sinc-case's Introduction

Sinc Keyboard Case

Here are the case design files for the Sinc. The .ai files have multiple layers to toggle on/off to generate the correct set of plates/mid-layers/etc.

It's suggested to use the enclosed design.

Plate Files

In the plates folder, there are DXF files of the switch plates and bottom plates. These are the same design as the FR4 plates that are sold. The switch plates are designed for 1.5-1.6mm thickness.

In the enclosed-case folder, there are STL files for a design where the FR4 switch and bottom plates are used but have their sides covered. The top shell has been designed to be threaded into directly from underneath using long M2 screws.

For the Rev. 2-4, you will need M2 screws that are 16mm in length. For Rev. 1, due to the thicker mid layer, you will need 20mm screws.

SKUF Alignment Guide/Tool

For aligning the SKUF feet so that they are straight, you can print off this tool to help you apply the SKUF feet better: SKUF Alignment Guide

Older Design

The original case design can be found in the older-design folder. The design there can be used to make a stacked acrylic case

sinc-case's Issues

Weird fitting with rev 1

Hi! I think I have the same "problem" as #2. The PCB and a bit of the trrs plug seem to be pushing the case out.

Some pictures:

I didn't understand the resolution to #2? Is it supposed to be like that? Do I need to desolder my pcb to use this case? Is it just a bad print?

will there be have the rev.3 enclosed case file released here?

New enclosure rev 1 design problem.

The rev1 pcb connectors do not fit the current enclosure design.

Expected Behavior

The pcb should just pop in. The tssr connector is too big for current hole. The USB-C might be problematic too.

Current Behavior

Pcb does not go in fully when assembling. Tried to install normally but I could not get it to fix.

Possible Solution

Enlarge the connector holes. I fixed this in a minute by plunging a soldering iron throw the holes in order to enlarge them. Would not recommend.

Context

Was not ideal for my build. Altough I wish I did not have to enlarge the holes with an soldering iron.

Difference between the right and right full case?

From here https://keeb.io/collections/split-keyboard-parts/products/sinc-split-staggered-75-keyboard?variant=32113454383198 I understand there's a left side with no macro and left w/ macro version, but what's the variation on the right side?

Clarify requirements for enclosed case.

Hi,

I have recently purchased sinc prebuilt from keeb.io which comes with the FR4 plates and have a couple queries

What are all the items i need if want to print the enclosed case? I think:

Top Shell - Left Macro with Encodes
Top Shell - Right with Encoder
Mid Layer - Rev 2 Left Macro
Mid Layer - Rev 2 Right

Questions:

Do i also need 'switch-plate' and 'Bottom-plate' (or are these part of the pre-built)?
What is the 5mm plate used for?
Also, is it possible to get the enclosed case files in STEP format? The place where i am sending the print requires STEP.

Many thanks!
