Voron top panel lights and filtered exhaust
Description
These are two separate designs for the top panel of a Voron 2.4 300. One is for a filtered exhaust system and the other one is a design for lights with a cooling channel. The filtered exhaust system consists of two pieces on the top where the carbon filters are inserted and a fangrille to prevent the filament or filament tube to go into the fans. For this design you need: - 2x 120mm fans (I used be quiet! Silent Wings 3 120mm PWM high speed fans) - carbon filter mat - 8x M3x30 screws with nuts and washers Installation is pretty simple, put everything together, cut the filter mat to size and get the wiring to your control board. With the light system, the wires can be hidden pretty simple. Note that with this design you will lose a few cm in build height since the fans are on the inside! If the filters push the sledges upwards i suggest using some additional tape to hold them in place. The light system consist of the cooling channels and the LED trays. Additional parts you need for the light setup: - 8x 1W/3W/5W LEDs on star shaped PCBs (I used 3W but they won't get 3W of power since they need to be split up onto 12V) - 2x 40mm fans (I used Noctua NF-A4x10 FLX 12V, in any case once the light is on you will hear the fans) - 8x 40x40x11mm heatsinks - Thermal glue - Superglue or 2 component glue - Wires (at least AWG24) - Most likely a relais to activate - 12x M3 screws (10mm with inserts, 15mm+ normally) and washers - Optional: M3x6mmx5mm threaded inserts for the top panel - Optional: Dupont connectors First, some wires need to be soldered on the LEDs. I used some dupont connectors at the ends to make my life easier if I ever need to exchange a broken LED. After that the LEDs can be glued onto the trays and installed onto the panel. I used some tape to hold them in place. Then you need to do the rest of the wiring. 4 LEDs need to be connected in series, which can then be connected in parallel to the other 4 LEDs that are wired in series. This needs to be done for it to work with 12V. For 24V you can just wire them all in series. The wires can be passed through the cooling channel exhausts (this need to be done before installing the channels themselves!) or inside the cabinet. The wires of the two 40mm fans also need to be wired in parallel to the LEDs. If you decide to go with the filtered exhaust system you can make some holes for the connectors of those fans underneath the cooling channel to hide the wires. Note that you need to wire them out of the cooling channel separately! After the wiring is done, first run a quick test! If the test was successfully, the thermal glue can be applied onto the LEDs. Then the heatsinks can be put on the LEDs. After that, the cooling channels can be installed. In order for this to work, the thermal glue must not have hardened so that the heatsinks can still move. Be careful not to squish some wires when putting this mess together :P When everything is installed, you can do the rest of the wiring with a relais. That depends on your config though. For both of those systems, there are some printable ziptie anchors. Be careful with how much pressure you put on them though! There are also some drawings to make the corresponding holes. I also included all of the FreeCAD files if you want to make some changes. Check out my designs for more Voron 2 stuff.
