I have ordered t-slot, it should be on it way here presently.

So I have printed myself a set of plastics for it also.

In printing these I noticed and interesting effect, this is translucent orange PLA when on the real. When printed Its a lot less translucent, except for the edges, they are still translucent. The edges are printed a lot slower, 30mm/s the rest is printed at 100mm/s. Although it printed fine, it look like at that speed something interesting is happening to the plastic. Since its bonded fine, I dont think is a temperature thing, more air being caught in the print... But this is just theory.

This is also visible in the the left most piece, these parts are mostly perimeter and thus much darker.

Ive had a few more replies from t-slot suppliers.

I have found that

100 * 1.08
sub total  306.87
gst  46.03
TOTAL  $352.90NZD

+ shipping, not mentioned.

Sadly, and not surprisingly, getting it from the USA even with 2/3 of the cost being shipping, is still the cheapest option.

T-slot Aluminum

Ive been trying to get some T-slot Aluminum, as I would really like to build a mendelmax and a few other projects based on this sort of extruded aluminum

Unfortunately It seem like New Zealand is very much still stuck in the dark ages!
This stiff is nearly imposable to get...  Even though we make aluminum!

From the mendelmax site, parts from Misumi:

Part NumberQuantityPrice Ea. (USD/Euro*)Extended Price(USD/Euro)
HFS5-2020-420**6$2.15$13.10420mm extrusions
HFS5-2020-340**4$1.77$7.07340mm Extrusions
HFS5-2020-300**4$1.56$6.24300mm Extrusions
HNKK5-51$19.32$19.32T-Slot nuts for 5mm screws, bag of 100
HTJ54$.49$1.96Self-tapping screws for blind joints


This is in USD.

So first I attempted to contacted Misuni, their web site it separated into geographic regions. New Zealand is part of their singapore site

I attempted to sign up, only to find the site wouldn't allow you to select New Zealand from their Country pull down menu. This was not a good start. Their sign up was also full of company related questions.

I e-mailed their support and after fighting with their engrish I eventually got the reply
"I had checked with our management, sorry to inform you that according to our company policy, we are not able to sell to Individual. We can only lease with corporate company. You cannot purchase our products locally in New Zealand as we do not have any branch, agent there."

I then tried a few local places, while waiting for replies from the other international suppliers listed on mendelmax, "no sorry that’s not one of our standards"  But they did offer to make me some if I wanted a large quantity.  I never found out just how much that was, but it was alot more than the 13 meters I wanted. 

Ullrich Aluminium, "Unfortunatley we have nothing in that size 20x20mm t-slot, our only one is a 57x32mm."

Bosch finally replied that there was none in New Zealand or Australia, but they could ship some to me. I got a quote, $599.10!! +GST +$190 shipping!!!!
Thats $920 odd dollars!!!  I could fly to America and pick it up myself for less than that!!!

I am still looking, but it is most likely I will get a friend to get it from the USA (where misumi will allow individuals to purchase) and then ship it here.
