoff switch inside the housing, as they are still experimenting with Skeinforge settings for optimal printing results. To print this enclosure, the base should be printed at 225 degrees nozzle temperature, 130 degrees HBP, using 1 shell and 50% infill. The top cap should be printed at the same temperatures but with 1 shell and 25% infill for better results. The designer is new to 3D printing but plans to continue experimenting with their ToM and will add more updates as their progress continues.
