Minimus Cooler Dial Indicator Holder for Tramming Bed

thingiverse

This is a dial indicator holder fits in the left fan slot of a 4010 Dual Minimus Hotend Cooler cage. Either temporarily remove the existing left fan or place it in the unused fan slot. The dial indicator is a inexpensive Harbor Freight model with a 9.5mm barrel. Just push the dial indicator barrel through the top ring then through the ring at the bottom. Push the indicator all the way down until the dial case hits the holder. The length of the indicator plunger should be hang down just below the end of your hotend. On an ender 3, use the tramming guide in the menu to test each corner. Using the bed adjust wheels adjust the relative position from the first corner to set the position of the remaining three corners. Then go through the automatic bed leveling procedure and save your mesh as usual.
