Back-plate for a 2007 Ibanez RG1570 Prestige. Might work on other RGs and/or other years. Not sure. Designed at 138.85mm x 85.7mm dimensions.

Also included is a modification that would be useful if you installed a Tremol-No locking bridge (which you should). It opens up access to be able to engage and disengage it without having the plate off.

Print instructions

Print flat obviously and with the outside facing down for the best finish . Was my first ever design in Fusion 360, I started on the wrong origin, and never "fixed" it.

Beveled edge and screw whole print best at .1 and needs no finishing, but .15 is ok. Variable layer height would be good here.
