Basic Hole Test Block

thingiverse

While working on my latest design (coming soon to a repository near you), I discovered the need to know just how tight my printer's holes were. When trying to force a 3mm rod into a hole, it's essential to have it as tight as possible without causing any permanent damage, right? To that end, I created this basic little test block in FreeCAD that functions like bracketing on a camera (remember real cameras?) where you have the base line in the center and deviations on either side. In this case, 3mm with 2.8, 2.9, 3.1, and 3.2mm on either side. Since printers have different tolerances in the XY and Z axes, this model lets you put it in both holes. If your shaft is larger than mine, you can easily modify this by changing the dimension specified in the "customize" sketch. Once the model is recomputed, the offsets are automatically calculated. You'll have to modify the numbers manually in the Body>Pocket001-numbers>ShapeString object data, but that's no big deal. --- **Reminder** * Due to either a Thingiverse bug or (more likely) shadowbanning, my models no longer appear under the [Newest] listings. If you want to see more of my models, please be sure to follow me. **If you print this, it would really help if you'd post a 'make' so that others could find this model**.
