This is a movable turret for installing a direct drive sprite extruder onto Creality Ender 3. The loom cable passes through the hole left from your old Boden extruder. It enables full extension of the X,Y and Z axis of your printer with very little repetitive motion in one spot of the cable which can cause cable failure.
Revision R1 is a more articulating version were the angle not only changes vertically but horizontally as well. You will have to snap the two pieces together they are fairly tight and will not come apart easily.
Printer:
Creality Ender 3
Resolution:
1.2
Infill:
20%
Filament:
Stronghero3D PETG
Black
Notes:
I Printed in PETG on a PEI bed but other types of filaments should work just fine only use a brim of 15-50 lines or so for good bed adhesion. Filament temperature for PETG was 235 bed temperature 90 degrees.
The push pin ties are meant to go into the bottom of the old extruder base, and up through the new turret base. Pins can then be melted using a solder iron or lighter heating a flat tip screw driver to melt over the top end so it can't release under stress.
Note: Clearances for tolerance for movement require printing at 1.2 line resolution or thickness (layer hight). It will print a little slower but better. You may also have to cut along the bottom circle with exact-o knife to get to release, if you did not choose bim only on outside of model. Sometimes it's pretty tight but if printed at the correct layer width and line height 1.2, it will release.
Printing in PLA may require a raft for the flap of at around 5mm - 15mm. the roundness of the Flaps bottom piece is inconsequential to performance.
Have fun with this project and don't be afraid to innovate and incorporate. Its also nice to tip the designer if you like and use their art and innovation.
