Sonic Screwdriver For My Wife

thingiverse

This started out as a simple Laser pointer for my wife, but since I couldn't leave well enough alone, it has turned into much more. First off, I need to give credit to TheDoctorsApprentice for the inspiration with https://www.thingiverse.com/thing:1232280 and Honus for his screwdriver at http://www.instructables.com/id/DIY-functional-Sonic-Screwdriver/. They both gave me the crazy idea that I could do this. It has taken me three months and many different redesigns to get it to this point. Now, I have to say yes, it is similar to River Song's Screwdriver, but it is not exact. All I had to go by is pictures on the internet, and we all know how accurate they are. The scale is off a bit, making this one larger, but I made it beefy to allow usage as an everyday tool, laser pointer. I also had to make room for the items inside the unit. Look back at the cross section; you will see three red switches that are robbed from the control panel of a printer. They activate the LEDs and the laser pointer and the piezo speaker. I used a LIPO Charger in the front under the top cover at an angle to recharge it. I used an Arduino nano for my layout, which is the green board shown, but I will be using a Mini Pro for the actual brain. The battery is a 3.7v 500mah battery, shown in purple in the cross section. I have it set up to use the front button for the Sonic Screwdriver activation. The lower rings when compressed will activate the laser pointer, and then the rear button activates the rear flashlight. I was able to hide the front and laser buttons in the unit, but came to the conclusion that fumbling around in the dark would be easier to have the flashlight button easy to find out on top. I am using Bronze PLA for all the yellow objects, Black PLA where they are black, Silver is Aluminum PLA, and I used clear PLA for the front nose piece and the lower light bar. Both are lit up with blue LEDs. I made the handle out of wood-impregnated PLA so that I could stain it later on. I couldn't figure out the handle texture of the original or say how to design it with the texture, so that is where this one started to deviate and went downhill from there. Why all PLA? Well, my homemade printer has a lot of trouble printing ABS, so I went with what I could. The green thing in front of the battery is the piezo speaker, and the second rear ring has holes in it that will align with the holes in the first rear sleeve. This is my attempt at a volume control for the speaker. The first rear ring has an odd lump off the side of it; that's used to keep the lower rings from being compressed in a handbag or something, and the laser pointer being lit up. I am taking a chance that the rear flashlight button doesn't get compressed and draining the battery... I will just have to see. The top cover is hinged with a 2mm rod I had laying around; something I pulled from a printer at one point. I found with my printer, the hole printed smaller. I could've used ABS 1.75mm filament as a hinge by drilling the hole out a bit. I designed this to be assembled together with glue, some of the fitting is tight, but will work. At this point, I am finishing the prints of mine and will be working on the wiring shortly. So that's why I don't have pictures of mine finished and working. I am thinking of making a box to carry this in; what I have in mind is something that would look like a large sunglasses case. I hope this item doesn't get flamed too much. I have spent a while getting it to this point, and I have to say it's the most intricate thing I have ever attempted. I still want to add and change it, but I am heading back to the office now... Print Settings Printer: Home Made Rafts: Yes Supports: Yes Resolution: .1 Infill: Mostly 80% Notes: I tried to make each part easy to print and its orientation to the print bed with the least amount of supports. You will have to rotate them and look for curved chamfers that allow it to be printed with them facing down. The hardest item to print is the Front Handle Sleeve; that one had to have supports no matter what I did to it.
