Should be easy enough to fabricate from flat sheet metal. Do them in cardboard cutouts first to check.
You should already have:
- The rack itself and the R3 to measure between the M8 and M10 guard threaded mount holes etc.
- a tape measure or rule
- pencil
- scissors
- the image I provided gives the rough size, scale and shape in relation to the rack.
All you need to do now is finish your box of cereal and make the templates.


Anyone can do the easy work once you have applied those required but available dimensions.
Aluminum or steel whatever is available but if the space available is limited to 2mm or less, I would use steel.
Hand or electric drill, Hacksaw and/or bench / 4" grinder and file.
If your really patient you could even use acid and candle wax!
