Tronxy cooling (and any other printer with the same setup)

This duct functions exceptionally well and is significantly more compact compared to other models on the market. As long as you have this style of heatsink, it should work seamlessly. The mounting holes for the backplate are precisely spaced apart by approximately 2.28 inches (57.66mm), ensuring that ample room is available for use with your printer. The squirrel fans used in this setup are Evercool EC4014H12E-B models, measuring 50mm x 15mm in class. You may need to trim a bit if your fan is too snug of a fit. The bolts holding the fans in place measure 4mm x 20mm. The bottom screws, measuring 3mm x ?, require drilling out to achieve a friction fit, accommodating a 40mm x 40mm x whatever size fan (10mm in my case).
