This is the Snapmaker J1s with the top hat installed. The design is, and is not, original. It was inspired by a number of other top hats others have created. It was printed entirely with the J1s. The top hat magnets to the base and the orginal top magnets to the top hat. For ventilation, it has two 12v 60mm fans at the back and vents on the sides. There is an integrated temperature/humidity display and a switch for the fans on the front. The back panel also has raised feed-through guides for the filament, a 12v power jack, and USB connector to connect to the camera. The bottom edge of the panels have raised slots to strap cabling to.
The camera mount is visible at the top of the doors and was printed with the orange Snapmaker PLA that came with the printer. It holds a modified Microsoft LifeCam 3000. The flexible mount on the camera was removed so it would fit the in confined space.
There is a small form factor Windows 10 Pro machine that is used to slice and send gcode files to the printer. It is connected to the J1s with a USB cable, but gocde files are usually transferred directly over wifi from Luban or Cura. I have used Prusa a few times for slicing as well. And, in that case, I use the Windows version of OctoPrint to print over USB to the printer.
The system is powered using an APC UPS as we lose power at times due to wind storms in the Fall and heavy snow in the Winter.
These are the mods I have made to the J1s:
- added a top hat that includes fans, venting, temperature/humidity readout.
- changed to Haldis 3D Mk8 plated nickel on copper nozzles.
- added extra heat sink compound to the heat break.
- replaced the top 90 degree extruder guide to a straight guide with a ptfe fitting.
- replaced the ptfe filament guide tubing to 3mm id.
- added a rounded guide for the x axis cables.
- added a USB camera to the front of the enclosure.
