Self centering jig for discgolf spin dye

Self centering 3 jaw chuck for spin dye discgolf discs.

Usable with standard turntable or my manual rotating platform, you can use my motorised one, but I think it's too slow for this

BOM:

3x M4x6 or M4x8 heat inserts

6x M3x4 heat inserts

3x M4x16 socket head screw

6x M3x6 or M3x8 socket head screw

Printing:

Supports not necessary, but front plate can benefit from some if your bridges are not spot on.

Can be printed with pla, but I recommend PETG or at least use PETG for jaws or scroll plate, or both. It has better friction than PLA on PLA.

You can use what ever plastic you want for soft_insert but I recommend TPU since it acts like a spring, holds disc pretty well and locks the whole chuck.

Tested with PETG 0.2 layer height, 3 walls, 4 top and bottom layers, 15% gyroid infill.

Assembly:

Use soldering iron to insert all heat set inserts, M4 into front plate, M3 into the jaw carriers

Glue knurl ring to the scroll plate, try to center it as best you can.

Screw backplate and front plate together with scroll plate in-between them. Jaws are marked from first one to third, insert first one into according slot in the front plate and rotate scroll plate until the start of the scroll catches the jaw, continue with second and third one.

Screw in jaw inserts.

You can use a little bit of glue and attach front TPU part of the inserts but friction fit should be sufficient.
