This is a redrawn-redesigned Vindolins geiger counter enclosure (thing 270764) for SBM-20 tube and geiger counter from eBay http://www.ebay.com/itm/161899914282?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649 . It has openings on the bottom for the SBM-20, as well as on the short side for mode button, on one of the long sides - a little window for the iR receiver and on the other - a cut-out for the power-switch. Print Settings Printer: Mamba3D Rafts: No Supports: No Resolution: 0.295 mm Infill: 15% Notes: This thing already has "mickey ears" for better adhesion so no raft is necessary. Also it should be printed without support (prints better this way). As this thing has long rectangular surfaces, the print speed should be your lowest. It is essential to make your print-bed well aligned as well - all to prevent the possibility of wrapping. I printed in white PLA at 215°C to increase strength of the thin walls and better initial adhesion to the print-bed (cold with buildtak). Post-Printing Actually, no post-printing is required but you can sand the case first with No80 and then with No320 sandpaper. The switch is from mouser.com: http://eu.mouser.com/ProductDetail/E-Switch/R6ABLKREDAF/?qs=sGAEpiMZZMtNT9UGfLL4eD%2ffQBVjEjwGqdlbQiyh%252bKc%3d datasheet of the switch: http://www.mouser.com/ds/2/140/R6-346382.pdf There is a hole for the wire to put into the extended part for the tube. When SBM20 tube is installed it presses against the wire and provides the contact. Another contact can be realized either by soldering or using a 6mm fuse clip.
