Simagic Alpha Mini Wheelbase mount. May work for other Simagic Alpha wheelbases but I only tested this on a mini.

2 Positions - One is flat and the other is set at a slight angle.

Uses M6 x 12-15mm flange head bolts. If you can get flange head hex with washers should work but might not clear the opening.

Printed with PETG at 70% infill and it's held up for 10+hrs of use. No supports.

2 files: 1 with a single bracket and then you just need to mirror the 2nd. The other file has both brackets.
