version 4.9 of the Smartrap introduced a very useful component that supports the glass bed. Unfortunate for me, this component required the use of 40mm or 48mm motors, which I do not possess. Rather than get new motors, I went ahead and designed an adjustable version. You might still prefer the adjustable version even if you use standard motor sizes - the adjustable version allows for some very precise control over bed leveling.Print out the stls included for this design. Take an M5 screw or threaded rod and use it to attach the top component with the base. Use an m8 screw or rod to attach a 608 roller bearing to the top component. Screw the assembly on to the base board of your Smartrap. Adjust height as needed
