Basic Hole Test Block

cults3d

While fine-tuning my latest design (set to debut soon in a repository near you), I discovered I needed precise information about how snugly my printer's holes were aligned. After all, when inserting a 3mm rod into a hole, maximum tightness is desired without causing any irreversible damage, right? To that end, I created this fundamental test block in FreeCAD which operates similarly to camera bracketing (remember real cameras?) - the baseline is centered with deviations on either side. In this instance, 3mm was accompanied by 2.8, 2.9, 3.1 and 3.2mm on both sides. As printers have varying tolerances in the XY and Z axes, this model allows you to insert it into both holes. If your shaft is larger than mine, you can easily modify this simply by adjusting the dimension specified in the "customize" sketch. Once the model has been recalculated, the offsets will be automatically calculated as well. However, you will need to manually change the numbers in the Body>Pocket001-numbers>ShapeString object data - but that's no major issue.
