The Libra - A Filament Scale for the MasterSpool

thingiverse

February 10, 2020 - I also created a holder for the 2020 Profil on Thingiverse in case someone needs it. February 9, 2020 - Finally Done! The Final Version is 2cm Longer since it was all wobbly on the Holder and I thought the Spool would easily fall out of the side. So, I fixed that. I also moved the Text up a bit to align with the holes for the Bearings, which was more likely an Optical Thing I did. I also fixed a few minor Details inside the Base and added a little gap for the Cables of the HX711 on the side. What I didn't test yet is a little block to align the HX711 while screwing it on because it has to be centered right to work correctly. So, it's just a helping thing which can be easily cut away if not needed. February 1, 2020 - I finally printed it... Everything fits nicely as you can see on the Pictures. The only issue I found was that I somehow got confused and had a completely different number for the width of the Spool in mind than I should have used... So, I started over, reworked my fusion Design quite a bit, and made everything parametric because it really was a hassle to make the whole base slimmer without Parameters. As of right now, I'm printing Version 2 of the Libre. This time it's really for the MasterSpool! And for the V1... I think I will just release it as a Remix for Spools up to 10cm Width because well... The Design is done and it's still the same... Just with a larger base. January 26, 2020 - Currently printing it but since the sizes of my other Designs worked nice, I think this one will also succeed. So Pictures of it will come at a later Date... I really wanted a nice-looking Filament Spoolholder for my Ikea Lack Enclosure which has an integrated HX711 Scale inside but just couldn't find any which looked nice or had the right Dimensions for a MasterSpool, most of them were too small or just way too big (which of course wasn't written in the Description...). After some Time I found this one from the German Make Magazin on Github which looked really nice but had a few Design flaws like the Tare Button, the Display, and the whole Custom PCB Thing which really was all quite useless if someone wants to use it with the Octoprint Plugin or write some code himself (like I'm planning to do). And of course... The whole thing was done in SketchUp which I think really sucks if you want something Dimensional accurate. So, I redesigned the whole thing in Fusion 360 and made it my own. Anyway... The Libra Base is just the first piece of a Modular Design that I planned but since it's working on its own with the Octoprint Plugin I already released it.
