thingiverse

**Triple Threat - E3D Carriage Mount** This thing is a comprehensive E3D v6 carriage bowden mount designed for Anet AM8/A8 and similar printers. While there are several good designs on Thingiverse, this one aims to include all the necessary features in one design. It has three 40mm fans: one for the E3D and two part cooling fans. The X belt holder/tensioner and cable chain head attachment are also included, as well as an attachment for a 3DTouch/BLTouch sensor. Connect the two part cooling fans together and then connect them to your motherboard so they run in parallel. **Update - January 28, 2019** I have uploaded the complete assembly step file for those who need to modify it. **BOM:** * 3x 40mm Fan - If your fans have a 3mm countersink, use the "CS-Back-Vent" * 2x M3x10mm Button Head - Probe Mount * 2x M3x10mm Button Head - 3DTouch/BLTouch Probe * 2x M3x10mm Button Head - Chain Head * 8x M3x14mm Cap Screw - Side Fans (If your fans have a 3mm countersink, use M3x10mm) * 4x M3x50mm - Assembly Mounting (If your fans have a 3mm countersink, use the "CS-Back-Vent") * 3x m3x20mm Button Head - Belt Holder * 1x m3x30mm Button or Cap Screw - Belt Tensioner (The Anet A8 has one of these spare) * 14x M3 Nut **Additional required files:** 1) Grab the belt holder/tensioner from this link because it has a no derivitives licence.
