Mods are often what makes a Voron 3D printer special from a typical stock build, assuming yours didn’t come with some already. However, not all mods fit both the Voron Trident, and the Voron 2.4, and some are meant for the Voron V0 or other Printers for Ants printers. There is a lot to choose from. Not only on the Voron mods github, but Printables and Thingiverse as well. So hopefully this list helps you find something that may be to your benefit.
Notes about filament choice
Most interior parts, unless specified otherwise, need to be printed out of ABS or ASA, preferably not ABS+ and definitely not PETG or PLA. PCTG is a maybe but not anything under tension. PC is an alternative to ABS if push comes to shove.
Auxiliary cooling

This mod adds auxiliary cooling for your voron 3D printer, helping to cool off PLA faster, as the Stealthburner is not the best for PLA. The most common printers to do this on are the Voron Trident and Voron V0, as their gantries are static. There are mods for the 2.4 but I question their effectiveness.
There are a few mods for the Voron V0 and Trident that add some powerful auxiliary cooling, these use large blower fans mounted at the bottom of the printers with ducts running to about level with the nozzle. They are pretty easy to wire, not much difficulty is added by using mains-powered fans either. And they massively improve printing with PLA or anything else that likes part cooling. There are mods for the Voron V0 and Voron Trident on Printables.
The mods for the Voron 2.4 I question the effectiveness of. While they very likely also work for the Trident, they use 5015 fans to help cool the part. You have cooling that goes from the sides as well as the back of the gantry. You may get more power out of them by overvolting 12V fans to 24V, but not all 5015s tolerate that.
Different extruder

The default stealth burner extruder is basically a BMG but with a NEMA 14 motor. There are other designs out that that’ll give you more pushing power, or fix a banding issue that the default one has. One, in particular, uses LGX or HGX gears as well as some with a gearbox. Those last two in particular are for the full-size StealthBurner. The mini StealthBurner, as well as other Voron Toolheads like XOL and Dragonburner, use standard extruders like the Sherpa mini or the orbiter.

There are quite a few different toolheads for Voron 3D printers, particularly the Voron Trident and Voron 2.4. Those of note Are the XOL and Dragonburner, both of which are lighter than the stock Stealthburner. There are other options, MediaMan has mounts for the Hero Me system for the Voron V2 and Voron Trident, it can mount to the linear rail, though it is rather heavy and doesn’t support toolhead boards. There are also mounts for the EVA system, RatRig’s toolhead, on Voron 3D printers.
As for the Voron V0, you’re pretty much limited to small toolheads like the Dragonburner and its family.
CPAP Part Cooling

This kind of part cooling not only brings weight off the toolhead but also increases part cooling effectiveness massively. Some stick the CPAP fan outside the enclosure but it might not be a bad idea to stick it inside the enclosure if you’re doing higher temp printing There is a mod for just the stealthburner with the CPAP cooling or alternatively a custom toolhead that’ll create a vortex of air though the latter only work with klicky, and maybe TAP. As for the Voron V0, I’ve seen it done before but I haven’t found any mods for it.

If you’ve heard of Prusa’s MMU unit before, some of these are a lot like them, but they have more slots than the typical MMU or even the SmUFF. The main two would be the TradRack and the ERCF. These MMU units allow for multi-color printing on just about any Klipper printer, but on their own it takes quite a bit of calibration. You need to tune a ramming procedure or put a filament cutter mod on your tool head, and you’ll most likely need a filament buffer.
The ERCF maxes out at 12 colors but the Tradrack can have as many lanes as you can fit, with the Default being 14. There are a few sellers of ERCF kits but, as of writing, only TriangleLab sells a Tradrack kit.

Danger Klipper has a slew of features that the mainline Dev often didn’t merge. In its default branch, there’s a version of the coreXY kinematic that has different accelerations for the X and Y axes; a more accurate, but more noise-prone, PID version, PID profiles, and support for a new MCU as of writing. The branch ‘bleeding-edge-V2’ has some experimental, but also resource-intensive, features. Some features of that branch will likely require a Klipper host with an x86 CPU or something like a RockChip CPU and anywhere from 2-4 GB of ram. Namely PA sync with input shaper and input smoothing. Noncritical MCUs and MPC will likely work on a typical host.
It’s not hard to switch branches if you’re using KIUAH. Just add ‘DangerKlippers/danger-klipper’ to a file called ‘~/kiauh/klipper_repos.txt.’
Voron Belt Kit

Adivita3D’s Voron belt kit is perfect for printing farms, but it has a few downsides. For one, it only works on the 350 model 2.4, as well as the Troodon of the same size. Secondly, your printer won’t be as enclosed as a typical 2.4. Third, some mods don’t work with it, particularly if they need to go on the underside of the gantry.
The belt can also be tricky to tune, both in tension and Z offset, particularly with TAP. For tension, it’s a good idea to heat the bed to 110C and adjust until the belt can move without binding; this may need further adjustment once a print is on the bed though. Z offset is like tuning it for any other printer, but you need it to lay down and not smushed into the belt, otherwise it won’t release from the belt once the belt moves.
Conclusion
There are quite a lot of mods for Voron printers. Not just in the official mod repo, but also on sites like Printables. You do need to look and figure out what is compatible with what though, or design it yourself. Hopefully, this mod list notes out anything useful to you to help improve your Voron.
