In other words make the trial rack and case very short.  Test the fit with the battery or batteries in the rack.  If the fit is bad, adjust the case either through OpenSCAD or your slicer. \u003c\/p\u003e\u003c\/blockquote\u003e\u003cp\u003e\u003cstrong\u003eOther recommandations : \u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eit makes sense to print the sheath with transparent filament (see some of the photos on the original model)\u003c\/li\u003e\n\u003cli\u003eif you print “rack” and “sheath\" on the same plate, it's probably adviced to print with as sequence “per objects” and not “per layers”.

But, of course, your mileage may vary (depending on your settings, filaments, …), hence the need to do a small test with a “1x3” model. \u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eHistory : \u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eNew in v2, per the author of that version : \u003ci\u003eI added an optional bump near the back of the sheath so that the rack gets pinched and therefore does not slide out if tipped.  The bump size is adjustable via the OpenSCAD source.
