The Orca page is quite long, so I may list here alternative parts for the v0.20 for a moment (and maybe merge them with the page later).

Goals

As I said on my review, lets add some improvements :) (http://forums.reprap.org/read.php?152,94557,94557)

Now I'll tend to opt for the v0.30 but I wanted to convert some parts just for the sake of making it as printable as other Repraps.

• design printable parts of the actual thick/thin sheet (more self-replication)
• redesign some printed parts to ease the build (e.g. in the Y-axis two parts could be one, and thus we don't have to check the distance between them, other can be fused together)
• make a version with bushings or linear bearings (that will greatly simplify the design).

The files will be in .stl and .skp (I think the shapes are doable in sketchup, favoring futur reuse)

Alternative parts

Thick sheet

Drop-in replacement of the actuals cutted parts (and then we may replace them by other simpler/fewer parts)

• File:Orca 2101 z-support-plate 2off.stl
• File:Orca 2102 bearing-support-plate 4off.stl
• File:Orca 3104 yz-drive-plate 2off.stl
• File:Orca 3105 yz-side-plate 2off.stl
• File:Orca 3107 y-frame-endplate 2off.stl
• File:Orca 3111 y-motor-plate 1off.stl
• File:Orca 3201 y-frog 1off.stl
• File:Orca 4002 x-motor-plate 1off.stl
• File:Orca 5001 extruder-base-plate 1off.stl
• File:Orca 5002 extruder-motor-plate 1off.stl

• ORCA_2001_Z_FLOOR
• Orca_6001_mainboard

• alu printbed don't included (for obvious reasons)

Z support

Probably based on something like that : http://www.thingiverse.com/thing:9864

File: stl/sketchup

The LM8UU linear bearings variation

Comparison

(I will try) a comparison, because sometimes it will be less parts and less vitamins, but more plastic, more complex parts, etc.

Total difference :

Addition

• x parts
• xxx gr. of plastic

Savings

• 3mm Aluminium (4pc - total area needed roughly: 80x80mm)
• 4mm Aluminium (15pc - total area needed roughly: 300x550mm)
• 6mm POM (1pc - total area needed roughly: 94x365mm)
• 12 M4 washer
• 6 M4 Nylock
• 6 M4x16

Alternative Build Order

With all these new parts I suppose it will be preferable to edit the build order

Fork Naming

Just a thought:

Sells Mendel - Prusa Mendel / Orca - Orc (less parts)

RP Orca vs TS Orca (repraped parts vs thick sheets)

Bah, will see :p
