Available in any file format including FBX, OBJ, MAX, 3DS, C4D 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 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. Now its your turn to refine this and improve upon the process. Here’s the parts manifest: Helping hands or 60mm magnifying glass; 12 White LEDs Since I have a Form1+ from Formlabs I used Preform as the software to print this model. Helpful. If you’re still wondering about the result in this particular case, it’s 22.9Ω but the closest resistor I can buy is 27Ω. … ! After you spray if you see a bumpy surface you are either under spraying or you are spraying too far away from the surface (the enamel is semi dried and is loosely adhered to the surface). 33. As you can see on the following picture, the light diffusion is quite nice on clear T-Glase: Unfortunately, once I made the decision, I opened a small Pandora’s box of my own. The material choice I went for was Clear Taulman T-Glase. I use a Micro Soft Wire Cutter to remove supports. An illustration of a magnifying glass. 61 3D Magnifying glass models available for download. Or you can use your own design. The first attempt was a 10 Euro set of magnifying glasses that have different strength lenses that interchange for different amounts of magnification. The electronics of this project are very simple, it is just an LED circuit with 12 LEDs in parallel and a current limiting resistor in series with the supply. T-Glase is famous for being difficult to print with problems ranging from terrible overhangs, irregular extrusion, flimsy layer adhesion and, to make matters worse, T-Glase has very little adhesion to PLA, so the dual extrusion idea was going to be quite difficult. I've reduced the contact area as much as I can in my software, but still it is an issue. 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. 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).

A housing charity and a technology company teamed up to create what they say is "the first permitted, 3D-printed home in America." As mentioned before, I used blue PLA for the core and the lid, and Clear Taulman T-Glase for the diffuser. I must admit I was lazy enough to use this calculator, but in fairness it does provide you with the closest resistor to the value you can actually buy, which is pretty handy. Scale the lens in your CAD program, using calipers or the width dimension stamped on your old frames. You can use a magnifying glass to read small text or work on hobbies like model-building and knitting. Reply Read more. 4.0 out of 5 stars 6. 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 goal of this project was to see if it was possible to create a 3D printed magnifying glass with no sanding or polishing needed. In this post I will explain how to 3D print and build an illuminated magnifying glass for a Hobby Creek Pana-Hand. Lightly spray an even coat on one side of the print and then on the back side of the print. I used this setup to get the board in place and position some solder close enough so that I wouldn’t have to hold it, but unfortunately the transistor is really small and I had to use an external illuminated magnifying glass to actually be able to see anything. … Change ).

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. patricia beall. Dithermaster you are right about only using 1 resister being a bad idea, however the ideal solution is to use a current limiter with each led. To do this, I stripped a cable and introduced it through each groove, finally soldering it to the anode or cathode respectively. Fortunately for me, I’m not afraid of soldering so I decided to buy a bunch of transistors and go for the kill. Weighing 13 grams, you could crank out 153 of these 2 inch tall tops from a standard roll of PLA printer filament. on Introduction. You can see the scars on the bottom and back. In any case, it worked fine for me and if you break a couple of LEDs it’s not the end of the world.

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. Hang dry for about 8 - 12 hours after your last coat. This would not be as convenient to implement as powering from a USB cable. Once your 3D print is clean, go ahead and remove supports. 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.

With all the decisions made and the models generated, it was time to get on with the 3D print and the build of the illuminated magnifying glass. The motivation for this project came when I was building my new dual extruder 3D printer (which I used to 3D print the models I will later show) and somehow managed to short out the fan pins and burn an SMD MOSFET. I have had great success in removing uncured resin by using an ultrasonic cleaner filled with +90% isopropyl alcohol. And I usually have to sand my pieces after removing supports due to scarring from where the supports touched. * *Yes, yes, 3D printing uses the metric system and filament is measured by the grams and meters. I guess the next test is to leave a coated piece in direct sunlight for a few hours and see what happens. 3D printed magnifying glass fix for helping hands. I also glued the breakout board to the core with some cyanoacrylate: The next step was to connect the arm and the lid using the original screw, at this point I must warn you that the screw I received on my Universal Holder Arm might be different to the one you’re using, so it might not be a perfect fit. Allow the can to rest for another (3-5 mins). Press J to jump to the feed. I printed this model at .05mm layer height.

You might like to use this printable magnifying glass template for your invitations and party decorations. For example, 50-18-135 means 50mm lens width, 18mm distance between lenses (DBL), and 135mm temple length. One question, does that enamel protect from UV? So once I got past this particular bump on the road, I went ahead and created my next and final design, which included a solid diffuser and a much more compact lid, with the arm connection on the inside. The model itself had a couple of requirements such that it should fit the 60mm magnifying glass, the 12, 5mm LEDs and the μUSB breakout board. My original idea was to divide the model in three different parts: the light diffuser, the core and the lid. I started with a very simple prototype which was probably unnecessary and a product of impatience. You might like to use this printable magnifying glass template for your invitations and party decorations. The second prototype was another failed idea, but it allowed me to understand how to better design the diffuser since the small diffuser was not very effective. This will ensure your can is evenly mixed but not too agitated to introduce air bubbles on your print. 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.
