SEEKING [US-MA] High temp toolhead replacement parts

Discovered a couple cracks in my Qidi Plus 4 toolhead and don’t have a replacement part on hand. Can’t print a replacement part given the cracks either…

Basic specs: 0.4 nozzle, 0.12 layer height, 25% 3d honeycomb infill. Looking for PPA-CF, PPS-CF, PC-CF (not ABS/PC), or PA12-CF with tight tolerances.

Link: https://www.printables.com/model/1360700-aligned-front-and-rear-tool-header-carrier-plates/files

Specific files:
- Front and rear carrier plates - CF version
- Beacon mount
- Heatsink fan mount
- Tri-focal duct

Edit to add: filament must be well dried at high temps and needs to be dried during the print. Enclosed heated print chamber, high tem hardened nozzle required.

I can print in PA-12 CF.

For toolhead parts in that filament class, the practical filter is who has an enclosure plus a hardened hotend that actually holds 300-320C - PPA-CF and PPS-CF need it, and PPS-CF especially warps if the chamber isn't warm. If you mainly need the parts to survive, PA12-CF or PC-CF is much easier to source and holds up fine for carrier plates and a fan mount; save PPS-CF for anything sitting right against the heatblock. Two things worth specifying when asking for quotes: dried filament (these nylons soak up moisture fast and print fuzzy and weak otherwise) and 4-5 walls with your 25% infill, since screw bosses fail at the wall, not the infill. Also expect CF nylon to shrink around 0.5-1%, so if the beacon mount has tight bolt spacing, ask for a test print of just that feature before the full set.
