Thanks, Lee! I appreciate the expert insight. I hope Steve is able to rejigger the hook tabs with slightly less overhang.
$15 for 50¢ of material sounds crazy, but I don't have a 3-D printer. Are there any 3-D print services that aren't so expensive? My local makerspaces have closed their doors to focus on PPE right now. —b9 Lee Olivares <l...@braains.net> wrote: > The “vertical” hook tabs are on the weak side, simply by nature of their > geometry and the limits of FDM, but they’re certainly functional. > Unfortunately re-orientation of the model isn’t a great option to improve > their strength, nor is beefing them up, simply because of the size of the > slits in the case. > > However, making them with slightly less overhang would prevent some harmful > leverage without affecting function, and it would permit “scooping” the three > engagements on the short side, since the tolerances there are pretty tight as > it stands. > > Managed to fracture one of the vertical “hook” tabs removing the support, and > it’s a snug fit but a really great design. > > Thanks! > > > > - Lee > - 909.437.0250 > - Destroying technology problems. > > > On Jun 28, 2020, at 21:39, Lee Olivares <l...@braains.net> wrote: > > > > Resident 3D Printer repair guy here: that’s expensive, you’re looking at > > .50c in material for an FDM PET print. > > > > It’s about an hour on a Prusa MK3S @ .2mm, I’m fairly certain my buddy > > gifted me an M200 so maybe I can do some comparison shots. > > > > Printer is hot and ready so I’ll just crank out a sample as a reference, > > wait 2hrs before making any purchases. > > > > - Lee > > - 909.437.0250 > > - Destroying technology problems. > > > >>> On Jun 28, 2020, at 20:04, B 9 <hacke...@gmail.com> wrote: > >>> > >> > >> Very awesome!
