3D Files

Postby bdring » Fri Nov 12, 2010 1:22 pm

I have not figured out a good way to share the 3D files efficiently. They change so often I would spend more time maintaining the on line versions than doing design work. I can probably provide STEP file snapshots of the design via email by special request to active forum members.

I don't use those clamps on the design anymore. With practice, acrylic is easy to tap. Unfortunately, many people had nothing to practice on and broke a part or two. These tiny clamps were especially vulnerable. I switched to this style. The belt is tensioned by moving the idler pulley.

I have attached the clamp drawing in case you want to use it anyway. It is a PDF with a DXF as an attachment.

Great thank you ~ I won't be tapping the hole just making a square cutout for a nut to fit into and drilling all the way through, if it works will post the drawing here Reprap WIKI and Thingyverse. It will be for the 5mm pitch 1.2mm thick Syncroflex belt as it not so easy to get the 80thou belt here in the UK.

I may also try out 2mm pitch ball chain as a drive system ~ though im not sure that the 2mm pitch size is universaly avalible.

There are alredy a few designs using the 3.3mm and 3.5mm diameter ball-chain on Thingyverse for Reprap type machines.

I found out the nozzles I had on order probably won't come in until the first week of January. Sorry for the delay for all who have requested them.
