As part of my own self-education on 3D printing I designed and built following two kinds of 3D printers (and since December 2020 three additional designs in draft-stage):

I designed and built Ashtar K and Ashtar C using OpenSCAD in a strictly parametric manner and optimized it so I could use a single beam length to compose the 3d printers: 500mm 2020 aluminium profile.

Back in February 2018 I bought the CTC DIY I3 Pro B and began later to design Ashtar K, and printed the first parts with the CTC for the Ashtar K 1. A few weeks later Ashtar K 1 and CTC printed parts for the Ashtar K 2. In fall of 2018 I began to design Ashtar C, and printed parts with CTC and Ashtar K 1+2. In February 2019 Ashtar C 1 was functional and printing.

The principle to print parts with 3D printer for another 3D Printer is called RepRap: Replicating Rapid-prototyper.

Drafts

In December 2020 I started with two three new designs:

Transformations

As I work with 500mm T-slot and V-slot 2020 alu profiles I can easily transform between:

Type	Beams	T-Slot	V-Slot 1)
Ashtar K (Prusa i3)	11	10	1
Ashtar C (Core-XY)	17	14	3
Ashtar M (Prusa i3 MG)	10	7	3
Ashtar D (Classic XY)	17	14	3

Footnotes:

1. Alternatively V-Slot beams can be replace with linear guides + T-Slot for higher precision.

So with 3x V-slot and 14x V- or T-Slot 2020 500mm following of the Ashtar Series such as K, C, M or D can be implemented, as I intended from the very start with Ashtar K in 2018 to go for uni-length 2020 alu profiles – now it pays off.

Continue with:

• Ashtar K (Prusa i3)
• Ashtar C (Core-XY)
• Ashtar M (Prusa i3 MG)
• Ashtar D (Classic XY)
• Ashtar B (Cantilever)

That’s it.
