The rest of our design aims would begin to emerge once the physical measurements of a resistor had been obtained. It also needed to be of sufficient length to be user-friendly. We tried to keep this firmly in mind through every step of the process. We wanted it to be easy to design and to also lend itself to being 3D printed without any issues. We wanted to produce a tool that allowed us to bend the leads of a resistor in a uniform way so that when they are placed on a PCB and soldered they all look the same, with the body of the resistor being centred between the holes. 4 - Using our 2D design to model our 3D object.3 - Creating a 2D design that delivers our design aims.How To export the design for 3D printing.How to turn a 2D design into a 3D model.We chose to use 123D Design by Autodesk for several reasons Schools can download it and use it for free, it has a much shallower learning curve than most commercial products and it is more than capable of the job in hand. An Introduction To 3D Design In 123D Design: They consolidated the tools and features of these Apps into key apps such as Tinkercad, Fusion 360, and ReCap Pro. NOTE: Since we published this article Autodesk have discontinued all 123D Apps & products. If you would like to print one right away you will find a link to the STL file at the foot of the article. The designs and the printing were done by someone who is new to both, which highlights how easy it is to produce something usable using the highlighted tools. The purpose of the design was to produce a resistor lead forming tool that would ensure that all resistors in a project were bent in an identical way, the perfect tool for those working on an electronics project that is going to be marked. Anyhow with regret, I am now going to try 123D Design and see if I like it any better.This is a step by step guide for using free design tools to create 2D and 3D designs for 3D printing and is intended as an introduction to 3D design. Maybe I am just a perfectionist / complainer. So in the end I had to find out the name of your link, search for that name from Window => Extension Warehouse => search for “Sketchup STL” (there are 400 results that come up but luckily it turns out to be the first of them - but I had to CHECK that fact…)ĭon’t get me wrong - I have received a lot of help from this community and I am extremely grateful… but that doesn’t stop me from finding Sketchup - between moments of sublime brilliance - DEEPLY frustrating! If I download the file and run using Sketchup it fails. Fine by why waste my time with OBJ if it has bugs (?) and is less widely used.Īlso irritating is trying to install the extension. Now it turns out that STL is probably better. And the only one that overlapped with his software was OBJ. They just asked what export formats can you do. Either way, nobody at the local hackspace told me about STL. If most people are using STL not OBJ, then why don’t we get STL as standard. So I now don’t really know WHICH version I was using when I did the export.Į.g. It took me a LONG time to work this out because the two version are not properly named with 2015 or 2016 in the title. However for some bizarre reason when I type “Sketchup” into Windows (8.1 圆4) Start Button search box the ONLY one the came up is the 2015 version. It turns out the I had both Sketchup 2015 AND Sketchup 2016 on my laptop computer. If you want the truth there are just too many things about Sketchup that cause me to cuss and swear "G*d I hate sketchup!)Į.g. I am a relatively slow learning and I value my own time, so choosing the best tools is important to get right… Can anyone tell me how 123D Design / 123D Make compares with Sketchup Make for 3D Printing?.If pushed I could possibly spend something on software ($100/year max) but I have very little money to spend on software so both being free (“freeware”?) is a distinct advantage. The my Sketchup model also contains some ‘structural’ errors (my bad) so I may as well re-build from scratch in any case. I have been advised by staff at my local hackspace that I would get better results using 123D Design /123D Make (from Autodesk) which like Sketchup Make is also free. However when I exported my model to OBJ format, ready for 3D printing (using MakerBot ?) it was clear that there were errors in my model, despite the fact that Sketchup accepted my model as being ‘solid’. My local hackspace/makerspace has some 3D printers. This is no doubt heresy, but I have been advised to use 123D Design (=> 123D Make) instead of Sketchup Make, as a result. The model that I exported into OBJ format (in order to 3D print it), contains errors.
