![]() Somewhere I saw a flexing rod support on a printer bed and thought that was just the idea for my application. Opening up the narrower side proved to be a lot more fiddle and really got me nowhere. I tried squishing the frame sides together at the wider point, but that only brought the ends in by 0.3mm out of the original 0.65mm difference. In fact I got it down to about 0.045mm which was nowhere the tolerance needed for a SCS10UU bearing at 0,015mm. Some pondering had me wondering if the 2 rods were parallel and so I made a quick tool to check.Ī length of M6 threaded rod will have 1mm of travel for 1 rotation, the nut has 6 flats and 6 points, so that will yield a resolution of about 0.08mm per mark. The entire build from assembling the precut frame pieces to first print was 40 days.ĭue to my particular custom build, I bought 2 x 1m long hard chromed tempered steel rods and cut them to fit, using the 2 x 320mm lengths here and 340mm on the X and Z axes.Ĭommercial rod holders are 40mm in length and I thought I could better that with a diy version and save some travel on the Z axis. I decided to source all parts locally in South Africa due to the 2 month shipping times from most international suppliers like Banggood etc. I work in a randomly impulsive organic way and so I'd first built the enclosure for an ordered and paid for Anet A6(Prusa i3 clone), but that never materialized, so I was stuck with a 500mm x 400mm x 400mm perspex enclosure and a pocket full of refund. Not forgetting the ubiquitous dremel which did all the little handy things that dremels do. I have a benchtop mill and so that was used to face a lot of the pieces square in the critical areas like the Y guide rod brackets and the X/Y joiners.Īnother specialized tool was the 10ton hydraulic press from a previous instructable that was used to bend the 12mm thick aluminium for the idle pulley brackets. ![]() My main tools were the hacksaw and 2 files, a rough and a 2nd cut, a digital caliper for all the measuring and marking, and the benchtop drill press for a lot of the drilling. I went with 6 SCS10UU linear bearings to make mounting my aluminium meccano pieces easier. ![]() I used mainly, 1 metre of 25mm X 12.7mm aluminium bar and 1.8m of 3mm thick 25mm equal angle for the various parts.
