Zest - Foldable Z axis for Lemontron

Zest is a Foldable Z-axis (pronounced Zed) modification for Lemontron. It allows for neater and faster setup and storage and should be a near drop-in replacement for Lemontron's Unibody Chassis.

Pint Setting
- Refer to Lemontron's Print Setting, but use slower speed and lower layer height for [Folding Z] for better layer adhesion to ensure its wings won't break from regular use.

Additional parts:
- 2x M2.5x6 Countersunk Screws
- 2x M3x20 Countersunk Screws
- 2x M3 L10 Threaded Inserts
- 1x 172mm Close-loop 2gt Belt

Optional parts for Thumbscrews (as seen in pictures)
- 2x GB806 Through-hole Thumbnut with Throat
- 2x GB807 Through-hole Thumbnut without Throat
- 2x M3x30 Flat Head Screws

Assembly:
- Assemble [Unibody Chassis] as usual with additional 2x M3 L10 threaded inserts on the back
- Using [Folding Z], Assemble the Z-Axis as usual. Replace 160mm 2gt belt with 172mm ones*
- Insert 2x M2.5x6 countersunk screws on [Folding Z]'s wings
- Secure Z Axis assembly with left and right [Folding Z Cap]. Try moving Z axis to see if it is smooth. Sanding may be required to fit the assembly properly, and a bit of breaking in for it so move smoothly.
- Assemble the rest of the Lemontron as usual**

Optional Assembly for Thumbscrews
- Apply Loctite Red 271 on M3x30 and screw in GB807 (without throat)
- Apply Loctite Red 271 on the assembly and screw in GB806 (with throat)
- Wait for Loctite to cure (~24hr)
     (note1: Alternatively, you can also just get M3x20 Thumbscrew, this version has a little more grip and redundant socket for torquing the screw)
     (note2: Loctite is optional, you can use jammed-nut technique instead)

*This allows you to insert the belt into the Z-motor drive pulley while the Z-axis is upright. 
**May need Right Midplate and Topplate modifications for better clearance.
