DimSim R1 Button plate

thingiverse

FYI I'm working on a new design with an integrated vocore screen, more 12-way switches, a more "ergonomic" rear and integrated shifters. It'll probably be 2 months before I finish it as I'm now building a Voron V0.1 which is my focus for the time being. ------------- Updates: ButtonCapV2-Aux.stl This cap works for the bottom 3 buttons ButtonCapV2.stl This cap works for the top 6 buttons MutiPosCapV2.stl & MultiPosSwitchV2.stl Redesigned multi-position switch R1_wheel v57.step I've now included the Step file so you can import & adjust. I removed the DimSim supplied DXF from the design as it's not mine to distribute - if you require this I'd suggest contacting DimSim (they were very keen to help when I reached out). Original Posting: Designed for use with SimuCube SQR but likely compatible with other 70mm mounts. I've seen a couple of button plates for the DimSim R1 (https://www.ebay.co.uk/itm/DimSim-Steering-Wheel-R1-SIMRACING-/183784911114) but fancied doing my own. The main difference here is the multi-position switch in the centre which I use to control the functionality of the bottom 2 encoders - this is possible thanks to FreeJoy (https://github.com/FreeJoy-Team/FreeJoy) I also didn't want a wheel that was too busy - I mainly play Assetto Corsa Competizone, so don't need too many buttons - particularly with the multi-function switch functionality. Shifters: I've modified these ones https://www.thingiverse.com/thing:3468245 to provide a physical endstop, utilise 10x10mm magnets & provide a different shift paddle - https://www.thingiverse.com/thing:4590694 BOM: 2x 2.5mmx12mm (for multi-switch assembly) 6x m4 10-15mm (dimsim r1 to backplate) 8x m4 6-12mm for rear-plate 1x gx16 connector (4-pin) 2x leobodnar cts 288 short shaft http://www.leobodnar.com/shop/index.php?main_page=product_info&cPath=98_75&products_id=243 (optionally cts 288v short shaft if you want additional push button) 9x push button https://www.aliexpress.com/item/32958866526.html?spm=a2g0s.9042311.0.0.515a4c4dNCFhEO 2x microswitch for shifters https://www.aliexpress.com/item/32850956248.html?spm=a2g0s.9042311.0.0.27424c4d6E0p39 3x m5 30mm-40mm (to mount SimuCube 2 QR) 3x m5 nylock nut 6x m5 washers 3x m5 x 10mm Alu washer https://www.aliexpress.com/item/33052017430.html?spm=a2g0s.9042311.0.0.27424c4duaeOPx 1x STM32F103C8T6 "bluepill" - (make sure to buy STLink v2 mini as well for programming with FreeJoy - I tried to do it with an arduino but had no luck) https://github.com/FreeJoy-Team/FreeJoy 30awg wire has been sufficient for this project, however I did use awg 28 for the USB -> GX16 pin. Note that USB can be taken from A11 and A12 from the bluepill board (see the FreeJoy configurator for layout). The top 6 push buttons mount to the button plate, The lower 3 mount directly to the DimSim R1 The 2x encoders mount directly to the DimSim R1 using the "Encoder-mount" - you may need to use locktight or superglue to secure these (so far mine have been fine on friction)
