Serious Clamp It Square ! (3 sizes)

thingiverse

If you build things, squares are a must-have tool. What if, instead of checking if your work is dead square, you clamp it directly to a square for a good result - first time, any time? You can't always find Clamp It Squares in your local store. Especially in Europe. And if you finally find some, serious models will cost you about 10 bucks each! The Clamp It Squares I designed are actually available in three sizes: Large, Midi, and Mini. They'll be useful in various kinds of jobs, from light DIY jobs to serious furniture making. One last advice: don't over-tight the clamps, as the job is well done, no joinery needs extra pressure. Edit: Added a new size - the Clamp It Square Mini, for smallest jobs, especially designed for spring clamps. Edit: If you're looking for holders for your clamping squares, I recommend Gromax's holder for midi size: https://www.thingiverse.com/thing:3135812 Edit: added a beefy version of the Clamp It Square mini, by onlytobeking. Print Settings Printer Brand: RepRap Printer: Prusa I3 Rafts: No Supports: No Resolution: Does not matter Infill: 50-100% with warnings Notes: Use preferably strong and stiff material, like ABS, PETG or PC. Don't use flexible filaments like Nylon ones, because you won't be able to maintain a trustable squareness. PLA is possible, but be aware PLA can explode without warnings when over-tightened if the part has a low rate infill. My large Clamp It Square are made out of PLA, 100% infill with no issue. My advice: don't be cheap with infill - think life time tool. Edit: The Clamp It Square Mini size will probably not need to stand high pressure. On the other hand, stick to at least 50% infill to be sure it stays in shape. Post-Printing Prevent work pieces marking! Depending on your printer's accuracy, you may print artefacts and sharp corners. Look for any print problems on the sides that can mark your clamped parts, and do a little deburring. How I Designed This Life time tool wanted! To me, a tool must be trustable - first time, any time. I did a bunch of prototypes to get the right shape. Actually, the Clamp It Squares use less material possible and allow any clamp shape to be used: I added a special feature. Someday you may want to apply extra pressure to the corner itself. Instead of needing another tool, I changed the shape to allow securing a corner between two squares with a single clamp. That clamp won't need a huge amount of pressure, so I limited it to 28mm (more than 1"). See below an example of clamping process. Believe me, that part is not going anywhere. Mini size added! The Clamp It Square Mini is for smallest jobs. It's especially designed for spring clamps.
