Photon build plate leveller, reinvented

thingiverse

Did my own, modelled on the ANYCUBIC PHOTON Easy Leveler by wundel, thing:3096818, but remade in OpenScad, and uses captive M3 nuts for the clamps, through which I put M3 cone-tipped grubs. Enlarged countersunk holes for flush finish. I printed in nylon, PETG and resin (all solid). All seemed fine. I don't like the Zero==Home thing, as it hits the resin quite aggressively, so I just level as normal and reap the benefit of it hopefully being more robust than the ball clamp (is that really what it's called?). I noticed that tightening the side bolts can displace the plate bolts slightly, which seems like a universal problem for this design, so I've made another change. There's a V2 STL here now, which has slots to drop in small metal push-plates. This means the side screws will push against those, removing any twisting effect. I'm using those electrical spade connectors.
