UFS-091 Radius Gage Starrett Style - New Year Challenge by UncleFrankSays

Last crawled date: 3 years, 5 months ago

I’ve seen several radius gage sets on Thingiverse. Some were clever, some were dull, but none compare to the design by Starrett, No. S167C. This is a set of fractional inch radius gages. I’ve used a set of these for years to measure small curved parts. Each gage has five (5) different ways to check a radius. There are half and corner radius checks, both inside and outside. They are the best. In fact, nothing you can 3D print will equal the quality of this set. You should just go buy a set if you really need to check a radius accurately.
Sometimes you have to make do with what you have. If you don’t have a set of radius gages made by Starrett, but you do have a 3D printer, then maybe these will be good enough until you can get a better set.
30-Day Challenge to Everyone
Because I spent hours on designing this set, I have a series of challenges to any who are interested in downloading this set.
Why?
I know that most people (including myself) will download a project and post nothing, give no positive feedback, and show no makes of their build. For those of us who make designs, there is little incentive to post the next great idea. I decided to have some fun with this project and see if we can change people’s attitudes.
Step 1. I am going to release eight of the smallest sizes, 1/32” to 9/64”.
Step 2. Users will have to add a minimum of 10 comments. These have to be from 10 different users, and each comment must be different. Any feedback should be positive. I don’t need compliments, but why should I release more gage sizes if you leave negative comments. If we reach this goal, I will release eight more sizes 5/32” to 17/64”.
Step 3. Now we need to get serious. One of the few things that Thingiverse values is “likes”. This is how "popular" on Thingiverse is calculated. This project needs to get 100 likes. With this goal we will release four of the larger size gages 9/32” – 3/8”.
Step 4. The project must reach 300 likes. With this goal we will release the final four of the larger size gages 11/32” – 1/2”.
Step 5. ??? To be determined.
How to print
The parts are designed to be 1.2 mm thick. If you are printing at .2mm height, then there are six layer total or 3 layers bottom and 3 layers top.
Normally I avoid using a raft, but for this design avoiding elephant foot is a must.
If you can print out a template to scale. There is a reference block on the template that is 2” x 2”. Shrink or stretch the print to get the block to the correct size. Now you can compare your 3D printed parts to the 2D template. Sand as needed.
