I've been wanting to try out the Zwift steerable courses and also upgrade the horrible riser block my IDT came with. I'm probably not on a sufficiently high level yet to do the courses, but I found this SUPER COOL 3D printable design on Thingiverse (similar to this): https://www.thingiverse.com/thing:4239532 I'm curious if anyone else has given this a go (or wants to give it a go)? This is my current print progress (started this morning): I'm using clear PETG filament due to availability ( ), ease of use and low thermal expansion coefficients. I don't have bearings, so I'll have to print those too. PETG is good for moving parts apparently.
