I’ve updated the Maslow Spindle-Lock Toggle Clamp (rebranded to Maslow 4.x Spindle Speed Lock) to use leftover M3x12 hardware from the Maslow 4 kits as opposed to three different bolt lengths. (original post - Maslow Spindle-Lock Toggle Clamp ) as well as usability and ergonomic adjustments to the design.
The exposed bolts that insert into the grey body gently thread into a choked-down segment of the black plastic toggle to hold them in place. Do not over tighten. The other bolts do not require nuts as they are generally captured by the action.
STL files and printer settings can be found here:
The following image show the Maslow logo embossed second edition ahead of the first edition.followed by the spindle lock seated in a Maslow 4 CNC. Gently rotate the spindle while engaging the toggle until the spindle/collect lock is completely set, then wrench.
Pop and Lock!
