ISO: Woodstock battery pack - jupiters_spot - 09-12-2016 11:19 PM I'm trying to equip my collection of HP-21, 25, and 27 calculators with working batteries, but I'm short two of the plastic battery packs. I'm looking for part number 82019-B, which is the beige-colored battery pack holding two AA-cell NiCad batteries. I can replace old batteries, but it's hard to fabricate a replacement plastic part that matches. If you know where I can find one or two of these, please PM me. Referring to a link on the museum site, this is what I'm looking for (with our without batteries -- I just want the plastic holder): Thanks! RE: ISO: Woodstock battery pack - Nate Martin - 09-13-2016 04:13 AM You might want to check this thread in the general forum: http://www.hpmuseum.org/forum/thread-6818.html I will probably have some models available on shapeways by the end of the month, not quite the same finish and color but workable at a cost of ~$17 (a little over $12 for the top and bottom of the case and about ~4.50 shipping based on what I ordered today) for the case alone without springs or batteries. RE: ISO: Woodstock battery pack - Dave Frederickson - 09-13-2016 04:56 AM Check out some of Nate's other work here: shapeways.com/shops/hpparts RE: ISO: Woodstock battery pack - jupiters_spot - 09-13-2016 02:31 PM Printed parts - sounds yummy! I'd love to see a photo of a final product, as opposed to the CAD rendering. Are you printing in PVA? I also wonder whether folks know of a reasonable place to buy springs? Clearly won't be printing those, but having a spring will be a nice element. Great work, Nate! RE: ISO: Woodstock battery pack - Nate Martin - 09-17-2016 03:12 AM I expect the 2nd rev cases sometime next week. Once I have in hand I will try to upload pics. as for springs, there is a source on ebay that people were using for the 41C battery cases (although I thought they were a little big) that seem to fit well. search for "Dual Copper Spring Coil For Dual 18650" frequently used with vaporizers. RE: ISO: Woodstock battery pack - Dave Frederickson - 09-17-2016 06:42 PM Nate, Would you be interested it taking over your models from the hpparts shop? To date, folks have bought $760 worth of your model parts. I think you deserve to be rewarded for your contribution with some profit.
