After seeing a battery extender that was just absurdly large (100 MB with over two million faces -- enough to crash slicers and Blender on my iBuyPower gaming rig) and providing constructive advice to improve the design in the comments, I took it upon myself to just fix the problems but wait on posting them in case the designer was willing to fix the problems. Instead, he opted to wait a month, respond to not my comment from 1 month prior, but a completely different comment from 14 months prior (which I found to be quite rude), and has posted four designs since my comment (even more rude).

So I fixed it myself because that's what Thingiverse is all about. Having waited a full year, I think it's fair to say the original design will never be fixed, and I also have sufficient field data to say that my adaptation works quite well. And rather than over 2,100,000 faces and 100 MB mine weighs in at 164 faces and a mere 8 KB -- Kilobytes, as in 8,284 bytes total, using the larger V3 design which uses additional geometry for notches for non-permanent installs.

V1 does not include these notches and as a result it requires adhesive (in my case superglue) to hold it together. Works quite well for PLA, but the notches are there in case of battery jams -- which I have often -- to allow easy disassembly to free batteries and prevent having to shake the entire unit like I do now. You can still glue it should you so choose -- just download V1 (no notches). If you don't want to glue, download V3 (with notches). Changelog below has details on design changes.

Outstanding issues

• I never liked how the notches allowed the design to come apart too easily. A thought is to also adapt the main base to include heatserts where the notches would cover, and have countersunk socket cap M3 bolts inside the notches to secure the parts together. With sufficient clearance, this would allow a removable point of attachment should a jam occur and/or should height need to be adjusted while also allowing it to operate as one single unit.

Changelog

2018-12 - V1

• Initial Design
• Requires superglue for assembly
• This version is tested and working

2018-12 - V2

• Deprecated, faulty design, not shared as a result
• Added notches to the inside for a flush outside finish
• Inside notches impede battery operation so this was scrapped before testing

2018-12 - V3

• Migrated notches to the outside, allowing for a gravity-fit
• UNTESTED

2019-12-17

• Initial upload of V1 and V3
