Case for Beta65x and Beta75x with space for 8 Hobbyking Nanotech 300mah 45C 2S batteries. Included is Fusion360 file if tweaks need to be made and most everything is defined as parameters that can easily be changed. There are two versions of each. One loose, one tight. The loose fits a little too loose and in order to try and fix it given how long it takes to print, added some hot glue to the inside of the lid and squished it flat with my finger while it was still hot. This was enough to give it a nice snug fit. It's actually nice and smooth this way so I'm posting it as an option. I've also included tighter versions. Currently only printed the 65x loose version and in process of printing the 75x tight version. Update 1: 75x base right printed and fit is perfect (added picture). Tight top printing now and will verify the gap tonight. Update 2: Tight models are not tight enough. I thought a .2mm gap would be snug, but it isn't (loose is .4) so. A dab of hot glue in the corners that's squished flat while hot make the top nice and snug, but that wasn't what I was going for with the "tight" versions. Other than that, the fit is good. I'll update the models and upload again, but won't have a test print done until tomorrow. Note: current models are not updated yet. If want to do it yourself, can edit F3D file in Fusion360 yourself. In custom parameters tab, change the gap to .5 (gap measurement is for each side, so current value of .1 means a .2mm gap total) Other than that though, everything seems to fit well. Update 3 (final): .1mm total gap seems to be the right gap for a snug fit, so I've updated that and re-uploaded all the models. Loose is now .2mm total gap if want to try the hot glue method. It's a lot smoother, but to be honest, don't know how durable it will be. I mean you can always add more hot glue.. time will tell. Also, updated F3D file. The embossed text is the "text" sketch and 1.5mm extrusion into the top is the last step in the timeline which I've disabled, so if want custom text you can just edit the sketch and enable the last feature in the history. Update 4: 75x Tight top was corrupted, so I've re-exported and updated the file. Update 5: added versions for larger Tattu batteries. Don't have these batteries so no way to test, suggest print the Tattu battery test part to see if it's the right size before printing the case. If works or doesn't, please add a comment. Update 6: added 85x case for 4s batteries per request. Don't have one so going off commented measurements. If there's no confirmation yet, print the battery test square first. Update 7: 85x case confirmed working.
