OpenBeam Kossel lengths are end of line

MakerBeamXL will replace the black anodised OpenBeam Kossel longer lengths (750mm, 360mm) once these are out stock. The clear anodised version and the shorter lengths (600mm and 240mm) will not be replaced.

Due to disappointing sales we made the decision to stop selling the shorter lengths that are meant for building a Kossel printer. The 600mm OpenBeam black (100685 – already sold out) and clear (100832) anodised and the OpenBeam 240mm black (100641) and clear anodised (100809) are end of line.

For the longer lengths (750mm and 360mm) we made the decision to offer these lengths in MakerBeamXL black anodised. These MakerBeamXL Kossel lenghts will only be available in small numbers. The MakerBeamXL Kossel lengths will be put online once we are out of stock for the OpenBeam black (100696, 100674) and clear anodised (101563, 101552).

Products (almost) out of stock

Several products are (almost) out of stock: MakerBeam black anodised kits, MakerBeamXL black anodised kits, 600mm black anodised, 300mm black anodised etc.
Therefore we are also (almost) out of stock for our kits. Black anodised beams (MakerBeamXL or MakerBeam) have lowest stock levels.

We are expecting a new batch of beams coming in this July.  Around July 20th 2017 we will be fully stocked again.

You might want to check our resellers for their stock levels if you want a particular item that is out of stock in our webshop. Here is the link: Country list – Where to buy

On our bargain rack – buy four packs with 25% discount

We still have some old beams and these are now on sale for a bargain price. Already at 50% discount now there is an added 25% volume discount when you buy four while stock lasts.

Here is a link to our webshop SALE-page.

01bakitreg 4 - closeup bolt nut and black anodised makerbeamThese old beams are not hollow core and are not threaded. Otherwise these beams are the same: measurements (10x10mm) and anodised in both black and clear.

This volume discount also applies to screws with a serrated head. In our quest for the perfect screw for MakerBeam we also made screws with a head that has a serrated bottom. We ultimately chose to go with the square headed screws we still sell nowadays. Here is a link to an old blog post: MakerBeam’s test of the bolts

And last but not least we also have 900mm MakerBeam lengths in clear for sale. The thread tapping of this batch of 900mm beams was done in such a way that we cannot guarantee good quality. Therefore we offer these 900mm lengths at a discount.

New blog and Facebook

We changed to a new webshop. The blog featured on our website will have all the latest news. This blog will be updated with customer projects and other news items.

For all the updates please visit our website and look under ‘Blog & News‘ or check our Facebook account. You can also find us on Twitter @makerbeam.

Looking forward to keep you updated and communicate with you through these channels.

Team MakerBeam

p.s. This blog was edited on August 12th, 2016. We expected we could no longer make use of it after we stopped using our old website. No updates were posted. Since it is still circulating we reconsidered and started updating again.

Possible solution for Storage Box

We found a possible “candidate” for the new storage box. It tested good. According to our experience it’s a really good quality plastic box with lots of useful features: e.g.: click-on lid locking system, 2 levels for storing… Ideal for storing and separating the smaller pieces, and has spacious place for even the 300 mm beams. Here are some photos to give a little hint how it looks and how the MakerBeam / OpenBeam items fit in it. We still search a bit further, but maybe you will meet with this one in our product range.

MakerBeam Storage Box – sold out

Because of the terminated production the MakerBeam Storage Box is not available at the moment. We are searching for new solutions/sources, that we can offer instead, and we let you know if the new box is available.

The more possible sources we have, the more suitable solution we can find. So, if anyone has an idea or contact for sources of plastic box that is ideal storage place for different sized beams, nuts, bolts brickets and other accessories, please share it with us.  Thanks in advance!

 

Business and pleasure: Hannover MakerFaire

For us the MakerFaire started with this picture online, see below.

We were preparing a family visit to the Hannover MakerFaire.

MakerBeam was represented at the MakerFaire in Hannover by Chartup.
Thank you Anton!!

Saturday July 5th Johan travelled to Hannover to visit the Hannover MakerFaire. Since MakerFaires are fun for the whole family I followed later with our boys.
On Saturday he would focus on business. Sunday was scheduled for the pleasure part.

Preparing the business part.

Some impressions of the pleasure part.

Chartup with MakerBeam and OpenBeam in Hannover.

Elsie was a big attraction!

We had a great trip and wonderful days. Loved it!

Review – Corner Cubes

Introduction
Everyone of you who already used MakerBeam knows how difficult or rather time consuming it is to construct a corner out of three beams. Beside that, it costs a lot. You need up to three L-Shaped brackets, 12 bolts and 12 nuts. A new product solves this issue. It is a so called ‘Corner Cube’: a single piece of aluminum and three screws.

The biggest advantage of this new product might be that you can finally construct cubic corners. With the old method, using the L-Shaped brackets, you could not construct a cube as one beam was always “sinked” into the other. The new Corner Cubes connect the beams at their faces and therefore it becomes possible to create cubes as shown in this picture below.

Stability
Let’s start with the most obvious factor, stability. So far, we have all been used to the flat brackets which are screwed onto the beams with two screws per beam. The resulting joint provides a very stiff connection, see left picture below. It is obvious that the Corner Cubes will not provide the same joint strength due to their different design. However, our tests showed that this will not be of any issue for most applications. If required, the connections can be reinforced using the 90° corner brackets as shown below to the right.

 


Precision

This point is probably not that obvious at first, but after some thinking it becomes clear that the precision of the cubes themselves and especially the tolerances across different cubes matter a lot.
We have taken some measurements and the results were quite satisfying. From 12 cubes, we’ve found none that had difference from side to side larger than 0.1mm. A comparison between the dimensions of the 12 cubes lead to the same result: they are all equal to each another within a tolerance of 0.1mm.

Compatibility
The Corner Cubes only work on the new MakerBeams which have a threaded hole at each end. Therefore they can not be used with your current set of MakerBeams unless you have the tools to make a hole and wire tap the ends yourself.

This is also a limiting fact when it comes to custom sized beams. As the threaded center hole at the end of each side is not continuous, you also have to bore a new center hole and cut a thread yourself. However, only few people might have the tools and the knowledge to do this. Good thing that you can still use the old method!

Costs
Finally, let’s take a more detailed look at the costs. As mentioned earlier, you need quite a lot more pieces to build the traditional corner.

COST COMPARISON CORNER BUILD
Corner Cubes 90º L-brackets
Piece Price Quantity Total Piece Price Quantity Total
Cube 1,06 1 1,06 L-Bracket 0,65 3 1,95
Bolts Included Bolt 0,06 12 0,72
Nuts Not needed Nut 0,03 12 0,36
TOTAL 1,06 TOTAL 3,03

A traditional corner costs you €3,03. Compared to the €1,06 you have to pay for a ‘Corner Cube’ corner, that is quite a lot! Note: You can use just two 90° brackets to create a corner but then not each beam will be connected to both others.

Conclusion
The Corner Cubes do not only make it possible to create cubic corners, they are also about three times cheaper. Should you already own the new MakerBeam with the threaded hole at the ends, the Corner Cubes only drawback are the lower stability compared to the traditional method. However, it is possible to use the 90° corner brackets to reinforce the construction.
