Serious Clamp It Square ! (3 sizes)

thingiverse

If you build things, squares are a must have tool. What if, instead of checking if your works is dead square, clamping 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 will be useful in various kind 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, expecialy 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 preferabily 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 overtighted if the part have a low rate infill. My large Clamp It Square are made out PLA, 100% inflill with no issue. My advice, don't be cheap with infill : think life time tool. Edit : the Clamp It Square Mini size will probably don't need to stand high pressure. Otherhand, stick to at last 50% infill to be sure it stays in shape. Post-Printing Prevent work pieces marking ! Depending of your printer's accuracy, you may print artefacts and sharp corners. Look forward any print problem on the sides which 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. Actualy the Clamp It Squares uses less material possible and allows 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 to secure a corner between two squares, with a single clamp. That clam won't need a huge amount of pressure, so I limited it to 28m (more than 1"). See below an exemple of clamping process. Believe me, that parts are not going anywhere. Mini size added ! The Clamp It Square Mini is for smallest jobs It's expecialy designed for spring clamps.
