Harbor Frieght Screwdriver Tray

I was at Wall Mart when I saw an inexpensive Mini screwdriver kit with multiple tips. I resisted the urge to buy it after I realized I had a similar one from Harbor Frieght. I just hated the fact that the tips were loose and would fall out easily, whereas the one in the Wal Mart kid was more secure and attractive. So I went home, sat down, and came up with a design to hold all the bits and the holder.

Overall, it's just okay. The screwdriver itself doesn't fully fit in despite the bottom plate being thin. I guess the original plastic holder was even thinner. So this means that the case doesn't stay fully shut. Still, I keep it in a small nest of closed drawers so it won't open up by mistake.

I made this in Happy 3D that came with my FlashForge Dreamer NXC printer, as i haven't sat down to leave AutoDesk Fusion 360 or higher-end programs yet. I started by making a test with the small holders until I (thought I) perfected the distance. When I printed it out at 100% they were too loose and the entire plate didn't fully fit. When I put it in the slicer I scaled it down to 70% and while it fit, the bits were to difficult to remove, and doing so resulted in broken plastic. This last one I scaled down to 98% of the original, which is what the file is, and the bits are held in nicely without a lot of resistance. I wasn't sure of a proper way to hold the screwdriver which is why I put two cylinders to hold the middle and a third one at the bottom just in case. A standard speed print with a raft should take about 4 hours and 30 minutes. Because of the flexibility of getting the bits out I used flexible filament, which has a color that retro-contrasts against the blue case.
