The hypotenuses of these triangles slide along number lines, while their vertices are connected, forming a hinged rhombus. By placing the sliding points on different integers, the calculator determines the midpoint of these integers to display the results. This model is based on <a target="_blank" href="https://patents.google.com/patent/US1188490A/en" rel="nofollow noopener">the expired “educated monkey” patent from 1915</a>.<figure class="image image_resized" style="width: 77.87%"><img src="https://makerworld.bblmw.com/makerworld/model/DSM00000000510362/design/2024-06-23_64af858aedd67.png"></figure><h2> </h2><h2>Assembly Guide</h2><h3>Froggy Version:</h3>Step 1: Place the Screws, Feet, and Vertical Bar onto the Base.<figure class="image image_resized" style="width: 70.46%"><img src="https://makerworld.bblmw.com/makerworld/model/DSM00000000510362/design/2024-06-23_fa5748c5a3b0a.png"></figure>Step 2: Add the Legs.

Here is the Michigan light box I made. I thought I had better pictures. But it did turn out great. there is a clear layer to hold the thin color layers together. I used Inland Natural. Im not sure if or how white would work. I also used Inland Yellow and Inland Dark Blue and Bambu Black.

Needs to be printed diagonally on most printers. You can just barely squeeze it in on a Bambu without rotation, can print 4 at a time if you really wanted to. Designed to match the height of an ikea alex top drawer with the basic gridfinity baseplate inserted.&nbsp;Larger bins like this do like to warp but I've printed a bunch now with my Bambu Printers and haven't had any real warping using the two profiles I've uploaded. I prefer the angled one as it keeps the PTFE tube and print head from making excessive noise.&nbsp;I'm working on a bringing the print time down in a version 4!

A simple solution to solving the filament spool drag on the rear spool holder. Great for printing with TPU or cardboard spools as this reduces the strain on the extruder.&nbsp;UPDATE: I have tweaked the model dimensions of the roller to allow for some more tolerance with different spool holders. Some people reported it not fitting. These have been added as v2 parts. The originals are still there for people who liked the tighter fit.&nbsp;3 parts to print:<ol><li>Thin spacer which inverts the keying of the rear spool holder allowing you to bolt it in upside down. Uses exactly the same bolts as are currently fitted, no need to find extras.</li><li>The cradle which rests in the now upside down spool holder.</li><li>The spindle which is designed to combine with 2x standard 608 bearings and then rests in the cradle.</li></ol>Extra parts needed:2x 608 bearings (22x7mm w 8mm hole)&nbsp;It's been designed so the spindle is a few mm smaller than the bearings which provide a stop point so your filament roll won't make a run for it. Due to the space the bearings take up, it will only fit spools up to 72mm in width.
