Building a Prusa Mendel 3D Printer
Last week I received my Prusa Mendel 3D printer kit from Makergear. I started to build the kit yesterday and after 5 hours here what I have. I guess I still have a lot of evenings to spend on that thing!

Bicycle Quick Release Headlight
I published a new thing on Thiniverse.com http://www.thingiverse.com/thing:13877 This thing is a quick release bicycle headlight using magnets. I bought the magnets in a garage sale so I can’t really help you find the same magnets.
Instructions
Print the parts:
—————-
2 x clip2.stl
1 x magneta.stl
1 x magnetb.stl
Attach one clip2.stl to magneta.stl using a 1/2″ 6-32 bolt.
Attach the other clip2.stl to magnetb.stl using a 1/2″ 6-32 bolt.
Attach the base to the bicycle handle bar using a 1 1/2″ long 6-32 bolt.
Attach the light to the upper part using a 1 1/2″ long 6-32 bolt.
Superglue the magnets on the bottom of both magneta.stl and magnetb.stl
Make sure you align the small notches in the right direction for your setup.
What’s Next
- Would be nice to derive a new thing using more standard magnets.
- Making it in OpenScad would allows parametric parts.
- Adding new connectors to attach a camera, a map, …
Stars Trackers
I posted these two barndoor mounts on Thiniverse a few days ago. One is manually operated while the other is motorized.

Motorized Stars Tracker
Since I have not that much time on my hands, I decided to merge both projects so that I can chose between the portability of the manual version and the ease of use and accuracy of the motorized version.
The new manual version looks pretty much like it’s ancestor with some minor modifications. The length of the device has been cut in half and some minor bugs have been fixed.
New version of the manual Stars Tracker
I am now working at motorizing this new version of the manual Star Tracker. I want to make it simple to switch from the manual to the motorized version by reusing as much parts as possible.
I ended up today with this motor support that should replace the actual wheel of the Star Tracker.
Motor Mount for the Motorized Stars Tracker
I am using the same type of attachments as the frame of the Makerbot. This technique is pretty cheap and allows strong assemblies using plastic and wood.
Next step will be to design a coupling to attach the motor to the 1/4″ threaded rod of the tracker. I think I’ll use the same type of coupling as the Reprap 3D printer.
