These are mandatory as the printhead removes the onboard tensioners
Front idler parts
1 x 5 mm x 36 mm pins (right front idler).
1 x 5 mm x 33 mm pin. (left front idler) I ground down a 36 mm one to save me needing to order different sizes). These pins are available from your local bearing supplier or Aliexpress. Some of the Aliexpress pins may need sanding in an electric drill for a couple of minutes to make them a nice sliding fit in the idler bearings. (In my case i used an electric drill on a grinding wheel). Don't try to use a press as it will damage the bearings.

I’ve remixed the microlight head for several uses:
You’ll need
2x M3 x 18mm to replace the screws through the orbiter to the mount
2x M2 x 6mm to mount the X end stop (no threaded insert)
1 or 2 M3x 8 for securing the back of the mount to the back plate (1 is good enough)
Print:
EBB42 Mount.step
Microlight_back_plate_with_toolboard_mount_holes.step
If you just want the toolhead and not the beacon or other modifications you can do it with just replacing the back plate and printing the toolboard mount.
A very worthwhile upgrade to speed up printing start and perfect first layers (especially on a RatRig500)
Microlight_integrated_bottom_plate_duct_beacon_mount.step
Cpap_Pipe_beacon_clearance.step
These are the files for mounting the Beacon and allowing clearance for the wire up the back of the CPAP duct.
Microlight_Rapido_top_plate_aluminum.step
Add a plastic spacer on top:
Microlight_Rapido_top_plate_plastic_spacer.step
If you don’t want to use an aluminum plate you can either print it in plastic
or use this combined model and print that:
