Moza SRP-Lite + brake booster upgrade without sim rig

This started as a one off meant for my use case only, but after getting some attention in some forums, I've been asked if I could post STEP files, so here they are.

First off, this is meant to be an upgrade for someone who doesn't want/have space for sim racing rig and wants to use SRP-Lite (and possibly SRP/SRP2) pedals with an office chair.

Second, this is not meant to be a cheap upgrade due to additional cost like 40x40 and 40x20 aluminium extrusions and additional hardware.

Most hardware is assembled with T-nuts with M4 (only to mount Moza base plate to 40x20 extrusions, M4x6mm countersunk bolts) and M5 screws for some adjustability. Exceptions are in 40x20 that sit just under Moza base plate that requires tapped M5 holes and 55mm M5 bolts with hex socket caps and 4x M5 tapped holes on both sides of one of 40x40 extrusions to mount chair castor holders. Additionally, Backs of the pedals have spacers blocks with M5 bolts and M5 nuts (you can use standard nuts, but if you decide to use nylon lock nuts, add additional walls for spacers).
Extrusion lengths will depend on your chair dimensions and your height, but a good starting point is 400mm for 40x20 extrusions and 290mm for 40x40 extrusions.

Couple of explanations:

40x20 extrusions are meant for 2 reasons. To lift the pedal base a bit higher for additional clearance for stronger loop at the front of pedals and to add better stability when pressing brake pedal. The latter one is quite important if you're using brake booster as pedals have a tendency to want to flip over under heavy braking.
40x40 extrusions in my case are bolted through one to another. You can skip this step by either buying or printing corner brackets and connecting them like that.
I highly recommend buying/making 30cm long RJ-45 cable without strain relief and RJ-45 coupler for ease of use and easy disconnect/reconnect action between pedals and wheel base as 40x20 extrusions are going to rob the space for included cable and will make disconnecting post upgrade impossible.
The cable between accelerator pedal and brake pedal needs to be connected before 40x20 extrusion install and needs to be routed through one of stamped sheet metal gaps (yes, there is enough clearance for the cable). Same thing if you're installing clutch pedal.

Material choice is "whatever you have on hand" as I've designed all parts to be a bit overbuilt as long as you don't skimp on additional walls on high stress points. And no supports are needed.

Bonus! I'm including spacers and brake booster base block for 20x10x30mm (ODxIDxL) double spring mounting if you don't like silicone block option. (I've printed them in TPU for AMS for durability, but any material option should be fine)
