Parametric 3 x 40mm fans and led effector for e3d v6 (Delta/Kossel)

thingiverse

After a lengthy search, I was unable to find a printable part for my DIY delta 3D printer that met these specific requirements: 1. Easy to print (no supports, rafts, etc.). 2. Easy to mount and unmount. 3. Utilizes three 40mm fans for cooling (quieter and better airflow). 4. Provides a clear view of the printing surface (able to see the printer nozzle and layer layout). 5. This means light, so I included ultrabright 5mm LED support (x2) near the printing surface with unobstructed lighting. 6. A mechanism for easily adding modules (probes) via a hookup system. 7. Parametric design in OpenSCAD for easy adaptation and tuning. After several iterations, I reviewed all characteristics, so if you don't agree, please comment; I'll try to improve the design. The only drawback is that you may achieve better temperature control by using a silicone sock over the heater block. To assemble this part, you will need: M3 bolts: 4 x 16mm for the effector (I use only four), and 4 x 25mm for fans with 8 nuts. 2 x 5mm ultrabright white LEDs (and resistors, wires, etc. to connect to your system). 1 x resistor (1K 1/4W for 2 x 3v 0.02A -20mA- in series, 24V power supply). Version V1.1: Different holes are provided for the anode and cathode of the LEDs. A slightly larger hole is included for easier LED embedding. Please share any improvements or thoughts you may have.
