HicTop Prusa i3 Auto Bed Leveling Sensor Mount

thingiverse

This sliding mount makes it easier to level the auto bed for some Prusa i3 3D printers. Some people have used this mount because they find fixed mounts hard to adjust, and it's also easy to make from common screws that most people have. With very small adjustments, you can get the Z height just right for a great first layer on your prints. Since different printer models work with different settings, you can easily adapt the design of the mount by adding a new base and sliding parts that are shared across designs. To put together this slide mount, use a 4-40 screw and a 4-40 nut to create a lead screw and attach it to the bearing block using 4mm cap screws. Screw the sensor into place on the sliding part with two 3mm screws and nuts like before, then install another similar member's design for round sensors measuring 12 and 18 mm in diameter at https://www.thingiverse.com/thing:1354218. You can find all of this slide mount in a downloadable PDF from my thing page which gives you a step-by-step guide on how to assemble it correctly. To make sure everything is accurate, I used TinkerCAD when creating this sensor holder so there was clearance between the mount and the sliding part but be aware that some printer designs may require additional sanding for a perfect fit in your specific design of your printer's auto bed system and assembly requirements to suit all models so take the time to verify its dimensions match your exact design.
