Folger Tech Effector Tower Mount with E3D Lite6 and 3010 Fan

**5/7/2018** I made a few tweaks to the design. 1. The 30mm Fan now fits snugly between two parallel rods. 2. I chamfered the inside edge to give a bit more clearance on the hotend. 3. I added eject holes for the nuttraps in the base, just in case they get stuck when trying to take them out. 4. I removed the Nuttrap at the top and used an M3x22mm screw with a locknut on the back instead. 5. I swapped my default Nuttrap size from 6.4mm to something else. 6. I added wiretie cylinders to each side of the hotend's front, making sure that if you have the cube-shaped portion pointing away from the fan, the wires should go halfway between these on one side or the other. 7. I made the Nuttrap test prints a lot smaller. This effector has a 25mm radius and is designed for an arm width of 40mm. It also uses the E3D Lite6 with the 30mm fan that comes with it. My main goal was to mount the hotend higher than the rod connections, which I did by setting my firmware to 299 height before adjusting the design. I started looking at other designs to add a print cooler fan, but decided to keep things simple for now. Since I'm not using a bed leveling sensor, I opted to stick with the original plan. I was also considering changing to a 40mm fan, but since the 30mm fan works in this design, I left it as is. I started out using https://www.thingiverse.com/thing:1456635 as a guide and was able to copy the design into openscad, but then only used his idea of the rounded base plate. I might look at adding the print cooler channel later. Initially, I used a hexagon shape for the base, but the circular shape gave me better clearance around most of the cube-shaped hotend portion. The hardware I used was: * 2 - M3x22mm Stainless Socket Head Cap Screws with locknuts to hold Bracket on + (Originally used M3x16 when I was using Nut Traps at top) * 6 - M3x22mm Stainless Socket Head Cap Screws with Locknuts for the Rods This design uses M3 Nuttraps for the rod connections and the bracket mount. The hole size for the M3 Nutlocks is probably the only thing you might want to adjust. I used 6.4mm, which is 5.54mm across the flat part of the nut. You can change the variable **M3Nut** in the openscad to adjust this, then set the variable **DisplayPart = 4** to create a new test print. The order in which I installed this was attaching the 6 rods to the effector first. Leave the fan off the hotend and install just the hotend and mount the bracket to hold it in place. Rotate the hotend so the wires will come out the opposite end of the fan. You can then use a wire tie through those two hole mounts on either side of the Hotend mount. I put them on both sides in case your wires don't come out the same direction as mine. The bracket could be a little thinner, but I was initially making that mount go almost to the Base Plate when trying 4010 fans and keeping the air flow more directed at the heatsink. It does look a bit cooler than just a simple cube shape. I created 2 versions of the Effector tower, one with Supports (EffectorTower_WithSupports_3010_Rev40.stl) and one without (EffectorTower_3010_Rev40.stl). The supports worked well for me and pulled right off. I printed these using eSun Silver PLA+, but I'll change to PETG if the plastic starts melting around the hotend. The EffectorTower_WithSupports_3010_Rev40.stl was printed at 30% infill and variable layer heights with the Prusa Slicer. This came out to .71oz and print time of 2:52:21. The support weighed .048oz * 0 - 14.55 .2mm * 14.55 - 32.55 .3mm * 32.55 - 50.75 .2mm The EffectorTowerBracket_3010_Rev40.stl was printed at 30% infill and .2mm layer height, coming out to .18oz and print time of 0:29:55.
