10/16/20 - My CNC shop has had to
pass on increases in the costs of Styrene sheets. They have not done it
for over 3 years. Price
list has been updated. In some cases there has been no price increase
as I've been able to absorbed the extra cost for some of the parts
packages. See my web
page at: www.r2d2-cnc.media-conversions
Updated Shoulder Horseshoe to V2.2 - added/clarified assembly
instructions - this is the first of several overdue updates to the
website. Similar work is also in progress on the R23D - 3D printed
After 3 months of prototyping parts and revising the design, I'm
releasing the Outer Foot Drive & Shell design using .188 thick
styrene. The basic design has not significantly changed. Tab and slot
clearances have been adjusted to make the assembly easier and the parts
assembly sequence has been adjusted to take those changes into account.
I've left the original set of instructions up on the website and
recommend that you review those instructions BEFORE you look at the new
.188 version instructions. As always, if you have ANY questions at all
please ASK! It's a lot easier to clear up confusion before you glue
parts together than it is to try to pry those parts apart after you
find out your guess was wrong.
- I've added some drawings to the
Box Beam Legs Assembly instructions. My design for the legs was done
when .250 styrene sheet was available. When it became unavailable, the
design was converted to use 2 layers of .125 styrene, the drawings
however were not updated. The new drawings are designed to clarify what
thickness, and how many pieces, are being used during the assembly.
11/17/19 - I have converted the
NextGen Frame over to using what I'm calling a Tab Core. No PVC pipe,
No Sliders. Makes it easier to manufacture and assemble. Description here. Since I'm making changes I'm going to solicit suggestions for other changes to the NextGen Frame. One suggestion, made a while ago, is to provide 2 of the dome
drive spur gear. Doubling up it's thickness makes aligning the drive
gear with the mating ring gear easier. Have a suggestion of your own? Send me email:

10/06/19 - My
CNC shop has advised me that they can no longer get sheets of .220
Styrene. The industry has changed, yet again. Several years ago I had
to change from .250 to .220. Now the change will be from .220 to .1875
(3/16 - also called .188). I've been using .188 for a few years now in
new projects where rigidity is required. This change causes problems
for four R2 parts packages: CS:L Eggcrate Frame, The
Eggcrate Center Ankle, The Legacy Center Foot and the Outer Foot Drive
& Shell. Fortunately I've already been developing alternate
designs. The Hex Center ankle replaces The Eggcrate Center Ankle. The SAK Center Foot replaces the Legacy Center Foot. I have re-designed the Outer Foot to use .188 instead of .220. I'm working on the CS:L Frame design.
The Shop has been busy 7x24 cutting Sneeze guards. I have not gotten
parts from them since the beginning of August. It looks like they are
finishing that job in the next week or two. With luck I'll be able to
resume shipping parts soon!
