Samll familair knurled box
Posted: Thu Jun 21, 2018 9:17 pm
Folks,
As a newbie to Rhino 5 (Mac) and happy new owner of a M3-ID I've recreated the little threaded-lid box that came with the printer. Well, almost-- left off their logo, and made two versions-- first one with male threads on the cap like they sent, and the more standard 'box' version with the male thread on the container side. I've zipped the Rhino file of the latter plus the base and cap stl files, added them to my Dropbox account here: https://www.dropbox.com/s/469ydfq1k046y ... s.zip?dl=0
Note that the Makergear knurl pattern appears to use something like a polar array of 26, 60 degree V 'threads,' both right and left hand, both as a Boolean difference from the base 50x30 mm cylinder. I did that for my initial version, then went with a slightly coarser pattern. I've added about 0.12 mm or so of total thread clearance, which in hindsight might be a tad skimpy. In any case, when printed in PLA (no supports needed) a small 3M rotary bristle brush in 80 grit cleans things up nicely/quickly for a smooth action.
Fun learning project, however imperfect. Next up, when I get a moment, is to add a second color embedded butterfly to the lid. Rhino model is done, just haven't had time to print.
