3D printing

At last I bought a 3D printer, a kit with Delta construction. My main use of this 3D printer will be to make adapters that I need to my astronomy equipment.

Adapter 90 degree:
3D printing an adapter to the polar scope to attach a camera 90 degree angled viewer:

If you want to make your own special designed 3-Printed items you need how to make CAD drawings. I have documented my work, you can use it as a tutorial, but you also need to watch tutorials on YouTube. Note: this is new to me, my later attempts are more correct.

These drawings I have made with the FreeCAD software:

I have recently added some STL files for you to download if you find it interesting to 3D-print them. But note: these files are in a very early development. I have also added some updates to correct errors in them that I found when I 3D-printed my own. The new updated files I have not test 3D-printed yet. They have the 7Z format (ZIP).

You use them at your own risk !

To do list:
EQ6 latitude adjusting improvement.
New focuser mechanism to TS130 3" focuser.
Enclosure triple voltage regulator.
Tube rings Yashica 400 mm lens (guide telescope).


DCPMBL motor for direct drive mount:
Just some thoughts how to 3D-print a brushless, permanent magnet electric motor for a direct driven mount. Direct drive means that there are no need for gears:

Sight for telescope:
When aim the telescope towards the stars it could sometimes be useful to have a simple sight attached to the telescope.:

Our IGF Copenhagen gas oven has got broken knob's scale rings. They were difficult to find new and I have designed a new one for 3D-printing:

I have found that they no longer manufacturing the turn signals of my Chrysler Crossfire. In an attempt to fix this I have designed an adapter that can hold a modern certified LED turn signal:

It's a bit difficult to put on the front cover on the Pentax 645 300 mm lens. I designed a new one that fits better:

Viewfinder cover:
It's designed for my Canon EOS 6D, maybe it fit other Canon EOS DSLR cameras as well. It's important to cover the viewfinder, you don't want any light coming in through this hole:
