Summary Printed the spring caliper filament addition found here and wanted to mount it above my titan extruder that's already using this mount so I came up with this, and it fit's great!!! You'll want to cut yourself a 25-30mm length of bowden to put in between the bottom of the calipers into the titan, 2) m3 bolt's or screws, and possibly longer m5's for the mount into the 2040 extruded aluminium due to the added material. 15mm should work fine. Print Settings Printer: Anet A2 Rafts: No Supports: Yes Resolution: 0.2 Infill: 50-70% Notes: Print in it's shared orientation to keep the finished side the one that shows. I used Cura's "Support Interface" to get the great finish on the back side even though it was mostly printed over supports the finish came out amazingly good. the slight underextrusion might have helped that case, but either way I'm impressed. (first time using that option)
