Update - Printed, tested, and have fixed the bar ends, and re-uploaded a version that should press fit a bit more easily. Also closed the gap in the base clip to make it fit more tightly - uploaded new part. Update - Busted a base clip today, uploaded an improved part. Another quickie for you all: spool holder for a Prusa Mendel I3 Designed to take 10mm threaded rods, and two 608z bearings. If I have measured and compensated well, all this should just press-fit together and stay that way. we shall see later tonight All I had laying around was 10mm all thread, left over from my i2 and i3 construction, so I decided to make a spool holder to fit the left over bits. You will need to print 2 duplicates of each part. I suggest 100% fill, and get your host software to add a raft and support material. I'll post assembly pictures when complete, as currently this is untested. and all my machines are running flat out. enjoy - and comment if you need assistance.
