5015 Blower HEPA Exhaust for Voron Trident

This model pairs with Cliftoce's Voron Trident Horizontal Umbilical Chain. It runs much quieter than stock, at around 38dB.

BOM

For fastner sourcing, I've found the following to be good places:

• AliExpress – slow delivery ~2 weeks
  • Screwhome SHCS / BHCS / FHCS – Good selection, on voron sourcing list
  • Nindejin SHCS / BHCS / FHCS – I think I saw them on the voron sourcing list
• McMaster Carr – pretty expensive
  • SHCS / BHCS / FHCS

As for the parts needed:

• Fastners
  • 4x of M3x6 FHCS
  • 2x of M3x12 BHCS or SHCS
  • 2x of M3x20 SHCS
  • 4x of M3x25 SHCS
  • 4x of M4x20 BHCS or SHCS
  • 2x of M3 half-round roll-in nuts or hammer head t-nuts
  • 10x of M3x4 Heat set inserts (Voron-style)
• Fans & Wiring
  • 2x of Wago 221-413 Lever Nuts
    • West3D
    • KB-3D
    • Platt
  • 2x of 5015 blowers (GDSTime, Delta), ideally 6000rpm 24v
    • GDSTIME GDB5015-A, 6000rpm 24v
      • West3D
      • KB-3D
    • or Delta BFB0524HH
      • West3D
      • KB-3D
      • Digikey
• Filter
  • 1x of 800/900 series iRobot Vacuum filter
    • note: the high efficiency filters are cheaper, but my understanding is that they don't filter as much
    • amazon
• Optional
  • 6x3 cylindrical magnets

Assembly

1. Get your CAN umbilical and bowden tube set up from Cliftoce's model
2. Install the M3 heat-set inserts into
   1. Fan Duct - gets 6
      
   2. Filter Inlet Duct - gets 4
      
3. Use 4x M4x20 bolts to bolt the 5015 blower fans to the fan duct
4. Mount the Wago 221-413 lever nuts into the sockets
   
5. Stack the filter housing, and filter inlet duct onto the fan duct, then bolt three of the M3x25 and both of the M3x20 SHCS bolts in to hold the sandwich together, leaving the left M3x20 a bit loose
   
6. Position the hole in the filter housing lever in line with the remaining hole in the filter inlet duct and then install the remaining M3x25 SHCS
   
7. Cut the motor wires, connect them to the Wago connectors (pairs of black to one connector, pairs of red to the other), make sure the bundle will fit under the fan lid
   
8. Hold the assembly up to your exhaust hole and determine how much wiring you need in order to connect to your controller. I suggest running along your top rail to the left (looking at your printer from the front), down the rear left rail, and through the wire inlet on that side. Cut the wires to that length then connect them to the Wago connectors, then run them through the channel in the assembly.
   
9. (optional) Zip-tie around the wires, before they go into the wire tunnel / channel, to secure the wire from pulling through the channel in the assembly
10. Use the M3x6 FHCS to bolt the foundation mount to the assembly, running the wires in the channel and being careful not to pinch them
    
11. Tuck the wires through the exhaust opening and then use the M3x12 BHCS bolts and the t-nuts or roll-in-nuts to bolt the assembly to your rail, slide to the right of your exhaust opening
    
12. Route your wires to your controller and plug them in
13. (Optional) install 6x3 cylindrical magnets in the assembly and fan lid
14. Slide the fan lid over the blowers, being careful to make sure the wires don't get pinched and the Wago levernuts don't open
15. Open the housing lever and slide your filter mostly in, then use the lever to secure the filter into place

Fan Options

Using the 6000rpm 24v option, I measured around 38dB with my setup.

My design was built using the for the Delta BFB0524HH model, but I ended up going with the GDSTIME GDB5015-A 6000rpm 24v since I already had one. They're slightly different profiles but I made sure that the GDSTIME one would also work.

Here's the RPM / volts / noise breakdown for the GDSTIME options:
