Gizo Spider Footpads

Given a 3% failure rate for the tiny footprint of Gizo spider legs, I added 5 mm pads to each foot:

Gizo Spider – footpads

A few rounds of successive approximation and one copypasta hit the right spots:

pts = [
[24,-23],[28.5,-7],[29.5,14.5],[20,28],
[-24,-23],[-28.5,-7],[-29.5,14.5],[-20,28]
];

translate([14,0,2.8])
  import("/mnt/bulkdata/Project Files/Prusa Mk4/Models/Gizo Spider/GizoSpider.stl");

linear_extrude(height=0.2)
  for (pt = pts)
    translate(pt)
      circle(d=5,$fn=2*3*4);

Which was enough to stick the legs firmly to the build platform:

Gizo spider – white leg towers

Talk about blank looks:

Gizo spider – black on platform

White filament is particularly susceptible to charred globbing:

Gizo spider – white char inclusion

Which was, fortunately, completely hidden inside the shell.

Extensive testing showed the pads pushed the error rate below 1.5%:

As before, dots of hot melt glue hold the eyes in place.

All’s well that ends well: just in time, too.

SPIDERS……Very Nice………I have a few Rubber spiders I put on the Front table when theUPS and FEDEX Guys come in….They get a bit freaked out.. :)

Trick….No Treat :)

IS that A Prusa Machine ?we have about 5 of his printers…all r2.0 and one r3.0but we have used the heck out of them…just recently got 2 Bambu Labs X1C machines…they do a good job…..and a bit faster, BUT I have not tried the V4 Prusa..

I Can’t see how we ever got along in the 70’s,80’s,90’s…..without them…love the blogs…

  It’s a Prusa MK4, bought just before the MK4S tweaks. The critters mostly serve as test pieces to see how well I understand the PrusaSlicer knobs; the defaults generally work well, which is comforting.
  
  Living in the future is good! :grin:
