Left Bowden Carriage Hot End with stand offs for BLTouch

thingiverse

These are the lower half of the LEFT EXTRUDER x-axis carriage for the BigBox Bowden IDEX design with BLTouch stand offs added. One version has the BLTouch lined up with the nozzle but is farther away, the other version is closer to the nozzle but offest in both x and y direcctions. Note that the BLTouch mounting holes and square nuts are 3mm, not 2.5mm. This is because I didn't have 2.5mm square nuts. I have printed it but I have not yet built the complete upgrade to the BigBox printer. If you want to look at the design, or copy it and make mods to it, you can find it here: https://cad.onshape.com/documents/58a3aebe176e9a0f88bc1a1a/w/ee452fee115593d4f05f134b/e/911bb2debebcfee6b0ed8867 Print Settings Printer: BigBox Rafts: No Supports: Yes Resolution: 0.250 layer height and 0.4mm nozzle are what I used Infill: approx. 20% Notes: ONLY use supports that start on the printer bed ! DO NOT use supports that can start on the part itself. If you do this, the channels needed for the belts will be clogged with support structures which are not needed. I chose a PETG (eSun) material but I also tried it with both PLA+ (eSun) and ABS+ (eSun) and they all worked fine. How I Designed This I used ONSHAPE with an imported model of the BigBox IDEX Dual Bowden model https://cad.onshape.com/documents/58a3aebe176e9a0f88bc1a1a/w/ee452fee115593d4f05f134b/e/911bb2debebcfee6b0ed8867
