Microscope RMS parfocal extender & M25

Revision 0.6 - RMS male better toleranced, Z axis up, add height and logo, added M25

This is a set of parfocal extenders and adapters for microscope objectives.

1) They have RMS thread, both male and female. It is also called "DIN" thread.
Flange to flange distance (Height, or Parfocal Distance) is written on the name and on the object.

For now, only the RMS 8mm is available. It can be used to adapt old Leitz / Wild objectives to the DIN 45mm.

2) RMS to M25
There is one of 15 mm length (45mm to 60) to RMS 45mm objectives to Nikon CFI, and one shorter, 10mm.

The threads are designed to be printed by a normal, FDM filament printer, with PLA material. Use the best vertical resolution you have available.
It will not need support if you place in the right direction (male screw up). A brim may help. Black color of course, but also green will work!
Cannot be printed with liquid curing resin, due to the "sealed cup" issue.

They are strong enough and work well, just please be careful when screwing them as may cross-thread.

Maybe more lengths or even OpenSCAD code coming in ufroreseeable future.
