My take on the magnetic PTFE connector!
This connector doesn't need a PTFE fitting, therefore saving you some money and time, no more waiting for your next amazon or aliexpress order (if you happen to have magnets lying around)!
Theres two variants:
Legacy:
- About 5% harder to print without supports
- magnets touch each other (slightly better contact)
- Glue is optional but recommended
Version 2:
- No need for supports or glue
- Magnets have 0.4mm (x2) of filament between them (n35+ magnets hold fine)
- easier to remove the magnets afterwards
- comes with an optional lid(v2b) for aesthetic purposes
It takes about 10-15 mins and the print instructions are pretty easy to follow:
| Layer height: | 0.12-0.2mm (0.2mm first layer) |
|---|---|
| Wall Ordering: | Outside to inside (Cura)/Print external perimeters first (Prusa) |
| Support: | Optional (Legacy) / None (v2) |
| Infill: | 20-25% rectilinear/grid |
| Material: | Any! |
Changelog:
v1.0 (11.01.24):
- tweaked some tolerances
- tested it in my setup for about a month
- Release!
v0.95 (11.12.23):
- Reworked the design and came up with an easier solution
- The old connector is now labeled as the legacy version!
v0.9 (11.12.23):
- Start of development
- Modeled the connector
- printed a few variations
To-do List:
- Make remixes with different magnet sizes (if anyone wants them)
- Improve printability of the legacy version with built in supports or sequential bridging
- Leave your suggestions in the makes/comments section!
