Lift & slider support for pinball feet

prusaprinters

IntroductionThis fits over a standard 3" plastic & foam furniture slider (these are generally labeled as “3-½ inch”, since the hard plastic part is in fact 3.5", while the foam that this lift rests on is usually just under 3" in diameter). It has a recess underneath to fit the foam, and a recess on top to fit the leveler foot. The short one has only ¼" of lift, while the tall one has 1" of lift.Use the short one if you just want to distribute the weight of the foot better and keep the furniture slider from squashing, and then eventually cracking and breaking, as seen in the right-hand slider shown in the cover photo above (note the impression from the foot).Use four of the tall one if you want to raise the whole machine up 1" without having to extend the levelers to their max extension. Use two if you need to compensate for some issue at one end of the machine or the other to get the machine leveled correctly, again without having to extend the levelers to their max extension.Because of the recesses, the lift stays firmly in place with respect to both the slider and the pin leg's foot, with all three parts moving as a single unit when the machine is gently pushed from one position to another on the floor. I suppose if shoved hard enough against some kind of obstacle on the floor, it would be possible to knock the leg from the slider/lift assembly. Use with care!On carpet, even with the lift and slider spreading the weight out, there will still be some slight depression of the carpet/pad. This is enough to hold the machine in place during normal play, but the depression is easily overcome when actually moving the machine around.PrintingI printed this in clear PETG, on a Prusa MK3S+ and PrusaSlicer v2.5.0.Important slicer settings include:Infill 20% for 1" lift, 50% for ¼" lift. I use the higher infill for the ¼" version, because there's less vertical distance along which to distribute the forces. These infills have been working great for me, but it's possible you could get away with less on each.Support style “snug”, supports on build plate only, and print in the natural orientation, i.e. with the wide part at the bottom. Carefully sliding a knife or other thin tool between the support and the part, going around the perimeter to separate, should allow the support to pop right off. If you've been careful and done it right, the support will come right out shaped like a cookie (or drink coaster, if you want to use the scrap :) ).
