Lulzbot TAZ Top Spool Holder

thingiverse

I wanted a spool holder that mounted on the top of my TAZ 4 without hardware of any type, so I threw this together. It's more solid than it needs to be, but it snaps into place on the 20mm extrusions and works beautifully. Uses a 3/4" dowel that just drops in. I'd like to integrate some 608ZZ bearings, but a) I was itching to get this made and didn't have any on hand, and b) I'm concerned that the lack of friction will facilitate spool unraveling - probably not worth worrying about. Instructions I printed it out of PLA with support, then measured and cut a piece of 3/4" diameter oak dowel for the shaft. I think it was 120mm, but measure the required distance before you cut. Let me know if you have any ideas for improvements!
