A simple, easy to print fan duct for Tevo Tarantula.
According to http://www.desiquintans.com/coolingtests2 and http://www.desiquintans.com/coolingtests, blower fan seems like the way to go, so I chose dual blower for evenly-distributed airflow (surround-style is rarely symmetric nor provides even air in practice) and medium nozzle open.
This is a modified Y axis block front, drop in replacement.
usable with LCD
inspired by aaron alignment stick design
Work in progress
Had a BQ Prusa i3 laying around that never worked with the Witbox extruder. So I decided to modify something to make a Bowden setup.
You can use any extruder, but the one I included is just a mod of the Thingybot extruder. It uses a MK7 drive gear and 608 bearing.
To install the E3D -
Attach the body to the X carriage using two M3 20mm screws.
Place the E3D hot end in the mount
Put the top cover with 40mm fan mount on and screw it into the extruder body using two M3 16mm screws.
Attach the 30mm hot end fan on the side
Attach the 40mm part cooling fan on the front
For the extruder -
Using 3x M3 8mm screws attach the extruder body to the stepper motor
Align the MK7 drive gear to the filament hole
Attach the Bowden push fit connector
Take the idler, put the 608 bearing on it, then add the cap with a M3 12mm screw
Attach the idler to the extruder using a M3 16mm screw
Put a M3 nut into the hole by the filament inlet
Put a M3 16mm screw through the idler and into the nut you just placed
That's it! Just "hang" it like the spool holder that comes with the BQ i3.
You can use the heater cartridge and thermistor from the Witbox hot end on the E3D so you dont need to rewire anything.
You can also splice the fan cables to the 30mm and 40mm fans to make installation easier.
That should be it, if anyone has any questions let me know!
I know this is an old blog post but this is soo cool that i just had to share it! Here’s hoping i can find and collect my own freshwater jellyfish someday!
by Katie Bowell, Curator of Cultural Interpretation
This past week, approximately 150 people in Rye, New Hampshire were stung by the a 40lb Lion’s mane jellyfish (or “jelly,” which is the more appropriate zoological term) that washed up on shore. Lion’s mane jellies are the largest jelly species in the world, and the largest individual ever recorded was over 7 feet in diameter and had tentacles of 120 feet long. The individual who showed up in Rye was described as being the size of a trash can lid and when officials removed it from the water, some of its many tentacles broke off and continued to sting people who came into contact with them in the ocean (tentacles can remain “alive” for 3-4 days after a jelly dies).
Living in lovely, landlocked Colorado, you might think that jellies are one thing you don’t have to worry about encountering, but you’d…
