This is a repository of active design files for CT PPE Project volunteers. For all communication and announcements, please use our Discord server. This page is just a alternative to pinned files in the Discord channels.
For any matters regarding this page, please contact Kevin OrcaSax on Discord.
Elastic Adapters
There are a few different files in use:
- The primary file for printing in PETG only is ElasticAdapterRemixV2.2.1.stl
- If (and only if) the bottom of your slots are printing narrow, try ElasticAdapterRemixV2.2.1.K.stl (PETG only)
Print Tips
- Layer height
- 0.30mm
- Material
- PETG highly recommended
- Nozzle
- 0.40mm or larger
- Build surface
- PETG can adhere very well and damage some build surfaces. Use painter’s tape if you’re not sure.
- Infill
- Print as close to solid as possible. 85-100% infill. Note that this part will print mostly solid anyway since the side, top, and bottom walls will take up most of the space.
- Other Instructions
- For optimal strength, use 4 walls with 0.40mm nozzle. Larger nozzles probably will work fine with less.
Face Shields
As of April 2020, we are no longer 3D printing frames for face shields. These files are here for reference if we start printing them again. Keep an eye on the Discord channel for announcements.
- Most of us have been printing the 17.5mm Fluted remix of the Prusa RC3 design. We’re not printing the cap, but this is an option to add top protection to the face shield.
- The DShek logos removed version.
- The original source file Prusa Face Shield RC3 is also acceptable. We did not print the bottom piece since the thick visor material we were using didn’t need it.
Print Tips
- Layer height
- 0.25mm (especially if stacking, in which case, use a 0.25mm first layer height as well.)
- Material
- PETG recommended / PLA okay if your brand is flexible enough to assemble without breaking
- Nozzle
- 0.40mm or larger
- Infill
- Prusa recommends 3 walls and 30% infill.
- Platform additions
- Try to avoid printing with raft or brim. The burrs created when removing these are difficult to clean up and can be very uncomfortable for the wearer.
- Build surface
- Adhesion can be a challenge with this model because of its minimal surface contact. If the part detaches while printing, try raising your bed temperature or use gluestick or painters tape. You can also add “Mickey Mouse Ears” to edges facing away from the forehead to increase adhesion.
- Other Instructions
- Refer to our Discord #3dprinting channel for cleaning and delivery instructions.
