Linear bearing system for 1" aluminium extrusion

thingiverse

This design is a adjustable friction slide for 1" extrusion commonly sold in america. The stuff is cheap, like $9 for a 2ft length from Mc Master-Carr. The series is called 1010. You also need some 3M Mounting tape and M3 socket head screws. I designed them for a new RoStock build using ANSI parts..... I prefer metric but sometimes they don't carry as large a supply here in the states. Instructions To Make one of these just print out 3 of the 1010 sliders and one of the slider carriages. Slider Carriage III (SC III) is split into two parts so you can print it without support, and SC I is just a basic part that you can use to model your own attachment. Once you have the carriage and the 3 sliders printed you need the 3M EXTREME mounting tape and 6 M3 screws. Place a bit of tape on the flat side of the sliders and cut it so it fits correctly, ( this is important since the tape will need to be smashed down later). Repeat until all three sliders have mounting tape on the bottom then drill out the holes or cut away the tape to clear them out. Next take the three sliders and place them carefully into the grooves in the carriage and use the screws to fasten them in. The screws can be used to adjust the height of the sliders to you can get the correct amount of friction and play in the bearing. Add a bit of lithium grease to the sliders and the aluminium extrusion and build away.
