While diving our favorite dumpster: a clutch of more than 300 vintage 7400-series logic chips! Previously we have scored stepper motors to last a life time in this very dumpster.

Twist-strap build platform – friction fit

Twist-strap build platform. Friction Fit – Subtracted 0.10mm from magnet diameter to size the holes. The fit is ridiculously tight and exact. Same goes for center hole for stepper axle. HPDE – cut depth 1mm – feed rate 500mm/min – ⌀ 4.67mm @ ≈ 15k RPM

Shifted slots

Nice fit

Yours truly tightened the screw too tightly and deformed the assembly.

Nice tabs, this time
