MacBook vertical stand

Vertical stand for MacBook with holes for ventilation. I found giahuy2201 's model but I noticed that it was missing holes for ventilation. So I added holes on one side for better ventilation and hole design matching the entire piece. Printing When printed at 100% on all axis, the clearance on the slot is 18.26mm, so that is the maximum thickness of the laptop (again, at 100%). If another dimension is needed, bigger or smaller, the model can be scaled on one axis. I use it for a MacBook Pro 16'' 2019 that is 16.2mm and added two 1mm adhesive foam sheets, one for each side, that added to approximately 18.2mm so it has an almost tight fit. Scaling Method 1 (New, requires PrusaSlicer >2.6.0) Since the release of PrusaSlicer 2.6.0 alpha 2, a new tool is available, the Measurement tool, that allows us to scale the model very easily. With the model imported on the slicer, select it and select the icon for “measure” on the left. 📷 Image redacted — claim this model to add your own media Select both the left and right inside faces of the model 📷 Image redacted — claim this model to add your own media A good dimension for the laptop gap is (laptop thickness + tolerance x 2). Around 0.15mm tolerance should be good. With the math done, input the value and click “scale”. Method 2 (Old) Scaling can be a bit challenging using the Slicer since we only get the outer dimensions of the object, however, we can use Math to solve this issue first. Since we know the inner dimension at 100% is 18.26mm, we only need the thickness we desire. 📷 Image redacted — claim this model to add your own media Let's say we want to resize the piece to use on a laptop with 15mm and a press-fit (no space left), using the "rule of three": 📷 Image redacted — claim this model to add your own media Or we can use an online Rule of Three Calculator : 📷 Image redacted — claim this model to add your own media The outcome in this scenario is 82.15, but wait! ⚠ Don't forget to account for printer tolerances, quoting Mikolas Zuza in The Surprising Practical Uses of Color Change in PrusaSlicer , “ 0.15 millimetres in every direction should be enough.” So to the 15mm, we would add 2 times 0.15mm, giving the final dimension of 15.3, let's update the rule: 📷 Image redacted — claim this model to add your own media The adjusted outcome in this scenario is 83.79, so we would change the scale on one axis to the value of 83.79%: 📷 Image redacted — claim this model to add your own media Et voilà, we have the object sized according to our needs. Scaling TL;DR Find the dimension of your laptop (MacBook size list below). See if you want a tight fit or have some gap space between the laptop and the object. ⚠ Account for printer tolerances (usually 0.15mm is a good start, double it to account for both sides). Add it all and use the rule of three with the values we already know from the object, 100% represents 18.26mm, and X% should mean (laptop height + gap + tolerances)mm. Adjust the scale in the slicer on only one axis.
