Collapsible Laptop Riser

Instructions

I recommend you position your parts in your board as did I in one of the images. Also, it makes sense to (in this order) apply tape, scan, position the parts digitally on Origin, apply additional tape to the areas on Part A (Slotted Board, leftmost on said photo) that won't be cut and then using "add to scan" to add the new tape. Why? a) By positioning the parts like I did, you'll be able to first cut out the two Safety Pins (Part D), then check if they fit into the slot inside the Stand (Part C) before cutting it out, then check if the Stand fits into the Slot in Part A before cutting that out. b) The most critical elements of this build are the 6 slots in the Slotted Board (Part A). Their size (more precisely: their height) will determine the angle of the Laptop Tray (Part B) when everything is assembled. Therefore, we want to be able to gradually enlarge them later on, even when the Slotted Board is already cut out. By using enough tape here from the start, Origin will recognize the Slotted Board later on and you can simply apply an offset to its slots, in contrast to having to fixture, tape, scan and grid again. As mentioned, start by cutting out the two Safety Pins (Part D). You can use a roughing cutter (e.g. 8mm) and an offset (0.8mm) for speed on the first passes (3.3mm, 6.6mm, 10mm) and the 6mm end mill for a cleaner edge on the last pass (12mm, 0 offset). Next, cut the slot in the Stand (Part C) with a slight offset (0.3mm) and gradually enlarge it until one of the Safety Pins fits in tightly. Cut the Stand out entirely. Afterwards, cut the smaller slot in the Slotted Board (Part A) with an offset and adjust it so that the Stand can slide in with gentle force. Cut the 6 critical slots for the Laptop Tray to offset 0 for now. Cut out the Slotted Board. Grab your second sheet of wood, tape, scan, and start cutting the Laptop Tray (Part B). The jet plane design also serves as a set of cooling slots for the laptop fans. It's meant to be cut using the 6mm and the 3mm bit. After you've cut all the parts out, it's time for an assembly tests. You can adjust the angle of the Laptop Tray by enlarging the 6 Slots (as described above) or using a file/sandpaper/sander. When you're happy with the angle, peel off the Shaper Tape (congratulations, you've reached the point of no return ;). If desired, round the upper edge (outline) of the Laptop Tray with a conventional router + roundover bit for a more ergonomic look and feel. Sand the parts and apply some protective coating (oil/wax/...). Gift it to a coworker or enjoy your new desk height yourself. Have fun :)
