Extruder Altimeter

This is stupid, but that's the charm, right?

For giggles, I made a 'working' altimeter for the back of my direct-drive extruder motor, 'working' in that the needle spins with the motor. Looking at the blank back of the extruder motor wasn't cutting it for me.

Pretty simple overall - just a bezel outline, a face printed on a laser printer, and a needle that pokes through to attach to the hub of the extruder motor. Sized to perfectly fit any 42mm wide stepper motor.

Check the depth of the hub from the back face of the stepper motor - mine (the packaged Creality Direct-drive unit) was about 2.5mm deep, but the previous one was 3.4mm. I've included two needles with different length shafts, so hopefully you won't have to adjust or remix one.

Print the altimeter face from either the PDF file (US 8.5x11 size, sorry to those that don't use this paper size) or AltimeterFace.jpg, full-size. Trim the paper at least outside the white outer bezel ring, or simply trim the corners to fit
