There are three versions:
- R3 - Uses M3 screws and heat set inserts for assembly (recommended)
- R3b - Uses M3 screws and captive M3 nuts for assembly
- R3c - Uses 5mm x 3mm magnets for assembly
This prints in two parts and then assembled. You will need to modify two 5015 fans.
Parts Needed
| R3 | R3b | R3c | |
| M3x20 button head hex screws (or cap screws) | 4ea | 4ea | 0 |
| M3x8 button head hex screws (or cap screws) | 2ea | 2ea | 0 |
| M3 heat set inserts | 6ea | 0 | 0 |
| M3 nuts | 0 | 6ea | 0 |
| 5mm x 3mm magnets | 0 | 0 | 12ea |
| 5015 fan (need to modify) | 2 | 2 | 2 |
| JST-PA2.0 2P connectors* | 2 | 2 | 2 |
* You can either desolder the leads from the stock fans or you will need to crimp on some JST-PA2.0 2P connectors onto the new fans
High-Level Instructions
- Print these files. This will include a set for both left and right.
- Install 3ea heat-set inserts, nuts, or magnets in each cover.
- Make sure and verify that the magnets are oriented correctly before gluing into each side. If not, you may end up with magnets repelling each other instead of pulling the two pieces together.
- Using side cutters, snip the snaps and screw mounts on the the 5015 fan shrouds. Use a file to clean up the side with the fins. Discard the other side.
- Fan Connector
- If you are reusing the stock connector, desolder it from the old fan and solder onto the new fan.
- If you are not reusing the stock connector, crimp the JST-PA2.0 2P connector on to the new fan wires
- Insert the fan half into the fan shroud.
- Pass the fan wires through the hole in the cover
- Screw the two halves together (not needed for R3c)
- Screw the cover on to the J1 extruder body, making sure to plug in the fan.
