Simple PTC Heater bracket.

  • Plate laser cut at SendCutSend.com

  • Material: 0.125" / 3.175mm 5052 Aluminum or 0.119" / 3.0mm A36/1008 Mild Steel

  • I chose Stainless Steel on my first version, and I did actually tap it with a M4 Spiral Tap with Tap Magic.

  • SCS Minimum order is $29, so buy two and share with a friend.

  • You can get two plates laser cut, deburred and powder coated for $30.

  • Holes for the fans are sized for M4 tapping, you'll need to DIY.

  • Alternatively, drill out the holes for the fans and use 4mm Self Tapping Fan Screws.

  • Holes for the PTC Heater are sized for M3 3.2mm clearance, no tapping.

  • Holes can also be tapped by SCS, but the price goes up a lot. 😬

  • Holes on the ends are for 2020 mounting, M3 3.2mm clearance.

  • Fits right on top of the bed rails for a 2.4 Voron.

  • 5015 Fans so there's 5mm clearance, if you need more room both 5mm and 10mm printed spacers are options.

Parts List

  • Spicy Meatball Plate from either:

    • SendCutSend, using the DXF drawing.
    • Provok3d.com https://provok3d.com/product/ptc-heater-plates/?v=7516fd43adaa
      • Choose Version 1
      • I get a small commission on this product from Provok3d
      • The Spicy Meatball plate from Provok3d is aluminum, and doesn't tap well.
      • The 4mm holes for the fan mounts are instead drilled through, and M4 nuts are included instead.

  • PTC Heater, 110V 500W from:

  • 2 x 5015 axial (not blower) fan: 50x50x15mm

    • Suggested: Delta AFB0524HHB, $15 ea
    • Optional: Any from this list from Digikey: LIST
    • Check your favorite dealer retailer to see if they have 5015 Axial (not blower) fans.

  • M4 x 0.7 Thread Tap

    • Only if you get steel or stainless steel from SendCutSend and you intend to tap it. Aluminum is too thin/soft to tap well.
    • Recommended: uxcell M4 x 0.7 Spiral Flute Tap
    • Also get some tapping fluid like Tap Magic, especially for steel or stainless.

  • 8 x M4 BHCS or SHCS, 20mm for the fans. Slightly longer for the Provok3d version with M4 nuts.

  • 4 x M3 BHCS or SHCS, 10mm for the PTC Heater.
