TI 84 Plus CE and TI 83 Premium CE Calculator Slide Covers by Jimbotron

Last crawled date: 3 years ago

Update: 8/11/2018 - The "replica" 84CE/83CE slide cover has some aggressive curves that make printing without supports tricky. So I tweaked the fillet on the design a bit to make it print beautifully, with only a subtle difference from the original.
Update: 4/11/2018 - I've added a new slide cover that is very close to the original.
This is a set of slide covers for the new TI 84 Plus CE and TI 83 Premium CE graphing calculators from Texas Instruments. Now you can add some color to your Calculator, replace a missing slide cover, or add a little extra functionality to your slide cover.
If you just want a simple lid that is easy to print - pick option 1 below.
I have posted four options:
This is close to a replica of the 84CE and 83CE cover but with some tweaks for no-support printing. Use: "SlideCoverEasierPrint_84CE_Replica05.STL"
For a slide cover that very closely matches the original use but may need supports for optimal printing: "SlideCover_84CE_Closest_to_original_cover01.STL"
For a nice flat print-bed face use: "84CECoverRounded04_cleaned.stl"
Or the "84CECoverSquareandRulers11_nopads.stl" for a few extra features on the cover including:
An Inch Ruler up to 7"
A Centimeter Ruler up to 16cm
A Straight Edge for drawing lines.
A quarter compass for measuring angles.
A square edge to measure right angles.

Printing Suggestions:
This prints perfectly fine at .2 layers and 20% infill. However, for maximum durability and smoothness, I suggest 100% infill on a glass bed.
