Something simple, nozzle.

I apologize for the bad resolution оf photo, broken camera on a mobile.
Drawing is not done according to the rules, it shows only general dimensions...
Part is a test example for washing system, and the test was successful!

Hi.

I recently got access to a 3D printer (BQ Hephestos2) and today I printed two propellers to test the strength of the PLA.

Six blades propeller, intended for high rpm motors (+25k rpm), tested to 10k rpm only:

Two blade propeller that could suit the airplane where the test is performed:

The blade is designed as a loft over several sketches (sections).

Surprisingly, they withstand the rpms and the larger one even produces noticeable thrust :)

Recently I got myself a mini-lathe.
Milling attachments for it can be purchased, but they are a bit pricey. So I decided to make one with a bit of help from 3d printer.

This is the simplest model I've come up with. It allows me to re-use parts of lathe itself. The model is a creative process, so it's a total mess.

Printed of PLA with 20% infill and 3 perimeters. It has just enough rigidity to slowly mill some steel. Not great, but good enough for occasional milling.

Thank you FreeCAD, Slic3r, Repetier-host and PrintBox3d :mrgreen:

Now I need a vise....

Yeah sooner or later you are tempted to produce something you designed in FreeCAD!

This is just a very simple thing: custom hooks to hang my self-made flyscreen frames when they're not in use.

The process, from having one topple over once again and realizing this can be solved to solution took probably about 30 minutes.
