Hope M4 mono tools and spacer

I have to service my old Hope mono M4 disc calipers (2004 ?) on my MTB but tools are expensive so designed my own, fitting a 1/4" ratchet. Tested in PET-G, spacer is fine of course but tools for caliper are too weak. Might try very tough resin print.

Spacer is for keeping the pads out without wheels in the bike.
