Monoprice Wanhao Maker Select i3v2 Spring Cups

thingiverse

None of the cups on Thingiverse fit my springs, and I'm not sure if mine are different from the Wanhao ones - maybe they were all too small by a lot. So I made my own cups. I had to print them at 103% (on x and y only leave z at 100%) because they need to fit loosely and not restrict the springs or they will inhibit their movement on fine adjustments. Clean up the inside also if your printer is a little sloppy. These cups will keep the springs from tilting and bending, which will throw off your bed level. I made them 7.3mm tall, which is a little smaller than the spring fully compressed so they won't interfere with its movement or compression as long as they fit loosely. Both holes are beveled; you won't really see this unless you print at high resolution. Print Settings: Printer: Monoprice Maker Select i3v2 Rafts: No Supports: No Resolution: 0.2mm or better Infill: 100% Notes: Infill is 100% but it's small enough that I don't think infill settings will matter. Post-Printing: Make sure the spring has a clean loose fit, no wiggle but also no resistance. Use a knife to clean up the inside wall as well. Put the spring in and compress several times; make sure there is no resistance. You're ready to go. Going 104% might remove the need to clean up; just make sure you change both x and y equally and don't change z. I designed this by going into Tinkercad and starting to make cylinders. I imported my own custom cylinder from 3ds Max to bypass the low-polygon nature of parts made in Tinkercad. I used a parabolic cone to make the bevels. The hardest part was calculating where to place the parts relative to each other before cutting - there's no "center" option in Tinkercad.
