+# Ferris Sweep v2 Case
 
+This is a remix of [Bubbleology's](https://www.printables.com/@Bubbleology) [Ferris Sweep v2 Case](https://www.printables.com/model/215167-ferris-sweep-v2-case). It is a combination of some of the model files which Bubbleology has made avaialble. Notably: 10mm bumpons, no PCB breakout recesses, and with a TRRS breakout.
+
+This remix includes the following changes:
+
+- Holes for attaching the PCB to this case have been widened to accept heat set threaded inserts. M2 x 5mm hardware is still used.
+- Thes holes now extend through the body of the case so that a threaded insert can be fully set.
+- The depth of the "floor" of the case has increased.
+
+## Printing
+
+I printed using PLA at the manufacturer's recommended temp of 220°.
+
+- 25% infill
+- 1.5 wall thickness
+- No supports
+- Bridge - probaby not necessary 🤷‍♂️
+- Mirror for right side
+
+## Hardware
+
+- 14 x 10mm rubber bumpers (3/8 inch)
+- 8 x M2 5mm bolts (6mm is probably ok but untested)
+- 8 x [M2 heat set threaded insert](https://www.amazon.com/dp/B0CS6XJSSL?ref=ppx_yo2ov_dt_b_fed_asin_title)
+- ~2mm thick foam
+
+## Assembly
+
+Place the printed case on something flat, sturdy, and heat resistant. Use a soldering iron to set threaded inserts into each hole, using little to no force to allow the brass insert to push all the way through and contact the work surface.
+
+Cut 2mm foam to same shape as PCB, then use 5mm hardware to attach PCB to case with the foam as a gasket.
+
+Refer to Bubbleology's original instrcutions for more details.
+
+### Pictures
+
+I haven't finished this build yet, but will add photos once it's done (along with any needed updates).
