Crown / Samducksa 309 Flat Jacket Octagonal Collar Restrictor Gate

As the name implies, this is an octagonal collar for Crown/Samducksa 309 models. Tested on 309MJ but should fit any 309.
Negative numbers at the end of the file names indicates how the gap (throw) was shortened and positive how it was enlarged.

Due to the fine measurements and printer precision settings, 0.5mm differences might not be apparent. I suggest trying even numbers starting from ±0.0 first. Using .stp file format is also suggested due to abundance of round shapes, which are not ideal for .stl files

Compatibility table (assuming default shaft size)

Abbriviations:
?? - Not tested
OK - works as intended: switch activates before gitting the gate
NO - doesnt work: either switch is not activated or the gate is not reached when switch pushed all the way in
MEH - works barely: either switch is barely activated after the gate is hit or gate is barely hit when switch pushed all the way in

Update History

Upd1

Added 309FJCollar_OctaSQ_+0_5mmDiag version, which is an original octagonal version with no throw changes ±0.0 but with wider diagonals by +0.5mm each, which makes diagonals deeper and closer to original Crown/Samducksa's default square jacket. This version does not have size variants.
