Multi Level Hex Bit Organizer with Misc Parts Tray

*** note - Please do not try to print this without reading the "Printing Instructions:, you could end up wasting a lot of filament. --- I couldn't quite find what I was looking for so I decided to model up my own version of a hex bit organizer. This design comes in multiple variations (3 level with tray, 2 level with tray, single level with tray, single level without). The key design features were: * holes are 7.5m point to point * holes are about 1.5mm apart * holes are offset to allow for more bits to be stored * miscellaneous parts tray to allow you to temporarily store your bits before returning them to their respective holes Printing instructions: 1) Do not attempt this unless you've calibrated your printer. The dimensions on the holes are such that if your flow rate is off, extruder not quite calibrated etc, the holes can end up printing too large or too narrow (mostly too narrow). 2) As a prerequisite, make sure you've done your e-step calibrations followed by flow rate calibration (Cura), and that wall widths on test cubes are printing out properly or within an acceptable range 3) To make it easier - I included a few test cubes so you can print off mockups of the holes to assist in calibration. The bits I use measure about 7.15mm point to point. The holes are designed to 7.5mm. On a stock printer with no calibrations, that printed out to about 6.85mm distance from point to point. 4) Once you've calibrated your printer - the key setting in Cura that will ensure your holes come out the right size is "Hole Horizontal Expansion" under the Walls menu. To get my test cubes to print out ~7.5mm I ended up with a setting of .07 for that HHE setting. Bit of trial and error - but a 12 minute print is better than a 14 hour print and only then discovering the defect. Standard PLA settings apply after that. I used 10% infill to save time but it only shaves about an hour off the total time. This is a work in progress...Let me know if you'd like anything added to the design.
