Lightly spray an even coat on one side of the print and then on the back side of the print. At this point it is important to make sure that the magnifying glass is already placed on the core, otherwise this will be a futile effort. The main reason for this is that I needed the PLA to be printed on top of the T-Glase as the other way around wouldn’t work due to the terrible adhesion when printing T-Glase on top of PLA. I used Simplify 3D to generate the G-Code and this is the resulting preview: Even though the print worked, it was certainly not an easy print. Since Simplify3D doesn’t provide a way to generate different parts of the brim with different materials and the adhesion between T-Glase and PLA is far from perfect, the prime pillar decided to make a run for it, resulting in a mess of spaghetti T-Glase. This is great! Once dried, begin to spray enamel coats again until the surface is smooth. You might like to use this printable magnifying glass template for your invitations and party decorations. The third design worked pretty well on every aspect: the size was just right, the LEDs and the magnifying glass fit really well, the connection between the LEDs was relatively easy to make and the diffuser (which was completely empty) worked pretty well. Unfortunately, at this point I came to the conclusion that white PLA for the diffuser was not the best idea as, even though it diffused pretty well. To do this, I stripped a cable and introduced it through each groove, finally soldering it to the anode or cathode respectively. Step #1: Prep the 3D lens file. Commercial License Included. Fortunately, this madness was contained to the last two layers containing T-Glase. Reply ! Next Prev. You can do this by swashing your print in alcohol.

Zip-archive contains jpg and eps files. 61 3D Magnifying glass models available for download. I also figured that connecting all of the LEDs in this approach would not be easy, as I would’ve had to squish the cables around the screws. A magnifying glass is a convex lens that provides a magnified image. Due to the parallel arrangement, each LED has the same voltage but, in very simple terms, the current is shared amongst them. The following diagram is a simplification of the final circuit using only two LEDs: Now the important part in this circuit is to get the current limiting resistor value right, otherwise we will either risk reducing the lifetime of our LEDs or simply not have enough brightness. I guess the next test is to leave a coated piece in direct sunlight for a few hours and see what happens. The smoother this first surface the better quality your 3D print will be as this is the foundation of your entire print.

In any case, I believe that white PLA with a hollow diffuser would have been good enough with sufficiently bright LEDs, so if you try it out yourself, let me know! Always keep the can moving and never over spray. Due to slight differences in the LEDs, one may take more current than the other, and can get destroyed (or at least will be non-uniform brightness). patricia beall. If you’re like me and you haven’t yet mutated a third hand, you will probably find it useful to have some sort of alligator clips stand to facilitate soldering or tinkering. You can see the scars on the bottom and back.

Did you make this project?  For the power supply I will be using a μUSB breakout board, since I always have a couple of cables lying around the table. The calculation is rather simple, but before we can actually calculate anything we need to find out the following: With all this information, it’s now easy enough to calculate the resistor value we need with the following formula: If you’re too lazy to launch the calculator app on your phone or on your computer, you can always use this online calculator, and go to the parallel case. The end result should look as follows: The final and probably the most exciting step of the process is to connect the arm back to the pana-hand and connect the μUSB cable. If you used similar materials you should get a pretty decent light diffusion all the way to the centre of magnifying glass. It is my hope that someone will read this some day and learn something so in this section I will go over the pretty basic electronics, the CAD model design and the selection of 3D printing materials. If you’re not interested in the process I followed to reach the final product, you can go directly to the build section. In my opinion Simplify3D is probably one of the best slicers out there, but I believe it still needs some work in order to support this type of prints. I could probably come up with a number of additions which would have helped, but the most important one I think would be the ability to print a brim on either the ooze shield or the prime pillar using the extruder assigned to each specific feature. Old one broke, some quick OpenSCAD, a screw and as good as new. 70º heated bed temperature with kapton tape. I will probably 3D print a different case since mine suffered damage during shipping.
